Curious what engine oil y'all are using or planning to use? I'm getting ready to do the first oil change @ 500 miles. Not sure where to get a fully synthetic oil with the recommended viscosity? Dealer?

I have not received my Shelby yet but in preparation I just purchased Castrol. I had a hard time finding 5/50 but Auto Barn was the only store in town that stocked that product in my area. The oil filter is the same as the filter for any ford 5.4.

For what it is worth,at this time the only oil that is certified for the Shelby GT500 is Motorcraft full synthetic 5W50.Next year Syntec (Castrol) and Mobil 1 full synthetic will PROBABLY be certified but if you have engine problems and you have to prove what motor oil you used you will not be covered under warranty.Saying that a new Shelby motor runs $18,000.

Wow! That's pretty harsh. I mean, really, how different are motor oils these days, particularly the top tier ones, when it comes to engine protection? I would think, as long as you're not using some off-brand, recycled sludge, the warrant wouldn't be an issue. Just shows you how much I know.

I did a lot of research on this subject for my own personal reasons.I forget off hand what the spec. numbers and letters are xxxxxxxxxx-A are Castrol and Mobil 1.For the Shelby it has to bexxxxxxxxxx-B,and the only one that meets the spec at this time is Motorcraft 5W 50 full synthetic.I checked with Castrol and Mobil and Ford and this I know for sure.I bought Castrol and took it back, the Ford dealer said they would change it for $65.00 + tax.I did get another quote from another dealership for $130.00.Check around........................07.................. ............

$130.00??? That's insane.

In case you wanted to know, the actual specs numbers are:
WSS-M2C931-A - API SL, SAE 5W-50, FULL SYNTHETIC
WSS-M2C931-B : API SM, SAE 5W-50, FULL SYNTHETIC

I read on another board that the early owner's manuals referenced version A, but later ones seem to be referencing version B.

Edit: You are absolutely correct. Castrol is rated to version A (SL not SM)

I just read the PDS for Castrol Syntec 5W-50, and it states, "Exceeds all car and light truck manufacturer's warranty requirements for the protection of gasoline, diesel and turbocharged engines where API SM, SL, SJ, SH, CF or CD is recommended" even though the oil is certified to the WSS-M2C931-A specification and not the WSS-M2C931-B specification.

I'm not sure what to think now. :confused:

I talked to Castrol (they have a lot of ties with Ford) and they specifically told me and so did Ford that it is not approved by Ford at this time.Castrol expects to be approved by the middle of ............07............Some will think I am splitting hairs here but the reality of it is, if for any reason you have engine problems and did not meet there requirements for any reason(and they will ask for receipts)you void their warranty.I have gone over this subject extensively with the Factory rep(Ralph Arning),Castrol,Mobil 1 and the dealership.Take it for what it is worth,$18,000.............07............

I believe every word of it, 07. I just think Ford is being entirely too anal about this.

Because I didn't feel like working very hard today, I decided to read the Ford specs and the related ASTM and API specs. From what I could tell, the difference in performance requirements between SM and SL ratings is negligible.

Anyway, I'm going to skip out of work and have a couple of beers.

Bravo,go have a cold 1,2,3,4,5 or 6.By the way I am with you but I want to tell the facts.

Ok, here is some more info to further "muddy" the waters...

1. I have not found an "SM" rated Motorcraft 5w-50 full synthetic oil listed or sold at any Ford dealer.

2. I checked "API's" website and now I know why. There is none yet available according to the following information...

http://eolcs.api.org/DisplayLicenseInfo.asp?LicenseNo=0110

Here is the link to the API listed 5w-50 oils...

http://eolcs.api.org/FindBrandByViscosity.asp?Viscosity=5W-50

:confused:

There was a post in another thread(I don't know where)that their mechanic said there is an additive in the oil from the factory for break in on the engine.I have never heard such a thing so I talked to the rep from Romeo Engine Plant and he said it is not true.He said just drive that car.

Thanks, 07. I was wondering about that myself. I thought "break-in oil" went out a long time ago, but that other post made me wonder.

I believe the break in oil is by Jack Daniels.
It is used after (No Prez.not during)the first ride.

I just changed my oil for the first time. Used TropArtic 5W50 Synthetic. WSS-M2C931-B certified. Got a case for $59.95. Got oil filter at Walmart for less than $4.00( motorcraft recommended filter per manual). Lot easier to change the oil than I thought. The oil I removed appeared to be pretty dirty. I have 1990 miles on it.

What we need to find out is who makes the oil for Ford, which I am guessing it is one of the big 3 companies. Lets face it Ford does not have a oil Refinery. Same with their oil filters, I use to work at a car part store back in the day and a motorcraft oil filter for my 302 mustang was made by fram but the motorcraft cost more go figure. I have already changed my oil and when I went to the Ford Dealer it was something like $ 13.00 a quart...Don't tell anyone but I put in Castrol Full Syn. I did buy a motorcraft oil filter... .because I could not find a purolator filter at the local Auto zone :(

I understand why compaines do this.. and not just Ford but all car compaines and motorcycle compaines as well, my busa calls for Suzuki lube which the dealer will gladly sell to me for twice what I can by Mobil Syn motorcycle oil for and running at 11,000 to 12,000 rpms never has any of my bikes had a problem so I won't be changeing to Suzuki lube :)

Not sure about oil filter spec's but 2 years ago one of my car magazine did a review of filters, cut them in half...did all the things to a filter we would never do and at the time the purolator was #1 and also was mentioned they did not use paper in their filter which they proved the paper element after some time did not filter as good as it did when new.

I will take my chances using Castro unless someone finds a good internet site that sells the motorcraft at a fair price. However very good information 07 and it is appreciated for the heads up.

Ditto busababy. I have been using Fram filters for years and have never had a problem. Unfortunately Fram, as far as I know, does not make a racing version for the 5.4, so I have been using the standard version, which if my memory is correct is PH2. I also have been using Castrol Syntec for the Shelby and will take my chances. Just my opinion.

I guess I don't understand the issue with not using the Ford approved Motorcraft 5W50 synthetic oil. Is everyone really trying to save $3/qt in a car that costs north of $45K? Penny wise and pound foolish if you ask me, but to each his own.

I got my oil(7 qts.) changed at the dealership for $63.00 with filter and labor.Plus I went to watch him change the oil and check it for shavings.

For me the money is the least of the worries, I want the best oil out there and not sure it is Ford. Ford does not make oil still trying to find out who does make the oil for ford. Whoever does just puts it in a motorcraft bottle and sends to Ford, I have worked in manufuturing for the past 23 years and see it all the time. I worked for VDO for 15 years we made gauges for all Germany cars, than we started to make guages for John Deere, GM, not sure we ever made anything for ford, but no matter who we would make the guage for we would silk screen there logo on it. We weren't the best gauge out there but we would bid lower to a company like GM so we would get that job. I don't want to use oil that Ford has choosen just because they bid the lowest to produce the oil for them. Me personally I do not like quaker state and if quaker state came in at the lowest quote than they got the job and we are using that oil. (Like I said above I don't know who makes Fords Oil quaker state is just an example) I am sure the Ford oil is good but since I don't know about it I feel better with the brand I do know.

Boys

I believe (and have evidence to show that) the oil sold by Ford is made by Castrol. Have you noticed the "Ford recommends BP" on your gas cap? Well, have you noticed the BP symbol on the Castrol box? The Castrol 5w-50 meets the specs spelled out in the manual.

That's what I've been using and feel very confident that it will meet factory specs, etc. My local dealer said he had no listing of 5w50 MotorCraft oil and wasn't sure he could get any so I HAD to go elsewhere and that's what I've come up with. Hope that helps.

Blue Oval thanks for the information. Very interesting study and I will rethink my next filter purchase. Correction, just ordered a case of Baldwin's and at $5 a piece sounds like a good Christmas gift for my Fords.;) Think as soon as they arrive I will do an oil change and get that Fram Extra Guard off ASAP.

No problem. Merry Christmas.

Talked to the parts guy at Ford over the weekend and he told me that Conoco was the source for the oil. I never have heard of them so did some research:

ConocoPhillips is a huge integrated oil company in the same league as
ExxonMobil, ChevronTexaco and Royal Dutch Shell. They make their own base oils and blend and market brands like Phillips66, Conoco, Union76, Kendall, and yes, Motorcraft

Found this on the web:

Received this directly from Conoco Phillips.

Yes, we manufacture Motorcraft lubricants for Ford Motor Company to their published specifications.

Still not 100% sure just what I have read in case anyone cares.

I too went this wekend to the dealer where I purchased my car to see about oil and no luck. The manager said he was going to look into it. I asked the question how were they going to change my oil when they did not have the correct oil. They said that they would not have done the oil change and I said well they wouldn't have known the difference. The parts manager never heard of the oil. What a waste of my time that would have been. Not that I was going to have them do it anyways.

Manager just called and said he has a case of oil on its way.:)

I put it in a thread a few weeks back that I researched and used TropArctic 5W50 synthetic. It is the only oil that specs out the correct Ford oil for the GT500. I got it for $5.00 a quart. I also know it is the oil used by Ford. For some reason everyone on this forum chose to ignore my info. Troparctic is made by Conoco/Pillips, a very large oil co. This is the last time I give out any info on this forum so you can take it for what its worth! I don't like being ignored, especially when I have the correct info, but because I am not a member who has a lot of posts they seem to be ignored.

I hate to see that you feel ignored. I really think you are taking it too personally, though. I remember seeing your post. I have been looking for that oil since then, and have not been able to find it. Where did you get it? Thanks for the info.

Are you sure this isn't the thread you posted in?

Where are you getting your oil? Is it only at Phillip66 gas stations? I have only been able to find Castrol at all the auto part stores. I have run into the exact same problems with ALL Ford dealers including the one I bought the car from! They all question " are you sure you mean 5W50?" Defintely would not let anyone change the oil for me.

Thanks

That's not true.
Sorry you feel bad.Mine is in semi-storage and doesn't need to be changed.We all appreciate the facts but if you are waiting on a lot of thanks from people it just doesn't always happen.People love the facts but are slow sometimes to show appreciation.I think I give out as much as anybody but I do it because I want to.They only appreciate it when they need it.Thats how humans are.Don't be offended.........................07............... ...........

I couldn't have said it better 07, vote you President.

Why can't we all just get along?




All the info given here has value.

The case of 5W 50 Motorcraft oil just showed up and the dealer said that would be $105.00. Of course I said @#$% so they only charged me $95.00, oh what a relief. Since the sarcasm.

Well said '07.

Where the heck do you get the TropArctic?!?

I emailed them today asking where to purchase this oil, since it looks like this is motorcraft oil. If someone has a bottle of the motorcraft at home look on the bottle for a part number and do a search with google it should show someone that sells it.

I changed the oil today for the first time and saw something I have never seen in my many years of car maintenance...When I removed the oil filter I noticed "rust" all around the sole plate at the base of the oil filter. The filter was dry and I NEVER drive when conditions are wet. I might also add I was less than impressed with the quality of the stock filter.

I filled with Motorcraft 5w-50 full synthetic and a genuine Ford Racing filter of much better quality.

Got this back this morning from the makers of Motorcraft Oil:

Well my first oil change was 15 bucks, an attempt to get me to pay the 89 they said was the non coupn charge...The dealer didn't give you the first change freebe??

I havnt let anyone work on any car ive ever owned...not even to change wait especially not to change oil, its either wrong oil used, over or under tightened filters, spilled and overfilled oil, you name it!! And dealershipe are the worst...BEWARE learn to work on your own vehicles.

TRIPPLE DITTO - # of posts means nothing. Quality of posts do. Especially when you're sharing good intel..............

Stick with it dsabldvt.........

I gave this thread a bump up because being a new owner of a GT500 I found it useful and had done a lot of searching on the web before eventually finding it.

I am a huge Mobil 1 fan, but I think I will go the Motorcraft route with my first oil change. But some of the posts about the oil filter scare the crap out of me, but perhaps a ford racing filter.

Next time I will have time to track down some Mobil 1, but anyways, good info for new GT500 owners.

if you stick with what came in our cars then all you're questions will be answard

Castrol 5w50 meets the SF/CM spec required by Ford as does Mobil 1 5w50. The Mobil 1 5w50 has a limited distribution but you should be able to find it at Porsche and M-B dealers. TropArtic and Ford are not your only 5w50 options that meet spec. You should send in an oil sample to see how long you can go in between oil changes based on your location, driving habits, and performance modifications. Most oils contain a disclaimer that the extended oil change intervals are void once modifications are introduced. The sample removes any personal bias such as 'I've always used X oil and it's great" or "I hate X oil because....".

The Castrol oil does not meet the B spec that Ford specifically calls out, which is why everyone is questioning it. I have done a lot of reading on this lately, and it was mentioned in early 2007 that Castrol told a member of one of the forums they would meet the B spec by the end of the year. Well, they still haven't met it, does anyone know why? Did they test and fail, or just not test it? More importantly, I really want to run the Mobil 1 15W-50, but am not willing to run out of spec. So I'm torn between the Castrol and Motorcraft. I guess the big question is, has anyone sent their Castrol in to Blackstone or one of the other oil labs to see how it wears? If so, how many miles did you run it, how hard do you drive, and do you have any mods?

I have 19K miles on my car now, 12K of that with the KB on it, and I've been using Mobile 1 15W50 full synthetic at each oil change with no problems at all.

I think you guys are being a little to anal about this stuff. I agree with the other poster who indicated that as long as you are using a quality oil/filter on the car, you are not going to have any problems. of course, I live in a warmer climate than some, so using a 15W50 versus a 5W50 is not a big deal. Either has the same viscosity at operating temperature.

If so, how many miles did you run it, how hard do you drive, and do you have any mods?


The newer API SM spec superceeded the lower zinc specified in the Ford "B" revision. It also provides for better wear properties.

In effect, the Castrol did meet the spec, they tested and labeled to the industry standard spec.

Exactly. The API spec on the Ford 5w50 is SM/CF. Castrol meets spec. But, as you said, I'd like to see an oil analysis as everything else doesn't really matter.

I just bought my Shelby, and the dealership gave me two yrs of free oil changes. I thought that was an SVT thing or something, but apparently not? They also told me that the first four tires I wear out are replaced for free...regardless of reason. Again, I thought it was an SVT thing, but apparently this is a dealership thing.

It's definetely a dealer thing, many members paid a generoius ADM and didn't even get a free dinner before getting kissed good by.

My service writer said it's OK to use Mobil 1 15-30

I think I am going to stick with the Mobil 1 15W-50. Being in Florida, I don't have to worry about the freezing temps, and in theory a 15W oil will protect better than a 5. Good to know you got a nod from the service department. I've always had good luck with Mobil oils, so why change. Besides, it's readily available where I am at, so that helps a little too.

Garagelogic, did you notice a difference when you switched to Mobil 1? I know it's been a while for you, but it almost seems like the motor is freer revving with it. Thought it was interesting, wondering if anyone else noticed?

Just a heads up on a great sale price...

Autozone has the Castrol Syntec 5W50 on sale this week. 5 qts and a K&N oil filter for $29.99

I prefer the PureONE or M1 filters but its still a good deal.

As long as the sheering qualities of the Mobil 1 can handle the GT500 motor/supercharger....

Great find. I went up and bought this deal because I remember paying closer to $6 a quart for my Castrol Syntec 5W50 the last time. This oil meets all the required specs and I have never had any problems with using this oil in my Shelby and am confident in using it. I do spend the extra $2 for the Motorcraft oil filter, but that's just my preference. Research shows it's a good filter - plus I like the Motorcraft name on the side of it.

I just found this on the web and thought that I would add to the oil quagmire. Roush via Valvoline now offers synthetic oil that meets all of Ford’s spec requirements. See the link for details.

I know when my dad had his lightning we used royal purple in it.we use it in all of our vechiles now.i was wondering i dont know enough about oil but they have a oil they call xpr by royal purple good for supercharged and turboed applications i heard and some other oil 5w30 or something.just thought i would mention it.

Good luck finding that Roush oil. If you do let us know where you can buy it and cost.

I just did my first oil change with Mobil 1 15w-50, and noticed it was a little dirtier than the Motorcraft came out. Not sure if it is because it is cleaning better or breaking down faster.

Ok ,,,oil For The Beast That Meets The B Spec. Go To Kmansparts.com. They Have The Motorcraft 5w 50 Full Synthetic Oil For 7.99 A Qt,,,the Fl820s Oil Filter For Under 4.00 And The Fa1807 Air Filter For Under 26.00. The Ford House In Greenville Texas Did Not Know About The Oil Or The B Spec. Said They Would Have To Look Around For It. Not Too Good For A Ford Dealership. But These Folks At Kmansparts Are Quick On The Orders. I Ordered Enough For 3 Changes And It Shipped Th Same Day

+1 for the royal purple

Castrol 5-50 syntec. Been using it since first oil change. It's less expensive and more available than Motorcraft. They are both fine synthetics, not enough of a difference in either to pay the dealer's blackmail prices for Motorcraft.

GO TO WWW.ROUSHPERFORMANCE.COM AND CLICK ON PARTS. YOU CAN BUY THE ROUSH 5W 50 FULL SYNTHETIC FOR 99 DOLLARS AND CHANGE FOR A CASE OF 12. ONLY THING IS IT TAKES SIX AND ONE HALF QTS FOR AN OIL CHANGE. REALLY NEED A BAKER'S DOZEN

For what it is worth,at this time the only oil that is certified for the Shelby GT500 is Motorcraft full synthetic 5W50.Next year Syntec (Castrol) and Mobil 1 full synthetic will PROBABLY be certified but if you have engine problems and you have to prove what motor oil you used you will not be covered under warranty.Saying that a new Shelby motor runs $18,000.

Legally this cannot be done; if a vendor publishes that the only lubricant to meet warranty obligations is their own they have to provide it for free to the consumer. What they can do is say that the oil used must meet specifications of "x". Mobil 1 is what my SVT dealer uses and a little birdie told me it is also what is in the Motorcraft bottle.

Someone made a comment about using any 5.4 oil filter; this is an area where it does make sense to buy the branded one, Ford Racing # M-6731-FL820. You may spend a couple of dollars more to get it than a *cough* Fram but this is not a cheap oil change to begin with so why scrimp on filtration?

One other recommendation; go to your local Caterpillar dealer and pick up some SOS (Scheduled Oil Sample) kits; these range from about $15-20 depending on the dealer but they include the shipping to the lab and the analysis. You will appreciate having this history if you ever get into a problem with warranty coverage and if you are not comfortable interpreting the results drop me a line. You can use these for any fluid; I sample all my oils at every service interval.

I have 19K miles on my car now, 12K of that with the KB on it, and I've been using Mobile 1 15W50 full synthetic at each oil change with no problems at all.

I think you guys are being a little to anal about this stuff. I agree with the other poster who indicated that as long as you are using a quality oil/filter on the car, you are not going to have any problems. of course, I live in a warmer climate than some, so using a 15W50 versus a 5W50 is not a big deal. Either has the same viscosity at operating temperature.

So I thought I would share some info as a lot of people do not understand oil standards; generally you should run as low a bottom # as you can find (and afford maybe). When you plot out the properties of oil on a chart a 5W50 will provide more protection at both the lower and higher ends of the spectrum than a 15W50. I was going to put a chart on here but apparently I am unable to do it yet or something....here is the link http://www.imperialoil.com/Canada-English/Files/Products_Lubes/Visc_Temp_Chart.pdf All you have to do is plot out your oil on this chart; the data sheet will give you the temps to use, both temperature points are SAE standards. When you plot it out you will see that a lower number provides significantly more protection than a higher rated one.

The biggest concerns for any lubricant are what it does under extreme heat and what it does under low heat at start up. In an overhead cam engine it takes a lot longer to get oil to the valve train than in a pushrod engine.

Both oils use the same basestock to get the 50 rating; modifiers are added to lower the viscosity at the bottom end and not the other way around. So long story short, why do you want to hurt your engine by using a 15W50 instead of a 5W50? A lot of people seem to think that the lower number should match the ambient temperature of where you live....not true; it is a viscosity rating not a temperature rating. If I could find a 0W50 I would run it as the band of coverage would be exponentially larger.

EDIT: here is another chart worth reviewing.....http://www.imperialoil.com/Canada-English/Files/Products_Lubes/Visc_equiv_eng.pdf

While your point is well taken, a few of your facts need to be corrected. First, with regard to the OEM oil, if Ford REQUIRED you to use FORD oil AND NO OTHER they would fall under the clause where they would have to provide the oil. They publish a spec, how many vendors choose to offer a product that meets the spec is market determined. Ford offers one. Which is currently manufactured by Phillips under contract and labeled as Motorcraft Full Synthetic 5W50.

BP (Castrol brand) also has a product in its Syntec line that meets specs and has been recommended specificly by SVT as meeting warranty requirements. Its used by many dealers where motorcraft is not as easy to get.

Lastly, the filter required for the GT-500 is the Motorcraft FL-820S, not the low restriction version from Ford Racing. The FR version does have a thicker can and some other improvements but the filtering efficiency is actually lower to provide less restriction and improved flow for racing applications. Use the $4 FL-820s and do your car and your pocketbook a favor.

Currently ExxonMobil does not have a product in the US that meets the 5W50 API SM spec requirement.

Not so sure on the comment on the filter, Ford recommends it and it provides more filtering efficiency; restriction and efficiency are only relevant comparisons if you are talking about the same media and pleat count per inch (in other words if you make the micron rating in the media higher and maintain the pleats per inch yes restriction and flow efficiency change inversely proprotionately)...cut one of each open and you will see the difference. You can have less restriction and increased efficiency with a higher pleat count using the same micron rating as you have more holes of the same size per square in of media. Like I said, cut them open and if you still disagree come tell me.

Hmmm....Mobil have the certification in Canada, wonder why not down there....http://www.esso.ca/Canada-English/Files/Products_Lubes/IOCAENPVLMOMobil_1_5W-50.pdf

Motorcraft FL-820s vs Ford Racing CM-6731-FL820 Oil Filters

--------------------------------------------------------------------------------

I thought you guys would be interested in reading this comparison study because so many people are under the impression that both of these filters are exactly the same just different labels. Look at the difference in total square inches of filtering media surface, Ford Racing is 250 square inches compared to 156 square inches for the Motorcraft, that's 94 square inches less! A larger filtering surface means more oil flow and greater filtering capacity. I get my Ford Racing filters from LateModel Restoration Supply OIL FILTER, FL820 - HIGH PERFORMANCE MISCFORD for $12.99. The Ford Racing filter is built using thicker metal (noticeably heavier) for the can material and the threaded base plate is real beefy with deep high quality machined threads. I was using the K&N HP-2010 until I read this article. The Motorcraft and Ford Racing Filters both utilize a base end mounted bypass valve instead of a top dome mounted bypass valve like the K&N and Purolator models. You can read about the importance of the bypass valve location in the oil filter comparison link I have attached for you below.

Sorry to bring this thread back...this was one of the search results for oil changing...so I CAN use Castrol Syntec 5w-50 in my car and still ok w/ Ford or no?

Then again it may be a moot point because I plan on going with an EVO stage 4 in a couple years too, so there's that.

to keep things simple most here will say use what ford says to use, one that has the spec B.

I believe the only ones are still the motorcraft and roush

If you are out of the warranty period then use what you want. Considering mine is a daily driver and I put about 3K a month I went with the roush and follow the service manual change interval.

You have to order the Roush but the price differnce is only a couple $ a quart. The Castrol is around $6 right?

A case of roush shipped came up to 110.10, yesterday when I ordered.

I looked on the roush website aleady and searched "motor oil" and it brought up a bunch of oil but none were the 5w-50 spec. Then I tried it from another link that talked about the oil and it said the product isn't available.

Found Kmans parts for the motorcraft stuff...with shipping it ended up being about $8.xx per quart when I purchased 13 quarts. Not too bad...though I'm partial to Syntec.

edit:

After doing more product research, here is what is in writing for Castrols SYNTEC


SAE 5W-50: provides the widest range of protection available. SAE 5W-50 delivers exceptional cold temperature
pumpability for rapid oil circulation at start-up and provides a thick oil film for ultimate wear protection. Exceeds
all car and light truck manufacturer’s warranty requirements for the protection of gasoline, diesel and
turbocharged engines where API SM, SL, SJ, SH, CF or CD is recommended. Exceeds European ACEA: A3, B3;
Ford WSS-M2C931-B and the engine protection requirements of ILSAC GF-4 for API Certified Gasoline EngineOils.

So it would seem it IS an option even during the drivetrain warranty.

Convert, thanks for that look-up, as I am also partial to Castrol, I will go that direction!

That's what this site is for. To help fellow owners out.

The best part about it is that it's $6.99 / qt at Autozone and normally stocked.

I ordered mine from Rouch no problem...right about a hundred bucks a case with shipping. I'm only about 40 minutes from them however and plan on taking a ride over there to pick up a few cases for the future when I get a chance to put the top down on a nice day to save the shipping costs. Its not like its gonna go bad on my shelf in the next two years. Its a great excuse to go for a ride anyhow....

thanks for these information

There are three that meet the ford B spec. Ford motorcraft, Valvoline and Castrol. I have found this in the manufacturers printed brochures on line.:)

not trying to argue, but this is what I found.

This is from Castrol USA

SAE 5W–50:
provides the widest range of protection available. SAE 5W–50 delivers exceptional cold temperature pumpability for rapid oil circulation at start–up and provides a thick oil film for ultimate wear protection. Exceeds all car and light truck manufacturer's warranty requirements for the protection of gasoline, diesel and turbocharged engines where API SM, SL, SJ, SH, CF or CD is recommended. Exceeds European ACEA: A3, B3; Ford WSS–M2C931–A and the engine protection requirements of ILSAC GF–4 for API Certified Gasoline Engine Oils.

http://www.castrol.com/castrol/genericarticle.do?categoryId=82915470&contentId=6006933

But I also found the page that you must have read. Which is it? Guess someone will have to read the bottle.

http://www.castrol.com/liveassets/bp_internet/castrol/castrol_usa/STAGING/local_assets/downloads/p,q/pds_syntec_usa.pdf

As long as I've got the boldened text that I quoted earlier in a Castrol document that I can show to Ford...that's all that matters to me! lol

However, for the sake of clarity--what are the dates for the documentation that differs from what I found? Perhaps one is newer than the other?

That conflicts with their PDS which claims WSS-M2C931-B.

For what its worth, my Ford Dealer just did an oil/filter change for me and they used the Castrol Syntec 5w-50. They said it was the one the Ford parts dept computer was saying to use. I have no problem with that and the car is running just fine...
Even stranger though... the computer specs for them to have 8 quarts on hand to do the service. It took exactly 6.5 quarts to hit just above the middle of the dipstick mark, so they gave me the extra 1.5 quarts to keep at home.

ok folks ,,,put the WSS number in your search engine and go down and find the PDF entry for castrol,,,,it is dated april 2008,,, and see on the 5w 50 entry that the castrol meets the B spec. It meets the A spec also. :)

I am sitting here with the bottle in hand, the bottle states Meets Ford WSS M2C931-A. The PDF sheet for MSDS on Castrol Syntec States, and I quote...

"SAE 5W-50: provides the widest range of protection available.

(this one IS dated 9?30/04 tho, i couldn't find the newer one)

six-Speed does have the newer one in his post, and it shows, in writing, that it meets the B-spec. I will keep running that, since i have no issues AND I like Castrol.

Now, seeing as how the WSS number is a part number, and we run the Castrol, are we opening ourselves for warrenty issues? I, personally have the Castrol in ours right now. There is a post on teamshelby that talks about the B spec, and references a phone call to Castrol that the 5W-50 DOES meet B spec, its just not on the bottle.

Seems we as a group have some confusion with this.

I have documentation that says it meets the B-spec. Nothing more needed. If warranty issues come up...I can re-create the documentation because I saved it to my PC.

Although one would think they could update all areas instead of just one PDF.

Could you post a link to that, or post a copy for the rest of us? (oops, nevermind, i saved 6-speeds....... that should be fine if the need ever arises)

Valvoline 5w 50 meets the B spec too:)

Just found out this morning that the Valvoline 5w 50 synthetic is no longer available. Amazing

What filter is everyone using? FRPP or ???? Part Number?

Thanks in advance.

Thanks in advance.
I have used the Motorcraft FL820S filter for every oil change to date; however, I noticed they are making them shorter than the old versions by about 1/4". I prefer the extra volume so from now on I will use the Ford Racing filter. I just ordered two FR filters on-line.

Thanks everyone

Dealership has them for $12.45 just FYI.

I consider myself a little OC when it comes to oils.

I decided against the Castrol after doing some research and finding this link:
http://www.pecuniary.com/newsletters/syntheticsdefined.html

This is the part that I focused on:
The Complaint
Mobil's Position
Mobil contended that Castrol misleads consumers that Syntec is a fully synthetic motor oil despite the fact that Syntec is no longer synthetic. The challenger alleged that after years of manufacturing Syntec with PAO, Castrol replaced the PAO, which had constituted nearly 70% of the volume of the product, with hydroprocessed mineral oil in approximately December 1997. As a result of an independent laboratory test conducted by Savant Inc., Mobil maintained that samples of Syntec purchased in June and December 1997 contained 93% and 80% PAO. Other samples of Syntec, one purchased in December 1997 and four purchased in 1998, contained no PAO, and instead contained 100% mineral oil.

Furthermore, Mobil alleged that Castrol degraded Syntec by substituting hydroprocessed mineral oil for PAO to the detriment of the consumer. Even though Syntec was able to meet the minimum industry standards, Mobil contended that in no way does it prove the current Syntec is as good as it was when it was made with PAO.

It bugs me when companies call their products synthetic when they aren't true synthetics, but they are allowed to do that due to current regulations. I've also decided against certain manufacturers of supposed synthetics for use in diesel engines for the same reasons. Why buy a synthetic blend when you can get a true full synthetic for the same price?

Mobil 1 does NOT have a 5w50 that meets the specs for our engines, and I believe at this point, doesn't have a 5w50 at all any more.

I ended up buying the Motorcraft oil (not sure it's a true full synthetic), but I figured if I had any issues, I'd have a leg to stand on by using the Motorcraft oil. I was able to get it from my dealer for less than the Castrol was selling for locally or online.

Regardless, as long as an oil meets the specs and the API rating, it will not damage an engine. The key is how much the oil and additives break down in how many miles. If you push your oil change intervals, I recommend you do as I do and have oil analyses done to determine the change intervals. It has served me well over the last 10+ years, and it has helped me to determine what are better quality oils. For example, the oil I use in my Powerstroke diesel can go to 15K mile change intervals, though I keep it at the 10k mile plan. I find it cheaper to buy/change one batch of oil and filter at a higher price than to buy/change 3 batches of cheaper oil over the same mileage interval.

However, I am starting at square 1 with the oil for the GT500, and do not have a baseline to provide recommendations yet. If Mobil 1 comes out with a 5w50 that meets the specs, I would be confident in using that, but, I did move away from Mobil synthetics a number of years ago, not because of quality issues, but because of availability issues.

I run Mobil 1 oil filters in most of my stuff, but went with the FRPP filter in the GT500 - similar higher quality filter at around the same price.

I run Schaeffer oils, fuel treatments, etc. in all of my other equipment, but since I couldn't find their 5w50 locally, I would have had to buy a case of 6 gallons directly from them. While that works fine for most of the other fluids I need, since I put so little mileage on my GT500, I would have had a stash of oil sitting around for over 3 years.

Oh yeah, my brother sells Amsoil back east, but since they refuse (last I checked) to allow independent lab testing and certification, I refuse to use any of their products.

Hope this helps.

I just bought some last week, where did you hear that?

got that from the people at roush performance when i called them to order a case of oil. going to use ford motorcraft now.

Just a quick heads up for those that might want to save a buck.

Advance Auto Parts has the Castrol 5W50 Syntec on sale at 5 qts and a Purolator Pure One filter for $24.99 That's $18 off. You can also get $2 off any air filter with this purchase if you need one for this or another car.

Pretty good deal to get the 2 filters free with purchase of the oil.

Advance also give Active Duty military a 10% discount on top of that, for us guys in uniform.

I wonder how many people have the wrong oil in their Shelby...
I had the dealer change the oil in mine when I bought it "used" from a GMC dealer. I called them in the morning to let them know that they needed to call the Ford dealer and get the correct oil and filter. Long story short, as I was signing the paperwork for the oil change, they guy says OK Sir, we installed Motorcraft multi blend 5-30. I said WHAT? Thats the wrong oil! He says, no, sir, we called the dealer and this is what they said to install. I said, dude, look at the oil cap, what does it say there..

Holy crap, I told him he better get that freaking car back in the bay drain the oil, and get his ass to the ford place pronto. Then I was getting crap about having to change out the filter that had the 5-30 in it.

Never assume a thing with the Shelby, everyone thinks its a Mustang, and thats what they probably asked the Ford dealer, what oil is needed for a Mustang 8 cyl

Like I tell the wife, I'm OCD for a reason!!

There are only three oils that meet the WSS*******B spec "in writing" and mobil 1 is NOT one of them. Mobil1 5w 50 is made for european use. The three are Ford motorcraft made and bottled by Conoco,,,Castrol, hard to find here in Texas,and valvoline roush which jack made available on line and then took it away for what reason I do not know and they wont tell you if you call. Even the valvoline oil change places did not know about that oil. And being watchful of dealerships is very necessary because the ford place in Greenville texas did not know that the shelby took a different oil. So with all that it is Ford Motorcraft from now on. If the rest of them want me to use their oil then they need to get on the bandwagon and quit screwin around with me and my $18000.00 engine.:fight:

That's why I only do 2 things:
- change it myself or, if I don't have the time,
- buy the correct oil and filter, and just pay them labor to change it using my supplies.


Nothing else will assure me that some dufus didn't screw up and forget he was working on a GT500 and use the same oil he put in the Focus 10 minutes ago.

Yes Joe ,,that,s exactly how I do it also. Take the oil and filter to my quick lube place that I have been using for years. Pay th labor and it all gets done right.:)

How many miles on new 2010 gt500 before changing the oil for the first time?

How many miles on new 2010 gt500 before changing the oil for the first time?

I changed my factory oil and filter at 1000 miles so I would know exactly what was in the crankcase oil wise. The factory filter is in a plain white wrapper. You have no idea what it is or who made it. Not a letter or number on it. So change it also.

If you bunch of slackers really cared about your cars, you'd spend the $1800 - $2000 for a 4 post residential lift and do your own oil changes. :grinbiginvert:

OK, so I haven't sprung for the lift, yet. So in the mean time, I built some ramps to get the front end up high enough to change the oil, and it was still a tight squeeze, even with the factory springs.

OK bandit,,let us know when you get th lift and we'll all come to your house to change the oil:rofl::rofl:What oil are you using :)pls?

OK bandit,,let us know when you get th lift and we'll all come to your house to change the oil

You know, that's a good idea - I could charge folks $20 to come use the lift the first time, and $15 each time thereafter. You might be onto something here. :cool:

I put in the Motorcraft 5w50 synthetic. We're very limited in our options.

Here's the post I put up earlier in the thread with a little more info:

Don't get too comfortable ... lowers the risk, but not the dufus factor; they can still screw it up. Like striping out the drain plug threads or installing the filter too loose or too tight. I change the oil in all my cars to make sure it's done right. I even go as far as torquing the drain plug to spec, which has been very effective at eliminating any leaks from the pan.

On line castrol's pdf file says in writing that it meets the WSS*****B spec. But try and find the oil here in Texas. Might as well go with Ford motorcraft. A point to heed also is that these synthetic oils are man made and that means they also have DNA. A lab can analyze what you have been using and tell you exactly what it is so do not think you are going to sneak something by Ford on an engine failure due to lubrication failure unless you want some engine pieces stuck up your ass by Ford. OUCH

The Castrol Syntech 5W50 is readily available across Texas at Advance Auto Parts. They often have it on special for $4.99 plus a free Purolator Gold or M1 filter with purchase of 5 qts.

That would be FAR FAR across Texas. There is not an advance auto parts in Dallas or within 50 miles of Dallas. So unless Valvoline wakes up to the fact of missing money it is going to be Ford motorcraft.

Oil??....your supposed to change the oil???

:silly: Howcome nobody tells me about these things!!!!

Same with Checkers, Schuck's, Kragen, or Murray's; your nearest stores are in the El Paso area. Our local Checkers carries Syntech 5W50.

I purchase Motorcraft 5W50 mail order from K-man; got tired of paying over $10/quart at local Ford dealers.

http://k-mansparts.com/items/mustang/filters~fluids/motorcraft-5w-50-full-synthetic-motor-oil-xo-5w50-qgt-quart-xo-5w50-qgt-detail.htm

I get mine from K-man also. Sure hope he stays in business:)

Motorcraft, this is news to me. And, the first change at 500 miles, also news to me.

Took my 2010 in at 2k and had the Ford dealer do the first oil change with Ford Synthetic. Came home had a pool of oil under my car the next day. Put the car on my friends lift and found they dumped oil from the filter on the left frame member. Changed the oil at 4k and put Castrol 5w-50 in myself no oil on the floor and way cheaper. I can't believe Mobil 1 would not be fine too. It goes in the ZR-1 why wouldn't work in a less HP motor...silly.

Motorcraft, this is news to me. And, the first change at 500 miles, also news to me.

You don't have to change oil at 500 or 1000 miles. You can do it at 7500 like the book says if you wish. Those of us that changed the oil early just wanted something different or wanted to know what was in it. Mobil 1 synthetic 5w 50 might meet the ford WSS*****B spec for the shelby but they have NOT said so " IN WRITING" that they meet that spec. Ford motorcraft, Valvoline Roush and Castrol make that statement "IN WRITING" . Now if you want to gamble your $18,000.00 engine go right ahead but if you suffer an oil related engine failure using an oil that does not meet that spec guess where Ford is going to stick that engine,,,OUCH.

I punched in on Mobil's website, and they popped up recommending the 15W50. I'm a Mobil fan and have been running it since I bought the car with no issues. I did print this out from their website though as a backup...

Ultimate Protection
Mobil 1 15W-50
A fully synthetic motor oil, Mobil 1 15W-50 is recommended for high performance vehicles including turbocharged and supercharged engines where a thicker oil film is desired. It provides outstanding performance in high-revving, high-temperature conditions.

I'm not worried about it at all, but if it does blow up, I can play stupid. "You told me it was for my car..." :). I also live in a hot climate, so I'm not worried about the 5w. If it is cool outside, I let it idle for a little bit to warm up. If I lived up north, I'd run the Ford oil, or Castrol. In my mind though, Ford goes to the lowest bidder at the time, so I highly doubt the Motorcraft is the "best" oil for our cars. We all have our preferences though, and every once in a while I try and talk myself into the Ford oil, but I just can't do it... I've used M1 forever, and probably will until they give me a reason not to.

When I first got my shelby I also punched in Mobil1 , very first choice because I have used it for a while also but it did not meet what the owner's manul said to use to keep my warranty valid. The oil cap says 5w-50 not 15-50. I do not understand your comment about Ford going with the lowest bidder at the time. Ford motorcraft oil is and has been made and bottled by Conoco. But it's your choice and I really hope you never have a problem.:)

2008GT500 I agree totally. Mobile 1 is the best oil in the business. Why do you think a Z06, a ZR-1, regular Vettes, all Porsches, Audi's etc recommend Mobile 1. Only manufacturers like BMW and Ford recommend their own oil, geee has something more to do with money then quality. Ford and BMW do not make their own oil.

Wylie, I don't know anything for a fact, just the way big business works. When Ford went out looking for an oil provider to bottle the "Motorcraft" brand, they put it out for the oil companies to bid on. If I had to guess, Conoco was the lowest bid and is locked into that contract for x amount of years. When their contract is up, Ford will put it out to bid again, and the lowest bidder will win. I'm not saying it's bad oil, just in my mind, there is something better.

My local Ford dealership serviced mine last fall with Mobil 1 5W50 full synthetic and simply recommended to use the Ford racing oil filter instead of the standard one. . From my perspective, using any of the main brand of 5W50 synthetic oil will do just fine; pick one and stick to it !! At the end of the day, how you drive the car and do proper servicing will have the biggest impact on the longevity of the motor.

If you're not changing oil in these beasts, at 1k or less, the first oil change, you don't deserve this kind of machinery. Just do this small experiment and you will become a believer. On your first change, get a good magnet and drop it in the oil drain pan and move it around. Now you get to see how much metal a new engine will leave as it breaks in. Be smart or be foolish.:zlurking:

Hate to tell you but Amsoil blows the doors off of Mobile 1, and RP is just as good if not better.

Just because an automaker "recommends" an oil doesn't mean crap, its a marketing thing, to a point.

No where in the owners manual for the shelby does it recommend using any brand of oil. It says to use an oil that meets that WSS****B spec. Only three manufacturers say that in writing. One person says the dealership put mobil 1 5w 50 in their car. That is not ford motor co.,,that is a franchise and the franchise invalidated your warranty and you better hope they stay in business. Use what you want but I strongly urge all the new owners to read your owners manual and go by what it says to the letter at least until your factory warranty expires. I am not against anyone here. I just do not want to see someone get into a pissing contest with fomoco that you will NOT win.:)

Only SVT dealerships will service GT500s in Canada.

Robin took his car to a Ford SVT dealership and had his oil changed, so yes it was Ford that changed the oil in his car with Mobil 1.

I'm sure his receipt will also state that, so his warranty is valid.

Just put 'em on tonight. I went with these rather than the long tube struts because Steedas are out of the way when you want to work on your engine.

I'm happy with mine too. They do their job well. I might paint them some day if I ever paint anything else...

Motorcraft FL-820s vs Ford Racing CM-6731-FL820 Oil Filters

--------------------------------------------------------------------------------

I thought you guys would be interested in reading this comparison study because so many people are under the impression that both of these filters are exactly the same just different labels. Look at the difference in total square inches of filtering media surface, Ford Racing is 250 square inches compared to 156 square inches for the Motorcraft, that's 94 square inches less! A larger filtering surface means more oil flow and greater filtering capacity. I get my Ford Racing filters from LateModel Restoration Supply OIL FILTER, FL820 - HIGH PERFORMANCE MISCFORD for $12.99. The Ford Racing filter is built using thicker metal (noticeably heavier) for the can material and the threaded base plate is real beefy with deep high quality machined threads. I was using the K&N HP-2010 until I read this article. The Motorcraft and Ford Racing Filters both utilize a base end mounted bypass valve instead of a top dome mounted bypass valve like the K&N and Purolator models. You can read about the importance of the bypass valve location in the oil filter comparison link I have attached for you below.

That is some really cool info on the filters ,,, pretty much puts the filter isse to rest

Wow what a long thread ,,,, finally go to the end !
So what I have decided is, that with many of the mods I have done and what many others have as well ,,, the warenty is already toast and I am gonna continue to use the oil I like and change it often but I am going to start always using the Ford Racing CM-6731-FL820 Oil Filter :)

fghtrpilot you like to type. I will order Ford Racing filters shshshsh
