Reply To: What to do with old gas?

[David Stanton]

As long as you know the gas/oil mix, and it has no ethanol or ethanol has not phase-separated, I’d use it in your old outboards. I’m in Minnesota and I routinely keep ethanol-free, oil-mixed, gas over the winter and use it the next season – no problems, no stabilizers. I make sure it is not just a little bit in a big tank, as gas can evaporate leaving a heavier oil mix behind. Never had a problem.
