Storing Fuel Safely, at a Glance

A generator is only as ready as the fuel sitting next to it. This guide walks through approved containers, safe storage locations, gasoline shelf life, and propane tank handling in plain English, so the one time you need it, it starts. There's a printable 29-page version up top.

Common Questions

1 What container should I use for gasoline?

Only an approved, purpose-built fuel container — a plastic or metal can rated for gasoline, with a tight, self-venting cap. Never a repurposed jug or a glass container.

2 How long does gasoline actually last in storage?

Untreated, plan on a matter of months before it starts to degrade. A stabilizer added at fill-up commonly extends that to roughly a year, though it's best used well within that window.

3 Where should fuel be stored?

Outdoors or in a detached, ventilated space — never in the house, an attached garage, or anywhere near a water heater, furnace, or other pilot light.

4 Does propane go bad in storage?

The propane itself stores for years without degrading. The tank is what eventually needs attention — it's stamped with a manufacture date and needs periodic professional recertification.

5 Why does everyone say to use ethanol-free gas?

Ethanol-blended gasoline, the kind sold at most pumps, tends to absorb moisture and break down faster than ethanol-free gas. For fuel you're setting aside, ethanol-free generally holds up longer.

6 What's the single biggest fuel-storage mistake?

Fuel that's simply forgotten — filled once and never rotated. Stale fuel gumming the carburetor is the most common reason a generator won't start, and it's entirely preventable.

Would you rather I just do this for you?

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.

Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
