I still have doubts about the super wide range oils like the ones that seem to be popular in Europe.
I guess their oil analysis results have been good, but how do these oils perform in a high rpm engine that is driven hard? I just don't see how they could perform as well due to the increased use of VII. Am I just stuck with the old school way of thinking. Are these oils really just as good or better in terms of being shear stable?
