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

Plan to change your standby generator’s oil during your annual service visit. Exact timing depends on your generator model, runtime hours, and local conditions, and a technician will confirm on site. First Call Jewel services Generac units in Idaho Falls and across rural areas, and customers routinely schedule yearly maintenance. If your unit runs long during an outage, you may need an extra oil and filter change before the next annual visit.

Quick checks:

• Review the runtime meter after extended outages.
• Watch for low-oil alerts.
• Keep fuel supply and clearances verified during service.
