Re: Synthetic Oil ?

Sure, as long as it meets Mercruiser's specs. But you won't derive much benefit from it. One of the benefits of synthetics in cars is extended drain intervals. However, in a marine environment, you still need to follow the same oil change schedule since the oil is subject to greater contamination.

i put Amsoil 100% synthetic in mine. I change it once a year regardless of how little it is used. I swear by it, and want the best for the only engine I have for my boat lol.
