Well today I did a little test of the onan, I hooked it up to an outboard fuel tank which I then filled with exactly 3 gallons of fuel. I then fired the beast up and went inside, turned on a 42 inch TV and Playstation, water heater, and ran the onan for 5 hours while I played Assassins Creed brotherhood. I would guess this is approximately 1/4 to 1/3rd load. When I shut off the onan I was surprised to find a decent amount of fuel still left in the outboard tank, so using a large pyrex measuring cup, I measured the remaining fuel, there was 1 gallon and 16 ounces left! So that means the onan ran for 5 hours on 1 7/8 gallons of fuel! Not bad for a 37 year old powerplant...

Hey;

GREAT information. Probably others will have different results, but
this gives me a good idea of how much fuel I might expect to use while
keeping the batteries charged out in the desert next week. Thanks
again.
