Considerations and Maintenance Tips for RV Generators

Owning an RV means enjoying the freedom of life on the road, combined with many of the self-contained comforts of home. Whether it’s petrol generators or solar generators, these powerful engines make it possible to enjoy a warm shower, a freshly cooked meal, or a hot cup of coffee while travelling. 

All RV generators need regular care and maintenance to work at their best. At Diesel Generation Australia, we’ve put together the following maintenance considerations that RV owners should keep in mind. 

Run the Generator Frequently

Just like you, all engines and generators need exercise to run smoothly. For example, if your RV stays inactive or in storage during winter, you should still run the generator for at least one hour every 3 or 4 weeks to keep fuel from gumming up the generator. Turn on any large appliance to get the RV generator running at 50% load capacity or more.

Check the Hour Meter

It’s a good idea to physically inspect your RV generator after every 8 to 10 hours of run time. All RV generators should have an hour meter, which helps you keep track of how long the generator has been running. This is important, as it affects how frequently the oil should be changed. Check slip rings and brushes every 500 hours. Fuel filters should be changed approximately every 400 to 500 hours.

Drain Diesel Generators

RVs with diesel generators need the water drained from the fuel system once a year or after every 100 hours of run time. The coolant, radiator caps, and thermostat should also be replaced every 2 years. Inspect the rubber fuel supply lines annually for cracks or other damage. Check your owner’s manual for specific suggested maintenance to keep on top of what your generator model needs.


Like any vehicle engine, petrol generators need regular servicing in accordance with the manufacturer’s suggested intervals. This includes changing the oil, coolant, filter, and air cleaner. Many manufacturers recommend changing the oil after the first 50 hours and then every 150 hours after that. Once again, you should consult the owner’s manual for specific details.
