Gasoline Storage and Fuel Treatment

If you own a lawn mower or other engine-powered equipment, you must store the gasoline used to fuel it. Gasoline is flammable and must be stored properly to avoid fires. In addition, if you store gasoline for more than three months, it degrades and becomes less effective.

Storing Gasoline

Store gasoline in containers approved by the Underwriters Laboratories (UL) or Factory Mutual (FM). Fill containers 90 percent to 95 percent full to allow for expansion. Keep gasoline in a cool, dark, dry area separate from the house, such as a shed. If you need to store large quantities of gasoline, use a flammables cabinet.

Safety Precautions

Never smoke around stored gasoline. Keep gasoline away from children and pets. Keep gasoline containers tightly closed when not in use. Refuel equipment outdoors, when possible, and always wait for small engines to cool off before adding gasoline.

Fuel Stabilizers

Fuel stabilizers refer to products you can add to gasoline to prevent degradation. Without a stabilizer, gasoline becomes less effective within three months. Add stabilizers while gasoline is fresh; stabilizers cannot reverse degradation. Stabilizers are available at automotive and engine stores.
