Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Pro's and Cons of Mobil 1Syn???????

many of the people on here are trying to get every bit of performance out of their cars as they can (w/o turning them into full drag cars). i'm sure completely switching to synthetic will give you some gains, but on an engine with less than 200hp, it's not gonna show much, but still worth it.
