Well, depends. Royal Purple rocks for oil. But it has a cleaning agent in it that keeps the internals of the engine clean. Well if you think about it, that will eventually not be good for it. Alot of people have run Royal purple for many many years, and alot of the se-r guys praise it. But for the price, MOBIL 1 is as good. Personally I would just use Mobil 1, and not waste the money on Royal Purple unless your car is gonna go through some serious abuse as race cars do.

You can't go wrong with synthetic. I use redline in the engine, trans, and power steering. I change oil every 4k mi and blow a fifty every time but nothing is too good for my car. For most people though, mobile oil is great and costs half as much. Any of you supercharged guys better be running some kind of synthetic since your sc bearings are lubed by engine oil and they run a lot faster than 6500rpm!!
