I have signed up for this Pennzoil deal, and it is actually legit! To my surprise. I do not know what oil was in the vehicle up to this point, but the Pennzoil 5w40 that I received definitely made it feel just a hair smoother and quieter. Makes me wonder if appropriate oil was used in the engine or not... Sent it off for a UOA, waiting on results now. Is it possible to guess the manufacturer of the oil by the UOA?
Need an oil recommendation.
