Protect your generac generator: essential oil change guide for peak performance

Maintaining your Generac generator is crucial for its longevity and performance. One essential maintenance task is changing the oil regularly. This blog post will provide a comprehensive guide on how to change Generac generator oil, ensuring optimal operation and extending its lifespan.

Safety Precautions

Before beginning, ensure the following safety precautions:

• Turn off the generator and allow it to cool completely.
• Disconnect the spark plug wire to prevent accidental starting.
• Wear appropriate safety gear, including gloves and eye protection.

Tools and Materials Required

• Generac-approved oil filter
• Generac-approved oil (type and viscosity as per manufacturer’s recommendations)
• Oil pan
• Funnel
• Rags or paper towels
• Wrench or socket set

Step-by-Step Instructions

1. Locate the Oil Drain Plug

The oil drain plug is typically located at the bottom of the engine oil pan. It is usually a 17mm or 19mm bolt. Place the oil pan beneath the drain plug.

2. Drain the Old Oil

Using a wrench or socket, carefully loosen the oil drain plug. Allow the oil to drain completely into the oil pan. Note: The oil may be hot, so proceed with caution.

3. Replace the Oil Filter

Locate the oil filter, which is typically a cylindrical component near the top of the engine. Use an oil filter wrench to loosen and remove the old filter. Apply a thin layer of new oil to the gasket of the new filter and screw it on hand-tight. Tighten it further using the oil filter wrench, but avoid overtightening.

4. Add New Oil

Insert the funnel into the oil fill port, usually located on the top of the engine. Pour the Generac-approved oil into the funnel, checking the oil level regularly using the dipstick. Add oil until it reaches the “Full” mark on the dipstick.

5. Check for Leaks

Start the generator and let it run for a few minutes. Check for any oil leaks around the oil drain plug and oil filter. If any leaks are present, tighten the components as necessary.

6. Reset the Oil Change Indicator

Some Generac generators have an oil change indicator light. If your generator has this feature, follow the manufacturer’s instructions to reset the indicator after changing the oil.

7. Dispose of Old Oil and Filter Properly

Dispose of the old oil and oil filter in accordance with local environmental regulations. Never pour oil down the drain or into the ground.

Oil Change Frequency

The frequency of oil changes will vary depending on the type of generator and operating conditions. Generac recommends changing the oil every 100 hours of operation or annually, whichever comes first. However, if the generator is used frequently or under heavy loads, more frequent oil changes may be necessary.

Key Points: Ensuring Generator Longevity

By following these steps, you can ensure that your Generac generator receives the proper maintenance it needs to perform optimally and last for years to come. Regular oil changes are a critical part of this maintenance routine, helping to keep your generator running smoothly and reliably when you need it most.
