After a hurricane a few years ago, I idled my engine for about 8 hours while hooked up to a 2KW inverter that was used to power fans and wet-vacs to help clean out the water from a marina store.
After refilling the truck and dividing by 8 hours I figured it burned under .5 gallons per hour.

I used to be able to run my Perkins diesel powered 42 foot Ketch at about 1/2 gallon an hour if I took it easy in smooth water. My buddy put many miles on his boat at 1/3 gallon an hour. It seems like while idleing a Cummins with no load, 1/4 to 1/3 gallon an hour would be about right. In your case you had a demand of about 2-3 hp. So .5 makes a lot of sense. I can't see how the number could be at 1 gallon, as previously said, unless it was a gasser.

Look at what that UPS driver is saying. It wouldn't burn and cook if it was left there for an hour or more after shutoff. I disagree on the "expenisve oils" comment cause a good bypass filter and oil analysis with extended drain intervals will work out a lot cheaper than dinos every time. Now these guys running bypass' with syns and going crazy with the 3,000 mile oil changes yeah thats a waste.

annabelle, sort of (for the most part) - I used a high idle "wooden stick" between the throttle pedal and seat to try and keep the revs above 1000. I don't have the cruise control high idle set up if thats what you're referring to.
I know I said under .5, but I found my notes later and it was really ~.3 gal/hour.
FWIW, I used to work at UPS in the late 70's putting myself through college and I remember the day when management said to shut off the engines for each stop - a few guys rolled there eyes and said that for whatever money they were saving on gas - they'd end up spending it on new starters. But that never happened as I recall. We used the Ford I-6 back then in the 6 and 8 cubes.
