Fuel Maintenance: Keeping Your Generator Ready When It Matters Most

A generator is only as good as the fuel running through it. Keeping the fuel system in good shape is one of the smartest ways to extend the life of your equipment and make sure it’s ready when you need it. From storage tips to regular checkups, here’s what you should know about fuel system care.

Simple, Reliable Fuel Maintenance Steps

Change Air Filters on a Schedule

Your generator relies on steady airflow to run properly. When the air filter gets clogged, it forces the system to work harder than necessary. This wears out parts faster and burns more fuel. Swapping out air filters regularly keeps everything running smoothly and saves fuel in the long run.

Add a Fuel Stabilizer

If your generator isn’t running often, the fuel inside the tank can start to break down. Over time, this creates a build-up that clogs injectors and causes other headaches. A good fuel stabilizer keeps fuel fresh, helps prevent sludge, and protects your fuel system between uses.

Clean Out the Fuel Tank

Sediment, moisture, and grime naturally settle at the bottom of your fuel tank over time. Regular cleanings prevent clogs and stop corrosion before it turns into expensive damage. A quick check every so often can help you catch issues early and keep your fuel system in good shape.

Inspect Fuel Lines for Damage

Fuel lines can crack, leak, or clog. You don’t want to find out about those problems during a power outage. Regularly checking your fuel lines for wear helps avoid breakdowns and keeps fuel flowing to the engine like it should.

Stay on Top of Oil Changes

Clean oil helps protect your engine and improves how your generator runs. When oil gets old, it forces the engine to work harder, burns extra fuel, and puts extra strain on your equipment. Changing the oil as recommended helps your generator run reliably and efficiently.

How to Store Fuel the Right Way

How you store your fuel matters just as much as how you maintain your generator. Use airtight, approved containers such as metal fuel cans or heavy-duty plastic ones made for fuel storage. Keep them in a cool, dry spot away from direct heat, sparks, or anything that could ignite them.

Never leave a fuel container open, and store it somewhere well-ventilated, like a detached garage or outdoor shed. Remember, even in the best conditions:

• Diesel fuel can last up to three years.


• Gasoline usually holds up for six months to a year.

Label your fuel with the date you stored it and rotate your supply to avoid using old, degraded fuel that could cause problems when you least expect it.
