Re: Oil ?
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.
