How Much Fuel to Keep, at a Glance
The most common fuel mistake isn't storing too little — it's storing a lot and forgetting it until it's stale. This guide covers a sensible amount to keep and a simple rotation habit in plain English, so your fuel works when you need it. There's a printable 29-page version up top.
Common Questions
1 How much fuel should I keep on hand?
Enough for the outage you realistically expect, plus a modest cushion. Little and fresh beats a lot and forgotten — a big stockpile is a fire load and mostly stale fuel besides.
2 How do I keep stored gasoline fresh?
Date every can, use the oldest first (run it through the car or mower), and refill with fresh fuel and stabilizer. A reminder every few months makes it almost automatic.
3 How long does gasoline last in storage?
Untreated, plan on a matter of months before quality drops. Stabilizer extends that, but it's best used well within the product's stated window. When in doubt, rotate it out.
4 Do I have to rotate propane too?
No — propane stores for years without going bad. You just keep enough full cylinders and make sure the tanks are sound and not due for recertification.
5 How much am I allowed to store at home?
That's set by your local fire code, which varies by area. Call your local fire department for the limit at your address before storing more than a couple of containers.
6 What do I do with fuel that's too old?
Take it to a household hazardous waste site or collection day — never the trash, a drain, or the ground. Your local waste authority can point you to the nearest drop-off.
Would You Rather I Just Help?
