in gasoline powered motors? I keep seeing remarks across this board, but no one has actually said what is the likely effect. Quite a few seem to have starting using it, but is there any long term problem, and is it ok in a turbo assisted motor? Pricewise is it similar to Mobil 1 5w-50, but their other oils are considerably dearer and harder to source. The 5w50 is probably too heavy for my use.
