Wal-Mart has it too, cheap! Especially in the 4L jugs. CT sometimes has it on sale to every once in a while.

I thought the Mobil-1 doesn't meet the Ford -B spec. Ford specifically changed from the -A to a new -B spec based on what they learned on the F-GT (or so I've read) so, if not a big cost diff, I'd go for the -B spec.
-lol.

I don't think Mobil-1 5W50 meets the Ford WSS-M2C931-B spec -- it's more than SAE and weights ...it includes specific additive groups and reduced levels of other byproducts. Only if it says "Meets Ford WSS-M2C931-B" on the label are sure it does and was tested to that spec, imo.

What about the Castrol Syntec 5W-50. Does this meet the B-Spec ?

I was told by a Ford tech that it does ...but it doesn't say so on the label so I'm skeptical. A fellow on another forum also says it does but that it just hasn't been certed ...dunno.

I use Castrol because it is easy to get and cheap. I change my oil much more frequent than needed so I'm not worried about the 'a' or 'b' thing.
There is hardly any breakdown in the oil when I change it and the filter....about every 3,000 miles or before and after track time and dyno time which ever comes first.

But I'm with the wise Bird here; I drive and ride all my stuff hard, so I have always changed oil often. Every 4000 Miles in the Shelby and every 2000 miles on the streetbikes every 30 hours on the Motocrossers. It is probably not the most environmentally friendly way to maintain an engine, but fresh quality oil on a regular basis is cheap insurance IMO.
