got about 8 gallon of regular gas in portable tanks of a fishing boat that hasn't been used in about 3 yrs. does not have oil in it. Any additives to rejuvinate that aren't snake oil? Thanks

I would probably slowly add it to my vehicle. Like 2 gallons one week… 2 gallons next week, etc.

I just gave the above advice to a friend of mine with 15 gallons of gas a few years old kept for his generator.

that's kind of what I'm thinking. Just not worth the risk.

I'd see if I could bring it to one of those haz material recycle places, but then I hate transporting gas unless it's in a really good container.

Yeah, lawn mower if you feel you have to. Otherwise, you got 8 gallons of marginal weed killer and that's about it. Maybe save some for burning leaves in the fall or use it on your spring pickup brush pile.

If it was purchased at a marina it is most likely ethanol free. Stored in closed container it is probably OK.

Does it still smell like gas or like varnish, it could be ethanol free, depending on where it was bought.

You could add it to your lawn mower a little at a time, if it still seems fresh.

I'd call these guys Louisville Haz Mat Disposal

Similar to the OP's question, only I have about 9 gallons of gas mixed for a two cycle boat motor that has been sitting in an onboard tank for 3-4 years. I'm not sure if I used 10% ethanol or regular gas when I filled it.

I'm curious if the 2-cycle mix would keep the gas from degrading.

Ethanol is the problem. It degrades and gums up carburetors. Without ethanol gas keeps for a pretty long period of time.

A lawn mower carburetor has a hole about the size of a pin. They gum up easily. Then the carburetor has to be removed, taken apart, and cleaned.

I keep small amounts of contaminated gas (a gallon or two) for burning leaves and other junk in the yard. With 8 gallons, I would probably take most of it to the haz mat disposal in town.

If you are sure it hasn't been contaminated with water, you might try dumping in some octane booster and running it in power equipment in small quantities to dilute it.

If it does not smell bad I would add some of that enzyme stuff, cannot remember its name right now. Not too expensive and put it in a car or pickup and run it. Won't hurt a thing. If it has a nasty smaell to it (unlikely). Then dispose of it. Simple as that.

I put the 2+ year old gas i took out of a boat and used it in my truck. About 50 mile after a fill up i would add 2 gallons of it the truck. Did not have any issues.
This was ethanol free gas with some seafoam additive in it.
If you do use it make sure there isn’t any water in it.

Nope. You cannot "rejuvenate" gasoline.

If it's adulterated with ethanol it may be questionable. Ethanol is subject to phase separation. Once that happens what you have is unusable hazardous waste.

If it's pure gas, aka: "recreational gas," it is very likely ok.

For God's sake, please don't do that. Gasoline is full of no end of persistent biohazardous chemicals.

Not true. Last I knew, all the marinas around here were selling ethanol-adulterated gasoline. (Surprised the hell out of me.)

Nope.

Being as doublesharp is in the Louisville area, his gasoline has a better chance of having survived than your's, you being in cold country. It is temperature extremes that often provokes phase separation.

I wouldn't put three-four year old ethanol-adulterated gasoline in either my vehicles or my lawn equipment. I would take it to a hazardous material disposal facility.

Phase-separated ethanol-adulterated gasoline has been known to destroy engines--depending upon just how it phase-separated. Sometimes, when it phase-separates, one phase is essentially pure water. Imagine an engine running at speed all-of-a-sudden getting fed nothing but pure water.

I agree with those saying if it smells like gas use it, but if it smells like varnish, don’t use it. I mix it 2-3 gallons at a time with fresh gas for the rest of the tank in the car. Rec gas though only. All the marinas I’ve been to sell Rec gas, including Rogers City Marina.

Startron Good stuff. A few gallons at a time in the car is what I would do with it.

This is why everyone needs a milsurp drip style gasoline water heater. Use the old stuff while camping to heat water in a metal trashcan.
