How To Change The Oil On A Champion Dual Fuel Generator

Aside from the fuel, your Champion dual-fuel generator needs engine oil to run. You cannot use it without engine oil, whether it is powered by gasoline or propane gas.

Your generator should always have the right amount of oil in the tank.

See a Champion dual-fuel generator on Amazon.

That's why you must always check if there's oil in your generator before using it. These generators have an auto shutoff feature which means you cannot use your generator when the oil level falls below the threshold level.

The oil is essential because it ensures that your dual-fuel generator's components are correctly lubricated. This allows them to operate smoothly, without friction, which hastens wear and tear on any machine or equipment.

It'll also prevent overheating and help wash away dirt, dust, and other impurities that have settled in the interiors of your generator. The results are an appliance that performs at its optimum level and has an extended lifespan.

Changing the engine oil on your generator is an important part of its maintenance. Check your manual for the recommended schedule on how many operating hours should have passed before you need to have it changed again.

Champion Dual Fuel Generator Oil Change

Here's how to change the oil in your Champion dual-fuel generator.

Step 1. Positioning

Ensure you position your generator on a flat, level surface and a well-ventilated area outside your home. Observe proper clearance from the walls and other things that can interfere with proper airflow.

Step 2. Oil Type and Required Amount

Check your owner's manual for the recommended engine oil type and amount to use on your dual-fuel generator. The amount and type would vary depending on your unit's oil capacity and the prevailing ambient temperature.

Ordinarily, 10w-30 engine oil is used, but you should use a different oil when using the generator under extreme weather conditions.

If your unit is brand new, you need to change the oil after 5 hours of usage, or what is referred to as the break-in period.

This will help rid the generator of dirt, dust, and other contaminants it has acquired during manufacturing and shipping.

Step 3. Drain Old Oil

Remove the oil drain bolt. This is found at the bottom portion of the crankcase. Put a bucket or container directly underneath the oil drain bolt so it can catch the old oil.

Put back the oil drain bolt once the used oil tank has emptied. Dispose of the old oil properly.

Step 4. Oil Fill Cap

Locate and remove the oil fill cap in your unit. You can also use this as your dipstick to know if you already have the right amount of oil in the tank.

Step 5. Add Oil

Put a funnel on the opening to add the appropriate engine oil type and the right amount inside the tank. Do not overfill your oil tank. Check to see that at least one or two threads are visible on the fill hole.

Your Champion dual-fuel generator comes with an oil funnel upon purchase.

Step 6. Close The Oil Tank

Screw the oil fill cap securely in place to prevent leaks. Wipe off any excess oil or dirt on the surface.

Other Things To Remember

You should change the oil when the engine is warm so that it'll flow smoothly. Consult your manual to familiarize yourself with the parts of your generator to guide you in this task.

How Much Oil Does A Champion Dual-Fuel Generator Need?

Champion offers various dual-fuel generators with varying wattage and oil capacities.

For example, their 2000-watt and 2400-watt dual fuel generators have an oil capacity of 0.4 quarts, while the 3500-watt and 3800-watt units have a total of 0.6 quarts.

It's best to check your manual for the recommended engine oil for your generator's model to function efficiently and effectively.

Remember that it's not advisable to overfill your oil tank. You can use the oil fill cap to check the oil level, or a visual inspection of the oil tank's opening can also help.

There should be at least one or two visible threads (without oil) on the part where you screw the oil fill cap. This space allowance is essential so the oil won't overflow when using your engine.

This time, the engine oil that you use isn't dependent on the model of your Champion dual fuel generator.

It depends on the prevailing weather. Ambient temperature will dictate how well the engine oil will perform. Champion recommends four different automotive oils for its dual-fuel generators.

These include:

  • 10W-30. This is used under normal conditions. It performs well in temperatures ranging from 20 degrees Fahrenheit to more than 120 degrees Fahrenheit.
  • 5W-30. This is used during freezing weather to help your generator function smoothly despite the cold temperature. It works well from 0 degrees to -20 degrees Fahrenheit or even colder.
  • 10W-40. This one is recommended for warmer weather or when ambient temperatures range from 80 to more than 120 degrees Fahrenheit.
  • 5W-30 Synthetic. This works fine on both ends of the spectrum whether the weather is freezing (more than -20 degrees Fahrenheit) or super hot (120 degrees Fahrenheit or higher).

Find this 10W-30 automotive oil on Amazon.

As a guide, the letter W stands for winter.

The number before it is the engine oil's viscosity or thickness during low temperatures, while the number that follows after the letter is its viscosity during regular operation of the generator's engine.

Take note also that you cannot use synthetic oil until you're done with the break-in period or after 5 hours of use of your generator.

How Often Should You Change The Oil In A Champion Generator?

As mentioned earlier, changing the oil on your Champion dual-fuel generator is routine maintenance. This ensures that your appliance performs optimally each time you use it and that you're helping it last longer.

On average, Champion generators require changing the oil after 50 to 100 hours of operation. The schedule can vary depending on how often you use your appliance.

If you use it often, you have to change the oil after a shorter time compared to when you only use the generator occasionally.

This is why there's no set number of days or months before you perform this maintenance. It would depend on your usage so take note of the number of hours you use it.

Check your owner's manual for the recommended schedule. The manufacturers would know best when their products would need this routine maintenance.

What Happens If I Don't Change My Generator's Oil?

Knowing the importance of changing the oil and what could happen to your machine if you don't follow the recommended schedule is good.

So many things can go wrong if you don't change the oil after the set number of hours of usage. Here are some of them.


Dirt, dust, metal, and other unwanted particles will continue to accumulate inside the generator's engine. When this happens, they can clog pathways that'll prevent the smooth functioning of your unit.


The engine oil absorbs the heat generated by using the machine. Without it running throughout the engine pathways, the generator could heat up and cause other parts to malfunction.

The gasket can be blown off, or the machine can stop functioning altogether.

Service Interruption

Since the generator's operation isn't working smoothly, its performance and service will be affected. Users can experience power interruptions or no service due to the complete malfunctioning of the generator.

Shorter Lifespan

Lubrication ensures there's no friction among moving parts. Friction is the ally of wear and tear. If there's friction, your generator will show signs of deterioration earlier than expected.

Vital parts can be damaged. Either you spend more on repair costs, or you won't be able to use your generator anymore.

Simply put, your generator will undergo complete engine failure, and you won't get the most out of your investment.

To Finish Up
