New treatment option for old gas?

[mik0524]

Hello, Has anyone here heard of a newer process or procedure for treating old gasoline making it useable again. A co-worker said he heard of something where the gas is pumped through a filter and treated with addatives making it good again. I know, i know, Yeah, right. I thought the same thing i'm familiar with a similar sounding procedure of running diesel through a filter and pressure cleaning tank but never gasoline. Can you polish gasoline similarly? My search online only turned up what is commonly known on the subject and was not able to find an option involving treatment . Again, i'm skeptical but figured it's worth a shot asking here as I have about 120 gal of 5yr old gas to deal with and if theres an option out there other than pumping out and paying for disposal I'd like to hear about it. Thanks to all who take their time to contribute their experience and knowledg here. This forum is a great resource for all boaters and y'all are much appreciated.

Its dead. Pump it out. Disposal is about $0.75 per pound.

Yeah, thats what I figure. So are you saying there is no other option or this the best option? Because this is about what id be looking at. 1 gal = appox 13 lbs x 120gal= 1560 lbs / $0.75 lb = $2,080.00 disposal alone + replace gas cost 120 gal @ $3.50 gal about $420= we're talking over $2,500.

Gasoline fuel polishing removes contaminants but can’t “refresh” the fuel.

It worked out well for the two guys i know that had it done.

How old is the fuel?

If you can revive 3 month old rotted road kill to a live animal, only then can you bring back fuel that has gone bad.

Use it as bonfire fuel

What am I missing? Is that new math?

Gas is 6lbs/gal not 13lbs

Using your stated 13lbs/gal at $0.75/lb to dispose, the cost is 3/4 of a dollar... so LESS then the weight in lbs in dollars, not more then a dollar per pound.... 1560lbs into $2080... using 13lbs/gal thats $1200, not $2080....

Still a bit expensive using accurate figures, but less then your stated $2080.....much less in fact..... $540+/-.....

Allowing for exchange into Canuck$, still less then $1K.....

Same for diesel instead of gas.... $640+/-... Changed to Canuck$ sub $1K also

The gas is over 5 years old. Prolly closer to 6. I was hoping there was something new out there that i hadn't heard of but doesnt seem so. Thanks for the input guys. Oh, and Ignore my math above 1 gal gas doesnt weigh 13 lbs, I dont know what i was thinking there. Regardless, still gonna be expensive Just trying to save wherever I can ....cuz the fun part, twin evinrude 150's, is still to come. Who knows what I'll be looking at when I get into them. Shame, Motors are 2000's with less than 400 hrs

u right JB

Gas is 6.82 #/gallon

Fuel has a life expectancy of 6 months. Not a thing can be done to save 6 year old fuel

However your fuel tank is vented, so I doubt you have 120 gallons left after 5 years. My guess, you have 20 gallons of goo, and your tank needs serious cleaning

If the fuel still smells like fuel, and not something closer to varnish, you may luck out.

Mix it with enough used oil that it can be used for burning yard debris and have a bon fire. Thats about the best use for it. Or pour it in your exes gas tank.

I agree. Mix some with fresh fuel in your vehicles and use it.

I ran 20 gallons of 10 year old fuel years ago ( 1998 era gas ) in my lawn tractor. the 1951 Chevy I pumped it out of ran fine on it too

I can see your point, 120 gal of fuel down the drain so to speak would be a bitter pill to swallow. Converting it to liters that's $520. If it were me I would try it in the lawn mower, if it works and smells like gas you could mix it with fresh gas and try it in your car, use a gallon or three with every fill up. I might not want to try it in the boat. I hate paddling my boat into shore. Its like the walk of shame, lol

 

[Scott Danforth]

after 5 years with an open fuel vent, I doubt there is 120 gallons left in the tank.

Stick your nose in and smell it, you never know. I fired up gas pole saw this fall that I didn't even know I had! Was my dads, tucked into the back corner of a shed, and had been at least 5 years since it had been touched. Gas still smelled like gas, a couple hits of the primer, and it started right up!

2-stroke oil will help keep gas a bit longer.
