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

Change the oil per your generator manufacturer’s schedule; Parrish replaces oil and filter during our annual maintenance visit. Our certified technicians perform manufacturer-recommended checks, including battery voltage testing, verifying gas pressure, simulating a power outage to test the automatic transfer switch, and checking for gas leaks. Off-site Wi-Fi monitoring reviews weekly self-test reports and alerts us to service needs before storms in Fairfax or Alexandria. Ask about Priority Service Plans for turnkey upkeep.
