This Is the Fuel Used by Honda’s Generators (Fuel Tips)

Using outdated gas or the incorrect type of gas is a common cause of generator failure. Gas not only affects fuel economy, but the improper gas can cause serious engine damage.

Honda generators require unleaded fuel with an octane value of 87 or higher and no more than 10% ethanol.

Refueling your generator should only ever be done while the engine is turned off and in a well-ventilated environment. Please observe the Honda’s recommended safety measures.

Selecting the Appropriate Gasoline for a Honda Generator

A generator’s efficiency is greatly impacted by the gas it is fed.

Always use new gasoline with a low ethanol concentration to reduce the likelihood of fuel-related issues. Additionally, I think it would be wise to use a fuel additive to assist eliminate moisture and stabilize gas.

Contains Minimal Amounts of Ethanol

Ethanol is added to gasoline to reduce emissions, but it is not a suitable fuel for the Honda generator’s small engine.

Water is drawn to ethanol by its very nature. Fuel limits may result from the varnish left behind by the mixture of water and ethanol.

This includes the carburetor, which can fail as a result of a lack of fuel.

Never use gas with more than 10% ethanol in it due to the damage it can do to the fuel system. The ethanol content should be as low as possible.

Fuels labeled “E15,” “E30,” or “E85” should be avoided. These fuels have anything from 15 to 30 to 85 percent ethanol, respectively.

Fill Up With New Gasoline

After only 30 days in storage, gasoline can start to degrade. For this reason, you should buy gas as close to this time as possible and utilize it up.

If you only use your generator during blackouts, estimating how quickly you will burn through a tank of gas can be challenging. Because of this, I always have my larger portable generator on hand.

Every time I fill up the tank, I put in some fuel stabilizer to make the gas last a bit longer before it degrades.

Fuel stabilization is a must

Improve the longevity of gasoline by adding a fuel stabilizer while it is still in good condition. The consequences of stale gas cannot be undone by fuel additives.

Every time I fill up, I prefer to use Sea Foam Motor Treatment. Sea Foam serves multiple purposes, including gas stabilization, fuel system cleaning, and moisture reduction. It reduces the likelihood of issues caused by using stale fuel.

STA-BIL is an additional useful fuel additive option.

Fuel That Doesn’t Use Ethanol (Optional)

The harmful effects of ethanol on the generator can be avoided by switching to a gas that contains no ethanol. Ethanol-free gas is the most cost-effective fuel for your Honda, but it’s also the most expensive.

Some gas stations offer gasoline that does not include ethanol. This product is marketed as REC-90, or recreational fuel. Finding a gas station in your area is easy when you use

Canisters of 4-cycle fuel by TruFuel are available at most home improvement stores and on the web. Canisters are a practical choice to keep on hand.

A Few Words on Getting and Keeping Gas for Your Honda Generator

Using outdated gas or the incorrect type of gas in a Honda generator can prevent it from starting. These are some short guidelines to keep in mind when selecting and storing gas:

  • Fresh gas should be used, and it should be used up, within 30 days.
  • Fuel having an octane value of 87 or above and no more than 10% ethanol can be used in unleaded vehicles.
  • When gas will sit unused for more than 30 days, add a fuel stabilizer.
  • Gasoline should be kept in a cold, dry place, apart from anything that could catch fire.
