I’m mad. My neighbor asked me if I wanted a small plastic drum, 22 1/2 gallons is what they are I think. It probably had something nasty in it so no good for water so I told him no and he tossed it in the burn pile. Two days later I had a thought. I could have fit a whole summer’s worth of diesel in it for my little tractor.
I’ve got 55 gallon plastic drums but storing gasoline is a little risky and I wouldn’t use that much diesel before it went bad. Lots of air space will help it go bad faster too. I might go buy a couple of proper 5 gallon jugs, yellow for diesel and red for gas. I do have a couple of old gas tanks from vehicles but I’d have to peak inside and make sure their not rusty.
Yeah gasoline doesn’t keep very well.
I think diesel has a good shelf life if you put the proper additives in. I used to work at Allison, we had to put a biocide in our automatic transmissions because if they sat in inventory a long time, you could get algae growing in the lube oil. Diesel can do the same thing.
