Now that we have our new 4-stroke engine, I have about 10 gallons of pre-mix left in two of my tanks. I gave away as much as I could to the folks who bought my San Juan 21 and it's 2-stroke, but that was only three gallons or so. I can't pour it down the drain, I haven't been able to give it away, now I'm not sure what to do. I've thought about pouring it into a bucket to let it evaporate, but that doesn't seem like a good plan, plus I'd still be left with the oil afterwards. I might be able to give it away at my marina, but that's 30 miles away and four gallons of $4.50/gallon diesel there & back, hardly a win. Plus the gas is all ethanol mixed (or at least I'm pretty sure it is). It's been treated with Stabil, but it's at least 5-6 months old at best.

Ideas?

Nest time you see a landscaper in the neighborhood, make his day and give him gas for his trim tools.

I pour my unused mix in my truck (a gallon or two per fill-up) and use it. At almost $4 a gallon it's liquid gold.

Three suggestions:

I leave things I don't want anymore on the corner. I live in the city in a residential area. Last summer we had a garage sale and there was a bunch of stuff we could not give away. So I put it out there on the end of the street, on the corner and it was gone by morning.

At the end of my sailing season I empty my gas tank and take it to one our local fire halls. In a city with about 30 firehalls, about ten of them accept hazardous waste, such as paint and used oil and gas etc.
You could also call a sea-cadets or boy scouts group -they often have older OBs.

Thanks for the ideas guys. The landscaper idea is good, I think ours shows up today or maybe tomorrow, not sure. I also like the Sea Cadets idea, except they're just as far away as my marina. I don't want to get rid of the containers themselves, just what's in them. And both of my vehicles are diesels, so I can't pour it into their tanks. Guess I could also offer it free on Craigslist, but that can be a hassle as well.

David,

I bought my four stroke in '05 and had a six gallon tank of two stroke fuel left over. I also have several two stroke tools about the property that have been using that fuel without problems. Just noticed yesterday that I'm down to the last gallon. All fuel is STABILized and after 3 years working as new on chain saws, weed wackers, leaf blowers, all one cylinder units very demanding of fuels used. So that's one option. I've heard of others, here, that recommend using it in autos, but the auto manufacturers claim it will foul catalytic converters...not a good deal given the cost of replacement of those units. You'd probably get away using it in older cars/trucks.

If you're local I'll take it

I always emptied the tank at the end of the season into the rental truck or van that I used to cary all of her cushions, sails, etc. home in. We had a 4 stroke on our C25, but I never wanted to save the fuel from one season to the next. We had a 2 stroke dinghy motor and we would pour that fuel into the rental vehicle as well. The amount of oil in the fuel is so minimal that even a few gallons worth won't harm anything when mixed with regular gas in a 20 gal fuel tank.

I've put pre-mix in my minivan without problems, in very small quantities. Like above, consider garden equipment such as trimmers, chain saws, etc. Also, if you have friends at the marina with 2 stroke motors, you could distribute it among them.

"I pour my unused mix in my truck (a gallon or two per fill-up) "

Shouldn't hurt a thing. A gallon of 50:1 premix diluted into another 15 gallons doesn't make for much oil in the fuel.

Well, my landscaper was "very happy" to receive the free pre-mixed gas. There's a bit of a language barrier, so it took some pantomiming and lots of pointing to indicate that he could have the pre-mix, but not the un mixed gas. After filling his pre-mix jerry can, I drained my main tank nearly dry into my spare tank, and told him he could have everything in the spare tank but not to take the tank itself next time he comes. I think he understands...

At least now I can fill my main tank with nice fresh gas to run in the new engine.

Thanks for all the suggestions guys.
