Where to buy

Hardware stores, auto parts shops and big box stores stock gas cans. Outdoor power equipment dealers carry them too.

A flame mitigation screen should sit inside the neck.

Keep the cap and vent closed tight.
Lock fuel cans away from kids and pets.
Add fuel stabilizer if gas will sit over a month.
Never store a gas can inside your home.

Rust or dents on a steel can.
Spout that leaks or will not lock.
Strong fuel smell when the can is closed.

Common questions

Why do new gas can spouts pour slowly?: Federal and California rules require spill proof spouts. Tilt and press firmly for flow.
Can I use a gas can for diesel?: Use a yellow can for diesel so the fuels never get mixed.
Can I put a gas can in my car?: Only for short trips, secured upright, with windows open. Remove it quickly.
How long does gas last in a can?: Plain gas starts to go stale within a few months. A stabilizer helps.
