Adding Engine Oil
Before starting the generator, ensure the engine oil is at the correct level. Remove the oil dipstick, wipe it clean, reinsert without threading, and then remove to check the oil level. Add the recommended type and amount of engine oil (typically 10W-30) using a funnel until the oil level is between the 'Full' and 'Add' marks on the dipstick. Do not overfill.
Adding Gasoline
Ensure the generator is on a level surface and the engine is off and cool. Remove the fuel cap and slowly add fresh, unleaded gasoline to the fuel tank. Do not overfill; leave space for fuel expansion. Replace the fuel cap securely. Refer to the fuel filter red line to avoid overfilling.

Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your Generac GP15000E generator. Always refer to the detailed maintenance schedule in your full user manual.
Engine Oil Change
Change the engine oil after the first 20 hours of operation, and then every 50-100 hours or annually thereafter, depending on usage. Ensure the engine is warm before draining the oil for better flow. Use the recommended oil type and capacity.
Spark Plug Inspection
Inspect the spark plug every 100 hours or annually. Clean or replace the spark plug if it is fouled, discolored, or has excessive wear. Ensure the gap is set correctly according to specifications in your manual.
Air Filter Cleaning
Clean the air filter element every 50 hours or more frequently in dusty conditions. Remove the air filter cover, take out the foam element, and wash it with warm, soapy water. Rinse thoroughly, squeeze dry, and lightly oil before reinstalling.
Troubleshooting
If your generator experiences issues, consult this basic guide before contacting support:
- Engine Fails to Start: Check fuel level, engine oil level, spark plug condition, and ensure the fuel valve is open and the engine switch is ON.
- No Power Output: Verify all circuit breakers are in the 'ON' position. Ensure no connected devices are overloading the generator.
- Engine Runs Rough: Check for stale fuel, dirty air filter, or a fouled spark plug.
- Low Oil Shutdown: If the generator shuts down unexpectedly, check the engine oil level and add oil if necessary.
