Depends on the generator. I'm very conservative and I use nothing but 5w40 HDEO oil in all of my engines.

For example:

Aircooled high rpm (3600 rpm) generator with no oil filter, I'd change interval at 50 hours.

Aircooled inverter generator with no oil filter, I'd change interval at 100 hours or 2 weeks use whichever is longer. I had no problem running 2 weeks between oil changes running my generator 6-8 hours a day.

Water cooled and/or generators with oil filters, I'm comfortable with 150 to 200 hour intervals with a high quality synthetic HDEO.

In Afghanistan, our diesel generators ran 24 hours a day and were shut down one a week for about 30 minutes for the oil and filter to be change which amounted to about an oil change every 167 hours or so.
