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

Change the oil per your generator manufacturer’s schedule, which is based on run hours and time in service. We include oil changes, filter replacements, and inspections in routine generator maintenance. If your generator ran for many hours during a storm or outage, schedule service soon. Our licensed team services whole-home generators in Roanoke and Martinsville and can advise the right interval for your model. Diamond Club members receive priority service and one annual electrical inspection.
