I have a '04 150L Mercury EFI which I recently bought. The shop were I bought it said if I didn't run the Mercury Premium Plus oil I'd void the warranty. The oil runs about $26/ gallon at their shop, but I've seen other TC-3W oil for as cheap as $5/gallon. Does it hurt to run with a different brand oil? Every company has their propaganda I realize that. Quicksilver says there's is the best and has out performed Mercury oil in lab tests but Mercury says theirs is better. I've seen the Penzoil and Johnson's Brand say about the same and now I'm confused. Am I taking a risk if I run the cheaper TC-3W? What do you guys think?
