How to Properly Care for Your Generator – Especially Before the Next Big Storm Hits

When a hurricane or powerful storm rolls in, the last thing you want is to discover your generator won’t start. A properly maintained generator can be the difference between comfort and chaos during an extended power outage. Whether you're keeping the lights on, your refrigerator running, or a sump pump working through a flood, your generator becomes your home's lifeline when the grid goes down.

But just like any other machine, a generator needs regular care to stay reliable. Neglecting maintenance can lead to costly repairs—or worse, a complete failure when you need it most. Here’s how you can keep your generator in top working order year-round, so it’s ready when the next storm or hurricane comes your way.

Think of your generator like a car engine—it needs clean oil to run efficiently. Check your owner’s manual for the recommended oil change interval (usually every 50 to 100 hours of use). Even if it’s not used often, oil can break down over time, so consider changing it at least once a year.

Pro tip: Always check the oil level before starting the generator, especially if it’s been sitting unused for a while.

A dirty air filter reduces efficiency and can damage the engine. Inspect it every few months, and more frequently during heavy use or in dusty environments. Clean or replace it according to the manufacturer's recommendations.

Gasoline degrades over time and can gum up your carburetor or fuel lines. Always use fresh gas and add a fuel stabilizer if the generator will be sitting unused for more than 30 days. For added peace of mind, consider running the generator monthly for 10-15 minutes to keep fuel flowing and parts lubricated.

Alternative option: Propane and diesel generators store fuel longer but still require occasional checks to ensure fuel quality.

A worn or fouled spark plug can make starting your generator difficult. Remove it periodically to check for buildup, cracks, or wear. Clean it with a wire brush or replace it as needed—this is a quick and inexpensive fix that can save you big headaches later.

If your generator has an electric start, keep the battery charged and inspect it for corrosion or leaks. A dead battery can render your generator useless unless you have a manual recoil backup.

Keep your generator in a dry, ventilated space, protected from dust and moisture. If possible, store it with a cover made specifically for your model. Never run it indoors or in a closed garage due to the risk of carbon monoxide poisoning.

Start your generator once a month and let it run under load for 10-15 minutes. This keeps fluids moving and identifies any potential issues before they become major problems.

Even if you’re diligent with upkeep, having a professional inspect your generator once a year is smart. They can catch early signs of wear or damage and ensure everything’s functioning correctly.

Power outages from storms and hurricanes are unpredictable—but your generator’s performance doesn’t have to be. With a little attention and regular maintenance, you’ll be prepared for whatever Mother Nature throws your way. Treat your generator with care, and it will take care of you when you need it most.

Don’t wait for the next outage to discover something’s wrong. Check it today—your future self will thank you.
