There must be something in the Users Manual about such use. Our Generac standby generator at home states that the oil should be changed after 14 hours of continuous use!

That's got to be a misprint. If not, I don't think I'd select a Generac for my home standby generator. Changing the oil nearly twice every day would get old real fast.

Sometimes the manufacturer will schedule the initial oil change after a few hours because of using a "break in" oil type. However, subsequent changes should be less frequent than every 14 hours.
