Run it in your lawnmower or snowblower or any other 2 smoke engine. Maybe add a cap-full of sta-bil to it. It will work fine.

You can cut it by 50% with new gas and burn it in your lawn mower, weed whacker ect.

Or, if you have one near by, you could take it to a recyling center.

How much do you have? If you have a 1/2 tank in the boat then fill it up with 93 octane and new oil and run it, just don't run it WOT. When it gets down to a 1/2 tank again fill it up and she is good. One weekend with the old biggie. I just ran out about 65gallons of 2 year old(was 93 octane) gas in my boat the same biggie.

Well I say that but does it still smell like gas or is it vinegar gas?

I dilute it ( 50:1 to 500:1 ) in my 82 S-10 BUT... I'm in FL with a 2001 Taurus ( more engine computer stuff I don't understand).

Will it cause a problem for the Taurus?

I can give it to a neighbor, but @ $ 3.40.......

any info would be appreciated!

2.5 years? Do you know if it's E-10 gas? If so, run it in something easy to repair like a lawnmower or weed-eater just in case. If not, just give it a good shake and use it in your boat. Assuming, of course, that you have a fuel-water separator and don't go 50 miles offshore.

Nah won't hurt anything...I ran pre-mix in my 2004 GTO to get rid of the 25 gals I had. I used one 5 gal can to each fill(18.5 gal tank?), never a puff of smoke or anything weird. I also ran it in my lawn tractor.

If anyone has old 2 stroke oil that they are affraid to use or can't anymore because they now run a DFI. Use it in your diesel car/truck at about 3-4 ounces for every 15 gals. It is proven that the extra lubricity will improve your MPG due to the less slippery 15ppm diesel we now have at the pumps. I have been using it now for 2 tanks and I went up about 1mpg.

Old thread but a good topic to review. Here in Jacksonville the city has a hazardous waste drop off facility. They accept anything from old paint to computer hardware. I dropped off 12 gallons of 3 year old gas and the rotted fuel tank it was in. I would think that most medium sized cities would offer the same type of drop off location.

Most lawnmowers for the last MANY years are four-stroke. I
bought my first gas lawnmower about 1982. It was a four-stroke.

I think sta-bil (sp?) needs to be added BEFORE aging.

Most string trimmers are still two stroke. Don't just cut it
and run it. Maybe 1 part old premix, 3 parts new premix. But
you gotta whack a LOTTA weeds. I go through maybe 2-3 gallons
of premix in my garden stuff on a half acre. Most of it goes
through my leaf blower. About 16 oz goes through the Stihl
string trimmer (Weed-whacker is somebody else's trademark).

I have a toyota tacoma that I pour my old gas into when I fill it up. Pour it in, then fill up. I never really let it get that old though. Usually 6 months to a year max.

Modern car engines are amazingly good at digesting just about any crap that passes as gas these days. Not sure why four-stroke EFI outboards, which are petty much the same idea (computer-controlled, sensors eveywhere, etc) seem to be more finicky.

I run the old pre mix through my fifty (50) year old John Deere two cylinder gas farm tractor.

That machine loves the pre mix. In fact, I add several ounces of two cycle oil to each ten (10) gallon fill up.

It's good for the valves and other parts missing the lead from yesteryear.

According to my internet research use a ratio of 5:1 new gas to old gas and burn it in your car. I have done this without problems.

We have a waste oil furnace at work that is great for burning old gasoline.

Like Firebrand I find and old motor to run it in. Latest victim is a 70's VW bug with 6:1 compression and the need for lead it is perfect.
