I tried this in the oil forum and did not get much response so I will try it here. We have all read a book or two concerning different types of oil and what they do for an engine. I agree that there is a better quality of oil for almost every application and the properties can be a lot different for whatever reason. But has anyone ever had an increase in power from oil. The discussion came about because of an article stating that their oil removed the poly from the cylinder walls allowing the rings to seat better. I did hear another conversation on this once before and blew it off. I could see if a lighter oil was used so there would not be as much restriction but how about oils with the same weight for a particular application but with different properties?
