The best oil we have found for turbo and high performance engines is Motul engine oil. Its ability to withstand the high oil operating temps of turbo engines for long periods without breaking down, keeps the turbo and engine bearings from being destroyed, thus saving money and winning races.

Motul has worked great for us on the street and track MINIs for years. Get yours today at http://www.sneed4speed.com/brands/Motul-.html We use 0w40 300V in any car that will see hard use and the 5w30 in all others.
