When it comes to backup power generation, having a reliable generator is essential. Whether you use it for emergency situations or as a primary source of power, ensuring your generator runs smoothly is crucial. One of the most common questions generator owners ask is, “How often should I exercise my generator?” In this guide, we’ll address this important question and provide you with all the information you need to keep your generator in optimal condition.

Why Exercise Your Generator?

Ensuring Reliability

Regularly exercising your generator is vital to ensure its reliability when you need it the most. Generators, like any mechanical equipment, require consistent use to stay in working order. When you don’t use your generator for extended periods, it can develop issues such as stale fuel, corroded components, or clogged filters. These problems can lead to breakdowns when you rely on your generator during a power outage.

Preventing Damage

Exercising your generator also helps prevent potential damage. When a generator sits idle for too long, moisture and condensation can build up inside, leading to rust and corrosion. Furthermore, engine parts may become stuck or seized, which can be costly to repair. Regularly running your generator keeps the engine and other components lubricated and in good condition.

How Often Should You Exercise Your Generator?

The ideal frequency for exercising your generator depends on several factors:


If you rely on your generator as a primary power source, it’s essential to exercise it more frequently. Generators used for backup power during emergencies can be exercised less often. For primary power sources, aim to run your generator for about 30 minutes every week. Backup generators, on the other hand, can be exercised once a month for 30 minutes.

Fuel Type

The type of fuel your generator uses can influence the exercise frequency. Diesel generators, for instance, are more tolerant of longer periods of inactivity compared to gasoline generators. Diesel fuel is less prone to deterioration, so you can exercise your diesel generator less frequently if needed.

Environmental Conditions

Environmental conditions also play a role in determining how often you should exercise your generator. In regions with extreme temperatures, it’s advisable to exercise your generator more frequently to combat moisture buildup and temperature-related issues.

Tips for Exercising Your Generator

To effectively exercise your generator and ensure its long-term reliability, follow these expert tips:

Regular Schedule

Create a regular schedule for exercising your generator, whether it’s weekly or monthly. Stick to this routine to maintain consistency and keep your generator in top shape.

Load Testing

During exercise, consider performing a load test to simulate real usage conditions. This helps ensure that your generator can handle the load when it’s needed most.


While exercising your generator, take the opportunity to inspect it for any visible signs of wear, damage, or leaks. Address any issues promptly to prevent further damage.

Fuel Maintenance

Pay attention to your generator’s fuel supply. Use fresh fuel and stabilizers if necessary to prevent fuel deterioration. Old or contaminated fuel can lead to engine problems.


So, how often should you exercise your generator? The answer to this depends on factors such as usage, fuel type, and environmental conditions. Regularly exercising your generator is crucial to maintain its reliability and prevent potential damage. By following a consistent schedule and implementing the tips provided, you can ensure that your generator is always ready to provide power when you need it most.
