Gas powered generators are very similar to lawn mover engines

Think what would happen to your lawn mower if you ran it for 12 or 18 hours straight

You oil would be mud in no time at all

I have a Yamaha EF2400iS generator. Great machine. Super quiet. On page 20 of the owner's manual it says to replace the oil initially after 20 hours run time. Then every 100 hours run time.

The generator is three years old. I use it a lot. I change the oil every 50-75 hours run time. I use synthetic oil. No problems so far.
