Generator Maintenance
How often should I have my generator serviced? How many hours of running it, without service or new oil, etc... Any help is greatly appreciated.

I have an Onan 7.5KW diesel generator and change the oil & oil filter every 150 hours or one year which ever comes first and the fuel filter every two years.I change the air filter whenever it looks like it needs changing. I had a 1983 Onan 7.5kw diesel generator on a commercial fishing boat which during the 4+ months of the fishing season the generator ran 24/7. We changed the oil and oil filter every 400 hours and the fuel filter every 750 hours. We rarely changed the air filter because the environment had no road dust etc. When I sold the boat the Onan had over 6,000 hours. It was still going strong. If you run your diesel generator constantly/frequently they will run for a long time. Great product. Most diesel generators will last for a very long time if they are run and routinely serviced.
