Generator run time…
Just how long can you run a generator?
From the Jayco Owners Forum
Hey Mike,
I have a 2019 Greyhawk 29MVP that has an Onan 4000 generator. It's my understanding that you can continually run the generator for days as long as you make sure that the oil level is maintained. Is that true? What's the longest that you've continuously run an Onan 4000 generator?
Hopefully, this generator can keep up with the need to keep the RV cool in hot and humid weather. -Jaytalk
Dear Jaytalk,
Installed generators, such as your Onan 4000, as well as most portable generators from manufacturers including Energizer, Honda, Predator and others are designed to run continuously for days. But there’s a catch…
Maintenance is important!
Note that all generators require regular maintenance to keep them running. In the Onan manual they recommend air filter and oil changes every 150 hours (more often in hot or dusty conditions). So that’s at least once a week for 24/7 operation.
See the Onan maintenance schedule below
What about portable generators?
The same maintenance schedule applies for portable generators, but perhaps a little more often. Here’s what Honda recommends for their EU2200is generator. As you can see, Honda suggests an oil change every 100 hours and air filter cleaning every 50 hours. And this needs to be done more often under dusty conditions.
See the Honda EU2200is maintenance schedule below
Take care of your generator, and it will take care of you!
With proper maintenance any name-brand portable or installed generator should give you years of service. But failure to follow manufacturer maintenance recommendations could result in the loss of warranty coverage and cause an expensive repair. Make sure you stock enough oil and filters for your next camping trip.
I’ll be pulling maintenance on my Energizer 4500 generator in a few weeks, and will be sure to video the step by step procedure. It’s really not that difficult if you have a few basic tools and take your time. See you then…
Let’s play safe out there… Mike
Every generator is equipped with an indicator for when maintenance is due - it will stop making noise.
To remedy from this state, simply replace the part shown on the box.
It is hard to keep track of hour usage for maintenance on generators. Reason why when I purchased the Honda EU2200, I had the dealer install an hour meter on the generator, inexpensive but very usefull for me.
