Fuel Recommendations

Polaris recommends the use of 87 octane or higher fuel in your generator.

Do not use fuel containing more than 10 percent ethanol. If the content of ethanol exceeds the specified limits, it may cause starting or performance problems. It also may damage the metal, rubber and plastic parts of the fuel system. Do not use gasoline containing methanol. Damage due to ethanol or methanol is not covered under warranty.

Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.

See the below diagrams for the location of the fuel tank cap (1).

When adding fuel:

1. Remove the fuel tank cap.

2. Fill carefully to avoid spilling fuel on the fuel tank strainer. Do not overfill the fuel tank. There should be no fuel above the upper limit mark. Do not fill above the bottom of the strainer. Fuel overflow may spill onto a hot engine and result in a fire or explosion. Damage caused by spilled fuel is not covered under warranty. Spilled fuel is a fire hazard, causes environmental damage and can damage paint and plastic. Wipe up spills immediately.

3. Tighten the fuel tank cap securely.

4. Position the fuel switch to OFF for storage or ON to operate the generator.

5. Move the generator away from the fueling source and fueling site before starting the engine.

Remember that gasoline is highly flammable and gasoline vapor is explosive under certain conditions. Take the following precautions when handling gasoline:

  • If the generator has been in operation, allow the engine to cool completely before refueling.
  • Always store gasoline in an approved container.
  • Always refuel outdoors or in a well-ventilated area away form any combustible materials. 
  • Do not smoke or allow open flames or sparks in or near the area where refueling is performed or gasoline is stored. Never refuel the engine inside a building where vapors may reach flames or sparks. Keep fuel vapors away from electrical appliances.
  • Never permit children to handle gasoline.
  • Never refuel around bystanders, pets and flammable objects.
  • Loosen the fuel cap slowly to relieve pressure in the tank.
  • Take care not to overfill or spill any fuel on the generator or muffler when refueling.
  • If gasoline spills on skin or clothing, immediately wash it off with soap and water and change clothing.
  • Do not use the generator if you observe leaking gasoline. Have the generator serviced immediately and before using it again.
