Well if you drive hard, the engine will run hotter and cleaner.

My N54 ran amazing, and didnt really have much problems. But we had plenty of people come in with 535s (generally an older driver) with many fuel system problems, injector problems, carbon build up.

I tracked my 335i, so it was getting driven quite hard, guess even though I was using it to its full abilities, I was saving its life!
