The past few times i have started my generator, a black carbon like stuff comes out. It doesnt seem to be oil because i touched it and it did not seem slick or anything. It goes away after a few minutes, but it is very annoying and bothers me. Someone said i might have a small oil leak and when...
alright so a buddy of mine is looking to chane his engine oil. he has twin 7.4L mercruisers. what kind of synthetic oil do most of you use or prefer?
thanks
