Oil for 1978 Mercury 1150??

[johnson1]

Can anyone out there tell me if I HAVE to use Mercury two cycle oil or can I use any good oil for my mixture. They guy that sold me the boat said the Merc motors (outboards) required "Merc" oil. Am I safe to use another brand? <br /><br />This may have just been a marketing deal for Merc, but I wanted to make sure. Thanks

Does he own stock in Merc? Seriously though I have used the Shell (low smoke) 2 stroke oil for the last 5 years in my 1976 Merc 1500 and it's still running fine

Hi, Johnson.<br /><br />Merc and Yammy employees and fans are fond of telling people that "you gotta use" their brand of TC-W3 outboard oil.<br /><br />Not so. Any TC-W3 rated outboard oil will work just fine.<br /><br />If you want to read a debate on the subject, check the thread, "2 stroke oil is 2 stroke oil, is 2 stroke oil" .

Thanks! Yeah, I think he was suckered into thinking that he had to use Merc for some reason. I actually have some really good Havoline I have been using. Little spendy, but does the trick.
