I've been building engines for over 30 years, including go-carts and motorcycle engines. After stripping down many cart engines I can see the difference that Mobil 1 makes to an engine. Norm Wright (a Brisbane based Go Cart champ) has a front running go-cart that has won 3 years consecutively, and Mobil 1 is a major factor that helped. While stripping his engine, I have found that the internals of his engine are still within performance specs and with very minimal wear.

I only recommend one engine oil and that is Mobil 1.
