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.

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.
