Oil Or No Oil? The Ultimate Guide To Generac Generator Oil Requirements

When purchasing a Generac generator, one of the most important questions to ask is whether or not it comes with oil. Generators require oil to lubricate their moving parts and ensure optimal performance and longevity. This blog post will delve into the answer to the question “does generac generator come with oil” and provide a comprehensive guide to generator oil requirements and maintenance.

Does Generac Generator Come with Oil?

The answer is: Yes

Generac generators typically come with oil pre-filled from the factory. However, it is essential to check the oil level before starting the generator to ensure it is at the appropriate level. If the oil level is low, add the recommended type and amount of oil as specified in the generator’s user manual.

Importance of Generator Oil

Generator oil plays a crucial role in maintaining the generator’s performance and lifespan:

• Lubrication: Oil reduces friction between moving parts, preventing wear and tear.
• Cooling: The oil helps dissipate heat generated by the engine, preventing overheating.
• Cleaning: Oil carries away contaminants and debris, keeping the engine clean.
• Sealing: Oil seals gaps between components, preventing leaks and ensuring efficient operation.

Recommended Oil Type and Amount

The type and amount of oil required for a Generac generator vary depending on the model. It is highly recommended to consult the generator’s user manual for specific oil requirements. Generally, Generac generators use either conventional or synthetic oil in the following viscosities:

• Conventional Oil: SAE 10W-30 or 10W-40
• Synthetic Oil: SAE 5W-30 or 5W-40

Checking and Changing Generator Oil

Regularly checking and changing the generator oil is essential for maintaining its performance:

Checking Oil Level:

1. Allow the generator to cool down.
2. Locate the oil dipstick.
3. Pull out the dipstick and wipe it clean.
4. Reinsert the dipstick and pull it out again.
5. Check the oil level on the dipstick. It should be between the “full” and “low” marks.

Changing Oil:

1. Gather the necessary supplies: new oil, oil filter (if applicable), oil pan, and funnel.
2. Allow the generator to cool down.
3. Place the oil pan under the generator’s oil drain plug.
4. Remove the oil drain plug and allow the oil to drain completely.
5. Replace the oil drain plug and tighten it securely.
6. Locate the oil filter (if applicable) and remove it.
7. Apply a thin layer of new oil to the gasket of the new oil filter.
8. Install the new oil filter and tighten it by hand.
9. Add the recommended amount of new oil to the generator using a funnel.
10. Check the oil level and adjust as necessary.

Oil Change Intervals

The frequency of oil changes depends on the type of oil used and the operating conditions of the generator. Generally, the following intervals are recommended:

• Conventional Oil: Every 50-100 hours of operation or annually
• Synthetic Oil: Every 200-500 hours of operation or every 2 years

Other Oil Maintenance Tips

• Use high-quality oil that meets the manufacturer’s specifications.
• Avoid using recycled or used oil.
• Store oil in a cool, dry place.
• Dispose of used oil properly at a designated recycling center.
• Keep a record of oil changes for future reference.

Troubleshooting Generator Oil Problems

If you encounter any problems with your generator’s oil, such as low oil levels or leaks, it is important to address them promptly to prevent damage:

• Low Oil Level: Check for leaks and add oil as necessary.
• Oil Leaks: Inspect the generator for any visible leaks and tighten loose connections or replace damaged seals.
• Dirty Oil: Change the oil and replace the oil filter as soon as possible.
• Overfilled Oil: Drain the excess oil to the appropriate level.

Summary: Ensuring Optimal Generator Performance

Generator oil plays a vital role in ensuring the longevity and performance of your Generac generator. By understanding the answer to “does generac generator come with oil” and following the recommended oil maintenance practices, you can keep your generator running smoothly for years to come.
