Grabbed a jug for 13.50 at Walmart. Use to run Castrol 10 years ago so thought I would try it again for no particular reason really. It runs great..no different than any of the other brands I've run. On the back it states it is GM and Ford approved with a serious of numbers following it, and not sure what that means. But it says nothing about Crysler. Any particular reason it is only those two companies they list? Any UOA and VOA's on this new formula?
