I think this post should be stickied.
Agreed

Actually, the 5W30 ranked quite a bit higher, and in the "Incredible" category for wear protection... However, it doesn't have that high of a thermal threshold (265* F) so I would prolly only use it on the street. For track I'm actually liking the wear protection and thermal capacity of the 10W30 Amsoil Dominator and 5W30 Joe Gibbs Driven... Just gotta do a bit more research on compatibility and VW requirements.
