Sometimes we have those little epiphanies in the shower.. sometimes they come from other places. This is a home for those epiphanies.

Can only do so much with one tank, though. IDK how smart it would be to keep a tank or barrel of fuel in your garage ...
I've considered similar with food, but most of the food I eat is either perishable or has low value per volume, and I have limited storage space. I did stock up on cheese, though.
yeah i was thinking about getting jerry cans out to the station but i think it would only be another car tank worth at most to hold out for oil crisis to come down, for that that little i probably should but idk at what volume you should stop at.
foods probably gonna be the same situation because sulfur from oil wells somehow intertwined itself chicken husbandry.
Just remember that fuel doesn't have a very long shelf life. I've heard people mention numbers between 3 and 6 months. Apparently there are additives that can be added to the fuel to keep it stable for longer.
Fuel stabilizers like Sta-Bil will keep ethanol-containing gas usable for a while longer
That only matters if you don't cycle your fuel around - you fill your fuel tank from the jerrycans, not the petrol station.
What happens with old fuel after 3-6 months? People with oil heaters often keep their diesel around for >1 year ...
Diesel has roughly ~double the shelf life as "normal" gas, so 6-12mo instead of 3-6. It doesn't just immediately go bad, but loses its energy slowly and burns less cleanly, so it could cause engine issues, but that's not super likely unless you've been storing it for a looong time.
I own a regular gasoline truck. It once spent over a year sitting in a driveway with no battery or driveshaft, and a half filled tank of gas.
After putting in a new battery and drive shaft, I didn't remember how much gas was in it anymore, so I took my 2gal can and put abiut half in to get it started.
No issues starting beyond the usual no gas primed in the line or fuel rail, so it took a second, and I drove it for about 50 miles before stopping at a gas station.
I have also never once swapped the gas in my mower after letting it sit all winter.
I understand that gas degrades, I just have never had gas that sat long enough to go bad I guess? I don't think 1 gallon of gas would "fix" 15 gallons of bad gas...
Lawn mower engines operate on nearly anything though.
Same with old vehicles, although newer gas with ethanol eats up the rubber.
i feel like gas last longer than that. since i had gas last over a year but i had put fuel cleaner in my car. there should be a PSA
Gas goes bad after a while. Especially if it's full of ethanol.
Does gas station gasoline usually have a lot of ethanol ...? And what does "goes bad" even mean for an oil-based product?
Depends on the state but usually yes. Gas station gas has all sorts of different things in it that turn to "varnish" if left to sit. Also the ethanol is hygroscopic meaning it absorbs water from the atmosphere.
