How often should I change the oil in my standby generator?

Change the oil and filter during your generator’s regular maintenance, which we recommend at least once a year. If your unit runs often or powers critical loads, schedule service twice per year. Our service includes oil and filter changes along with testing and inspections to keep Generac and Honeywell systems reliable and within warranty guidance. We service Fort Wayne and nearby communities.

Quick owner checks:

• Run a 10–15 minute test monthly.
• Keep the area clear for ventilation.
• Check battery terminals for corrosion.
