quote:Best thing you could do is have a UOA done and see how it has been working thus far. IMO, for the cost of a Quickie Lube change a UOA is money well spent! Based on results here I'd say it'll probably be fine into the higher mileage arena but a UOA will let you know for sure how it has done up till now. Once the vehicles gets up there in miles you can always switch to a heavier weight oil if needed. Mikep

Originally posted by Alex D: I've said it and say it again. After trying many oils in my Ford modular engine, Amsoil S2000 0W-30 is the best oil I had in there so far by a long shot.
