    Will diesel fuel stored in a 55 gallon drum still be good after 15 years?

    It may have an algae build up... I would say NO

    Look at propane (LP). I just used some left on a farm I bought 20 years ago. By the markings on the tank we figured it was at least 35 years old. Good motor fuel, heat, etc.

    It really depends on a number of factors, and what your intended use is for it now?

    IF the drum was sealed when fresh and the fuel had been treated with one of the diesel biocides and not stored in extreme cold, it may be salvageable. Check the insides of the drum for slime and sludge and, if possible, drain (from the bottom) to remove all separated water.

    I've used Aviation fuel stored in just this fashion that was sitting in the tropics for 6 years. We treated the drums with Biobor JF upon opening and double filtered as it was pumped, but we didn't have any problems with it.

    We ran small turbine generators with it, I don't think any of us would have wanted to fly with it. But, I never heard that it did any harm to the generators.

    There may even be better products out there now to help you recover it? Cost considerations also enter the factors.

    It can be cleaned or polished. Large diesel boats that stay moored a lot have their fuel polished once a year.

    I wouldn't use it. Can cause algae and mold in fuel tanks. I have know people who used old Diesel in tehri Motorhomes and they end up geetting mold in the fuel tank and eventually causes problems and have to have lines, tank etec. cleaned.
    If you use it, be sure you have lot of filters.

    They must put something in off road diesel, because I have a bunch of old John Deere's that run on it and some of it is at least 10 yrs old

    I know nothing about diese fuel or engines. Why does it accumulate all this stuff? What does it mean to "polish" the fuel? Thanks

    Yip! Just soak a couple of tires in it and you'll have one dandy of a fire for your next brush/fence row clean-up.

    I wouldn't use it in any of my equipement. It might work and it might not, why take a chance of clogging an injector? Fuel is cheaper than engines. If you are bent on trying it I would mix it with fresh. I was told by a mechanic the new bio diesel fuel will grow mold, in just a few months, didn't know the old stuff was prone to do it too.

    If it was mine I would save it for this winter and use it in the trap clubs outside salamander heater.

    Or mix it with fertlizer and have one hell of a 4th of July bangup party!LOL

    Depends a lot on what you want to use it in.......an old Cat dozer will burn about just about anything you can pour in the tank.......A new common rail Duramax would be a very bad system to try it in. Modern diesels are designed to operate with next to sterile fuel,...... turbine generators, old ships, etc. cannot be compared to current diesel technology. Some filtration systems on new diesels are in the.... single digit "Micron" range.

    I'd have to be damned desperate to even consider it.

    Take a sample to a fuel distributor and have it tested.

    Mix it with waste oil/atf and burn it in a waste oil heater for heat! It would also work in a kerosene type heater or kerosene lamps. Put poor fuel in a new high tech diesel these days and it can be costly to get it right again. Don't get caught with "Off Road" diesel in an "On Road" vehicle. Manufacturers can void warranties and the "Authorities" can give you a bad case of heartburn and empty wallet syndrome. I use Kerosene and clean diesel to soak and clean trigger assemblies with.

    You might possibly filter it well and dump in some additives. It might run well or might not. Cutting it with fresh diesel and/or kero as the weather requires, might allow you to burn it up.

    As one person said save it when you have a bush pile to burn. That is your best choice.

    Cripes, my pickup sat mostly unused this winter and most of the spring. Didn't even use a half a tank of gas. It decomposed into crap that reminded me of shellac, and stunk like it. White smoke coming out the exhaust, it looked like a very dark amber color in the fuel filter, like a dark beer. Siphoned out about 10 gallons and replaced it with fresh gas. Truck runs fine now. Dunno what I'm going to do with 10 gallons of bad gas.

    Polishing fuel is simply pumping, fuel thru a series of ever descending fuel filters---1st 30 micron, 2nd 10 micron & final 2 micron--

    If it was gas and "oxygenated" using alcohol products, it could deteriorate rather quickly. It can do damage to older vehicles as well. Seems to me that this crap has a short shelf life, besides giving you a significant reduction in fuel economy.

    Even if the fuel has been stored in a such a way that it has not deteriorated
    15 year old diesel oil would have way too much sulfur for an engine built in the last few years. The current max is 15PPM sulpher. 15 year of fuel could be as high as 5000 ppm sulphur.

    My fuel supplier always cautioned me to never order more diesel than I could use in a year...

    If it is in a steel drum than no light got to it, but if it was exposed to changing temps it could of collected water and rust from the drum. If it was exposed to sunlight it would likely have alge in it. If you don't have a way to filter it before you use it save your self the hassle. New trucks you plug the filters one drum of it wouldn't save you any money plus a possiblity of much hassels. We did did up an old fuel tank at a truck stop it had fuel left in it for over ten years. Pumped it out trough a filter and my 99 7.3 went from 16 to 19 mpg sulfur and the way they crack it now it had way more power in it then todays fuel.
