    I would think if the container is sealed air tight and gas occupies all the volume it will never go bad. I do not think the caps on a 5 gallon container are air tight.

    I have always stored gasoline, diesel, and kerosene, keeping 6 months to two years supply on hand in 55 gallon drums, buying a little more when it is cheaper and buying less when it goes up, keeping my rotating stock within those supply parameters.

    A few years ago I wanted to experiment to see how long I can store gas under those conditions so I sealed a handful of drums and set them back. They are in an open shed in deep shade stored off the ground.

    I opened one at two years, three, and now four. Gas when stored was whatever I bought (winter or summer) and no stabilizer was added. The drums were filled to within a couple of inches and sealed.

    Just cracked one from four years ago yesterday and it looked and smelled like the day I put it in. Put 3 gallons in a generator and it fired right up, no issues. Given my experience with years two and three I was unsurprised.

    I have two more sealed from then, so the experiment continues.

    I also have one that was left with the bung off from two years ago. Every now and then I siphon off a gallon or so and inspect it. It's starting to turn a little darker and smell a little different, but the generator still runs it fine.

    I remember you mentioning your fuel storage thing a good while back, and that's one of the reasons that I picked up a couple of new steel drums for bulk kerosene storage.

    Kudos to you on a real-life test. You'll find a million-and-one opinions about stuff on the internet, mostly by folks who don't really know, but very darn few opinions based on actual testing of the idea. Please keep us informed as you learn more.

    I'm keeping my kerosene in my garage, but for obvious reasons I don't plan to keep a couple of hundred gallons of gasoline in there. When I get a stand-alone building on my place set up, I plan to start my own gasoline storage system, and I welcome the knowledge.
    Is it me? It's them, right?

    Yup, the better sealed and less air in the container the longer the gas will last. Bad gas from age is largely from the lighter components evaporating off. In a sealed container kept coolish, it'll evaporate until it reaches the vapor pressure then stop. There's a small amount of degradation from the larger molecules breaking down but a lot less than the light stuff evaporating. That also means if you open it to check it, you've reset the process.

    Depends on the can. I bought new spouts from Rural King and they are.

    I found that the 5 gallon Poly containers we used when we were racing are very air tight. The lids have a decent seal and the air vents are very tight as well.
    I have these stashed in several locations. Some for over a year possibly 2. This thread has me numbering them and starting a rotation log.
    When gas prices fall I will fill the trucks from the older stores and refill them.

    Bingo.
    I'm looking at some Jerry cans. Found some used for $45ea/1 $40ea/4. The poly cans aren't fond of sunlight and I keep one in my truck as the fuel sender doesn't sit as low as it should.

    I keep all the poly inside in remote shaded places.

    Sorry there Lee11b - WD40 is fish oil base, not petroleum. Still oily though.
