How Often Should I Run My Generator While Stored?

April 5, 2026

Quick Answer

Run your generator once every 3-4 weeks, for a duration of 30 minutes to 1 hour, to maintain its condition and prevent long-term damage.

Storage and Maintenance Requirements

When storing a generator for an extended period, it’s essential to follow the manufacturer’s guidelines for maintenance. Typically, this involves running the generator for 30 minutes to 1 hour every 3-4 weeks. This regular exercise helps to circulate the fuel, oil, and hydraulic fluids, preventing gelling and corrosion.

Fuel and Oil Considerations

If you’re storing your generator with fuel in the tank, it’s recommended to use a fuel stabilizer to prevent degradation. The stabilizer will help to prevent the fuel from breaking down and forming varnish, which can clog the engine and carburetor. Additionally, ensure the oil level is at the recommended level, but avoid overfilling, as this can lead to oil leaks and contamination.

Storage Best Practices

To minimize the risk of damage and corrosion, make sure to store your generator in a well-ventilated area, away from direct sunlight and moisture. Cover the generator with a breathable cloth or tarp to protect it from dust and debris. Also, disconnect the battery to prevent any accidental drain or spark. Follow these steps to maintain your generator in good condition and ensure it’s ready for use when needed.
