50:1 gas mixed with 2 cycle marine oil in motor that doesn't mix?

7 posts in this topic

Sorry if this has been asked before, but I just bought a new outboard, and I have the gas tank full from the outboard I was using before. The gas is brand new, and I mixed the oil in before the '85 9.9 motor crapped out on me. So my question is if I can use this mixed gas in my new 96 four stroke 9.9 where the oil and gas aren't mixed?

Thanks for the help!

Dump it in your truck. I wouldn't run it in the outboard.

Lawn Mower gas......

Your lawm mower will burn up that 50:1 without any issues, might smoke a bit, but it wont hurt it. I wouldn't put it in your outboard though.

Agreed. You be be sorry if you it in your outboard. They are a lot more sensitive then your vehicle or lawn mower.

Thanks guys! I was figuring on using it that way, but I thought I should check.

I guess I've never thought it would bother it at all. First, the spark is much hotter today than it was in 1985 insuring more responsive ignition and more complete combustion. Second, 50:1 is pretty light oil raio and I would have guessed the engine wouldn't care less. I've run mixed gasoline in motors all the time without issue. I figure the added lubricant doesn't hurt either.

I've never actually tried it and I'm not a mechanic so maybe I'm wrong but I personally wouldn't hesitate to try it. If you're really concerned you could mix it 50:50 with raw gas until you've used it up.
