Mobil 1 is the "winningest" oil in history. It is also the best selling synthetic oil on the planet right now. You cant go wrong with Mobil 1. If you want to spend $22 a quart on something like Millers, go ahead, but I think that is ridiculous for a street car, or even a race car for that matter. Anything synthetic will perform just fine in a street environment. The only one I'd stay away from is Royal Purple, I've never seen anyone use racing to advertise as much as them, but I cant find where they have actually won anything.
