Fuel stabilizer, after the fact.....

[BigJohn]

Old man, neighbor, did a good job of filling 8, five gallon fuel jugs, back when gas was about $3 a gallon. Problem is, he did not utilize a fuel stabilizer and it has been 14 months. I wonder how good the fuel is and mostly, I am wondering if he can add a fuel stabilizer now and if it would make a difference?

It will prevent further degradation, but won't reverse what is already done.

Use Pri-G. It claims to bring bad fuel back from the dead.

"PRI-G goes a step further, actually restoring old fuel to refinery-fresh conditions."

Do you know if it was E0 or E10?

 

[tmorris1]

If it was E0 I wouldn't worry. If E10 and in a decently sealed can, I would mix it into my vehicle a few gallons at a time.

What's done is done, adding stabil will just preserve 14 month old fuel. Maybe splash some 93 in the tanks

Need to rotate them, older ones first. Otherwise it will all be nasty varnish, eventually.

Star Tron Enzyme Fuel Treatment claims that it will "rejuvenate" old gas, but I personally believe that this claim is nonsense.
From what I have personally seen, E10 stored in a gas can for 14 months is old/bad and should not be used. E0 might still be good enough that it can be mixed with fresh fuel a little at a time, like 5 gal mixed with 15 gal of fresh gas in a 20 gal tank, but I wouldn't do this with E10.

E10

Great idea..... add a 5 gallon jug to the 25 gallon tank.

Yep..... good idea....

Thanks for the tip. It was only 2 days ago that I was watching a Prepper YouTube from "Canadian Prepper", where he highly recommended this product. I had never heard of it. Since I am basically out of Sta-Bil, I just ordered some of both varieties....

Pri-G
Pri-D

Since the gas is stored in a five gallon can, I doubt any problems occured. It's much different if it were in a small container or fuel tank on a lawn mower. I would still add the stabilizer. I have used untreated fuel that was a year old and had no problems.

 

[billt460]

Pri-G is more expensive than Sta-Bil, but it's much more concentrated. One bottle of it treats over 500 gallons of fuel. Personally I think it is a better product than Sta-Bil.

I am skeptical about any product that claims to 'restore' fuels to factory fresh.... Noy saying it is impossible, but understanding a bit about the chemistry I'd want some evidence.

Buy a bottle and give it a shot.

I will pass, thanks. Cannot really think of a situation where I would ever need to rejuvenate fuel versus the potential downsides and avgas works great in boats that sit for a few years under restoration

Never seen one that claimed that.. The additive will preserve what you got.

I hadn't either until this from the posts above, I'm not sold for several reasons;

So let's hear them.

I might have to try Pri-G when my stash of StaBil runs out.

I'm thinking that's a bunch of marketing BS, I don't see how adding something would reverse oxidation of the gasoline. Plus part of the problem is that some of the components are of lower molecular weight and can evaporate. They even state the gasoline is not altered, so how do you reverse anything?

Nonsense.
