Re: Fuel additives?safe?
i'm not a 100% sure on this but, seafoam is a cleaner and you put oil in the gas to lubrcate the internals. it would seam to me that the seafoam would dilute or make ineffective the oil or take away its lubricity thus really messing up an engine. if you try it let us know how it worked out. or better yet call the company that makes seafoam and ask them.
