Does your Generac Generator need an oil change? Regular maintenances and oil changes help to keep your generator running properly.
It is recommended to change your generator's oil after the first month or 20 hours of use. After the initial oil change, every 6 months or 100 hours of use is the recommended.
Before starting refer to your owner's manual for your models specific oil brand, oil amount, maintenance schedule, and any tools needed for your generator.
*Before servicing your generator, make sure the generator is turned off, all receptacles are unplugged, and the spark plug is disconnected, to reduce the risk of accidental start-up.
Warming the oil by turning on the engine for a few minutes allows it to drain easier. Once the oil is warm, shut off your engine and allow it to cool before servicing your generator.
Place the oil drain pan under your generator to catch the oil when drained.
Loosen the drain plug with your socket wrench and drain the oil from the engine making sure to catch it with your oil drain pan.
Place the funnel in the oil fill tube and refill with the proper brand of oil recommended in your owner's manual. Fill until the oil reaches the threads in the oil fill tube.
Screw the oil dipstick back into the oil fill tube and wipe up any excess oil.
Start your engine for a few minutes and check for any oil leaks.
Regular oil changes can keep your generator running smoothly for the next power outage. Check your oil before and after every use to make sure you have the proper amount to run your generator by removing the dipstick. Fill with oil if needed.
Oil changes that are done on a regularly scheduled basis can prolong the life of your engine and keep it running properly so you won't be left in the dark during a power outage.
