Common problem

How Often Should I Bleed Old Gas Out of the Generator?

If the generator has been idle for more than 30 days, it is best to drain the old gas from the generator. Gasoline will begin to degrade after this time, which can cause starting problems and damage your generator’s carburetor.

Can I dispose of old gas by pouring it down the drain?

No, it’s not safe to pour old gasoline down the drain. Gasoline is a hazardous substance that harms the environment and pollutes groundwater. Instead, take the old gas to a hazardous waste collection point or contact your local waste management agency for disposal instructions.

Do I need to add fuel stabilizer when storing gas?

Adding fuel stabilizers helps extend the shelf life of gasoline and prevents it from going bad. If you plan to store the gas for more than a few weeks, it is a good idea to add a fuel stabilizer to the gas container.

Can I use old gasoline from a generator in my car or lawn mower?

It is not recommended to use old gasoline from generators on other gasoline powered machines. Over time, gasoline deteriorates and loses its potency, which can cause problems with starting and running. It is best to safely dispose of the old gas and use fresh gas in your other machines.

What should I do if my generator won’t start after venting old gas?

If your generator won’t start after you’ve bled out old gas, there may be other issues that need to be addressed. Check the spark plugs, air filter and carburetor to make sure they are clean and functioning properly. If you continue to have problems, consult your owner’s manual or consult a qualified technician for assistance.
