Why Change Your Generator Oil?

Engine oil serves as the lifeblood of your generator, lubricating moving parts and protecting them from wear and tear. Over time, oil breaks down and becomes contaminated with debris, losing its lubricating properties. This can lead to:

  • Increased Engine Wear: Dirty oil can’t effectively lubricate engine components, causing friction and premature wear.
  • Reduced Engine Performance: Oil sludge can clog oil passages, restricting oil flow and affecting engine performance.
  • Engine Damage: Extreme cases of oil contamination can lead to serious engine damage, requiring costly repairs.

To prevent these issues, it’s crucial to change your generator oil regularly. Generac recommends changing the oil every 50 hours of operation or annually, whichever comes first.

Gather Your Supplies: A Checklist for Success

Before you dive into changing the oil, ensure you have all the necessary supplies. Here’s a checklist:

  • New Engine Oil: Refer to your Generac generator’s owner’s manual for the recommended oil type and viscosity.
  • Oil Filter: Use a new oil filter specifically designed for your Generac model.
  • Oil Drain Pan: A large enough container to catch the old oil.
  • Wrench or Socket: To loosen the oil drain plug.
  • Oil Filter Wrench: To remove the old oil filter.
  • Clean Rags: For wiping up spills and cleaning surfaces.
  • Gloves: To protect your hands from oil and dirt.
  • Safety Glasses: To protect your eyes from potential splashes.

Safety First: Precautions to Take

Changing your generator oil is generally straightforward, but safety should always be a priority. Follow these precautions:

  • Work in a Well-Ventilated Area: Generator oil fumes can be harmful.
  • Wear Protective Gear: Always wear gloves and safety glasses to prevent oil contact.
  • Avoid Contact with Skin and Eyes: If oil gets on your skin, wash it immediately with soap and water.
  • Proper Disposal of Old Oil: Dispose of used oil responsibly at a designated recycling center.

Step-by-Step Guide: Changing Your Generac Generator Oil

Now that you have your supplies and are prepared, let’s walk through the process of changing your generator oil:
1. Warm Up the Engine: Start your generator and let it run for a few minutes to warm up the oil. This will make it easier to drain.
2. Locate the Oil Drain Plug: Refer to your owner’s manual for the location of the oil drain plug. It’s typically located on the bottom of the engine block.
3. Position the Oil Drain Pan: Place the oil drain pan directly beneath the drain plug to catch the used oil.
4. Loosen the Oil Drain Plug: Use a wrench or socket to loosen the oil drain plug. Be careful not to drop the plug into the drain pan.
5. Drain the Old Oil: Allow the oil to drain completely into the drain pan.
6. Tighten the Oil Drain Plug: Once the oil has drained, re-tighten the drain plug securely.
7. Locate the Oil Filter: The oil filter is usually located near the top of the engine.
8. Loosen the Oil Filter: Use an oil filter wrench to loosen the oil filter. Be careful not to damage the filter housing.
9. Remove the Old Oil Filter: Once the oil filter is loose, remove it by hand. Dispose of the old filter properly.
10. Clean the Filter Housing: Wipe the filter housing clean with a clean rag.
11. Install the New Oil Filter: Thread the new oil filter onto the filter housing by hand until it’s snug. Do not overtighten.
12. Add New Oil: Pour the recommended amount of new oil into the engine’s oil fill hole. Refer to your owner’s manual for the correct oil capacity.
13. Check the Oil Level: After adding oil, check the oil level using the dipstick. Ensure the oil level is within the recommended range.
14. Start the Engine: Start the generator and let it run for a few minutes. Check for leaks around the drain plug and filter.
15. Check the Oil Level Again: After the engine has run for a few minutes, check the oil level again and add more oil if needed.
