I've always wondered what the average consumer, such as you and I, would really expect to find for "problems" when we're only talking about particles. I just try to make the best choice I can, but figure that I may never see any tangible difference.
Agreed. I guess the only 'problems' the average consumer might notice would be from over-oiling, and that's probably only an issue in newer vehicles. The exception would be turbocharged engines, as MC387 said.
Of course, no matter what type is used, it will need to be changed/cleaned as necessary.
