What You Need to Know About Gasoline Storage

Gasoline doesn’t store very well over long periods of time, even with the addition of stabilizers and other fuel additives. It can be stored for 3-6 months, and diesel can be stored for 6-12 months. You can extend this time by adding a fuel stabilizer. If you choose to store gasoline as part of your fuel storage, know upfront that a real commitment to rotation needs to be made.

Portable generators can run on gasoline and can be used to power appliances and devices during power outages. If you need to fill your tank and can’t get to the gas station or the gas station is closed, having some extra gasoline stored for emergencies can come in handy.

PROS
  • Gasoline is widely available
CONS
  • Gasoline is highly flammable
  • Must be stored and used with caution - see storage requirements for more information
  • Note: Most cities prohibit this type of fuel from being stored in larger quantities above ground, so verify that it is legal to store gasoline in your area.
TIP

Rotate your stored gasoline every 6 to 12 months by adding the old to your car and buying new for your storage. Consider rotating your supply before seasonal blend changes—typically before winter—since gasoline formulations may vary.

Proper Storage Containers
  • Store in containers specifically designed for gasoline and diesel: typically, red for gasoline and yellow for diesel.
  • Ensure containers have an airtight seal to minimize spills when not in use and to prevent evaporation.
  • Include a pour spout that allows for controlled flow.
  • Preferably, containers should have automatic venting and safety locking mechanisms.
  • If plastic, make sure it is made of durable HDPE with barrier materials to minimize hydrocarbon permeation.
  • Metal fuel cans are also available; using an approved interior coating can help protect against corrosion and extend preservation.
  • Regularly inspect your fuel cans for leaks.
Storage Conditions
  • Store gasoline separately from other fuels and never inside your living space.
  • Keep it in a cool, dark, and well-ventilated area, such as a garage or outbuilding.
  • Ensure your stored gasoline or diesel is at least 50 feet away from any ignition sources.
  • Keep gasoline away from heat sources and moisture.
  • Always keep an ABC fire extinguisher near the storage area.
Shelf Life

3-6 months untreated, 6-12 months treated.

Frequently Asked Questions

Learn more about using gasoline as emergency fuel.

  • Gasoline can typically be stored for 3 to 6 months. With a fuel stabilizer, this can be extended, but rotation is still necessary. Diesel lasts longer—about 6 to 12 months under similar conditions.

  • Gasoline degrades over time, even with stabilizers. Regular rotation—such as adding old fuel to your car and replacing it with fresh fuel—helps ensure stored gasoline remains usable when needed.

  • Use containers specifically designed for gasoline—typically red cans made of durable HDPE plastic or metal. They should have airtight seals, controlled pour spouts, and safety venting features.

  • Gasoline should be stored in a cool, dark, and well-ventilated area, away from living spaces and at least 50 feet from any ignition source. Never store it inside your home.

  • Many cities restrict above-ground gasoline storage in larger quantities. Check local laws and regulations before storing gasoline at home to ensure compliance and safety.
