4.3.1— Engine Oil Recommendations
To maintain the warranty, genuine Generac replacement parts MUST be used, including Generac oil kits (which include an oil and air filter). Gen-
erac oil kits can be obtained through an Authorized Dealer or purchased on-line. To purchase on-line, access the maintenance kits page through
www.generac.com or directly at shop.generac.com. Follow the prompts to enter delivery information and complete the purchase.
All Generac oil kits meet minimum American Petroleum Institute (API) Service Class SJ, SL, or better. Use no special additives. Select the appro-
priate viscosity oil grade according to the expected operating temperature. Synthetic oil also can be used in the appropriate weight as standard.
Figure 4-1: Recommended Oil Based on Temperature
• SAE 30 above 32 ºF (0 ºC)
• 10W-30 between 40 and -10 ºF (4 and -23 ºC)
• Synthetic 5W-30 for all temperature ranges
Any attempt to crank or start the engine before it has been properly serviced with the recommended oil may result
in an engine failure.
4.3.2— Changing the Oil and Oil Filter
1. Start the engine by pressing the MANUAL button on the control panel and allow the engine to run for 5 minutes. Then, press the Control
Panel OFF button to shut down the engine.
2. A few minutes after the engine shuts OFF, when it has cooled slightly, lift the lid and remove the front panel. Pull the oil drain hose free of its
retaining clip. Remove the cap from the hose and drain the oil into a suitable container.
3. After the oil has drained, replace the cap onto the end of the oil drain hose. Reposition and secure the hose with the retaining clip.
4. With the oil drained, remove the old oil filter by turning it counterclockwise. For filter location, see Figure 4-2.
5. Apply a light coating of clean engine oil to the gasket of the new filter.
6. Screw the new filter on by hand until its gasket lightly contacts the oil filter adapter. Then, tighten the filter an additional 3/4 to one full turn.
7. Refill the engine with the proper recommended oil. For recommended oil, see Figure 4-1.
8. Start the engine, run for 1 minute, and check for leaks.
9. Shutdown the engine and recheck the oil level. Add oil as needed. DO NOT OVER FILL.
10. Re-insert dipstick and/or reattach fill cap.
11. Press the Control Panel AUTO button.
12. Dispose of the used oil and filter at a proper collection center.
