I wouldn't bother treating it now. Filter some and try it in a mower. If it works there, maybe filter some more and add a couple gallons at a time to your vehicles until its gone.

wouldn't chance it now....but if the SHTF.....I might dilute other gas with old filtered gas....but I don't want to chance it in a motor that I may have to rely on with good gas avialable.....just me.

The only way to keep gas long term is sealed and cold. Once the aromatics wander off, it's turpentine.

Well now I am trying to figure out what to do with it. Use it like "Hamburger Helper". Thoroughly mix one part old gas with 10 parts fresh gas, and run it in your vehicles. I've even mixed 12-year-old gas with fresh gas at a 1:4 ratio, and my pickup likes it just fine. |

Last time I tried to run anything on over the hill gas, it was leaded gas and a '68 Oldsmobile, and it wouldn't run at all. |

I agree, old, varnished gas won't "still burn, but you will have a hell of a knock", it just plain won't burn. |

PRI G WILL restore old gas.
Was the gas well sealed? If so, it may still be fine by itself. I'd treat it with PRI G and I would probably double dose it....although that might be overkill. I'd then try it in a mower or something cheap. If it runs fine, I'd run it through your car. For piece of mind I'd probably put 1 can per tank and top off the rest of the way with fresh gas. But, if the gas is even remotely decent, PRI G will restore it. |

It really depends if the gas was sealed well in an oxygen impermeable container.
If oxygen got it, then you'll have some oxidized hydrocarbons that will varnish out. Give it a good smell....that will be the tell.... If it smells good, then dilute and use. It it lacks a bite, then lighter fractions and aromatics are gone. Addition of toluene, naphthalene, etc might refresh it. It is stale and offensive to smell, then I'd avoid using it in motor vehicles that you care about. If you're handy, run it in a machine with a simple carburetor that will come apart and clean easily if it varnishes up on you. Or you could used it for 'burn gas. |

It is stored in the standard 5 gallon plastic containers. I think I will treat one container with PRI-G and give it a go. I will experiment to see if I can restore it. That way I will know for the future .

I had a 78 oldsmobile station wagon as a hand me down car and it ate anything resembling gas until I totaled it.
It had a 350 olds engine and the compression was 7.8:1 I think. It was low I know that. I treat gas mowers about the same as I treated that car, I might mix old and new together but it would run on about anything. Might need to change the fuel filter more often but it always ran fine since it had such low compression. Some generators get treated in a similar fashion, my cheapy coleman 2500 watt gets treated that way but the honda sips gas so it gets decent gas. I only buy 100% gas, have a local station nearby, so I don't mind mixed old stuff up very much. |

One thing Im going to miss about my old f134 engine in my jeep , that thing would almost run on a drop of jack Danial's in a barrel of water . I have dumped all sorts of crud in that thing and it never made much difference . I doubt the 4.3 will be so forgiving .
With that said just blend a little in every now and then being carfull not to stir it up ,then dump the last inch or so . |
