Hm, since the topic is ''oil''......I wouldnt call this a ''gain'' or anything, but after i put new oil in my car, it revved up a LOT higher....cuz, before, it only went up to ~5 or 6 thousand before shiftin...Now, it goes complete redline, gets up there quicker, and stays up there for a lot longer of a time before goin to the next gear....Feels like a new car!
