I have a 4000W generator. Does anyone know how often Do I need to change its oil? Thanks for your advice.

Thank you very much for all your comments and advices. I purchased my RV one year ago and now it has 12,000 miles. I think it's worth it if I want to keep it a little longer.
Per Onan Handbook every 150 hours or once per year whichever occurs first.
Breakin oil change at 50 hours.
I have the Onan 5500 generator. The manufacturer recommendation was 50 hours. I checked it a 50, and the oil was like new with no particles. Just saying, YMMV.

In the 15 years I owned my last coach, I never changed the oil in the generator. Like others have mentioned, the chances of a small engine failing from lack of oil changes is near nil. I kept the air filter clean, ensured there was sufficient oil in the engine and occasionally cleaned the carb. The generator ran like a top every time I started it. In a small engine run at a constant rpm sufficient oil is more important than clean oil.
