Re: oil on top of piston? what does that mean? (DuNkiN)
how do you know there is oil on your piston? Did you look through your spark plug hole? If you see black deposits, that is normal. All piston tops will accumulate slight carbon deposits. Run a fuel additive through your motor preferably Regan by Penzoil. About you losing oil, it might be your rings, or your avle seals. Try going with a thicker oil.
