When Should I Change the Oil on My DuroMax Engine?

Proper oil maintenance is important to ensure long engine life and reliable performance for your DuroMax equipment, including generators, water pumps, and pressure washers.

Recommended Oil Change Schedule

Before Each Use

We recommend checking the engine oil level before every use to ensure the engine is properly lubricated.

Initial Break-In Oil Change

The first oil change should be completed after the first 8 hours of operation.

This break-in oil change helps remove small metal particles created during the initial engine break-in period.

Regular Maintenance Oil Changes

After the break-in period, follow these maintenance intervals:

• Every 100 hours of use for normal residential operation

• Every 50 hours of use for heavy-duty or commercial use

Frequent oil changes help maintain proper engine lubrication and performance.

Important Note

⚠ Always refer to your owner’s manual for the exact maintenance schedule for your specific model, as maintenance intervals may vary depending on the equipment and operating conditions.

Common Questions

Why is the first oil change done at 8 hours?

During the engine break-in period, small metal particles can accumulate in the oil. Changing the oil early helps remove these particles and protects internal engine components.

What happens if I do not change the oil regularly?

Old or contaminated oil can lead to:

• Increased engine wear

• Reduced engine performance

• Potential engine damage

Should I change the oil more often in hot or dusty conditions?

Yes. If the equipment is used in extreme temperatures, dusty environments, or heavy workloads, more frequent oil changes may be beneficial.
