I have not measured it.

When I left my car idling off a half gallon jug that was about half full....I came back after 25 mins at it hadn't even used half of that yet....so that'd be less than 16 oz of fuel in a 20-25 min span. or roughly 40oz an hour is my guess, and with 128oz in a gallon, thats right around .29 to .32 gallons per hour...so I agree with your estimate...

It depends on what load is on the engine, eletrical goodies and A/C on would probably increase it quite a bit, and removing all belts except one for the waterpump/cooling fan would probably increase it slightly.

Our minivan probably uses just over 1.5 gallons PER HOUR.

We idled it for about an hour before for electrical power (inverter) and the thing drank over a gallon. That means even with a full to the brim tank (21gallons) it'd barely run for a day! Our diesels could probably idle over 3! Pretty sad considering they're both 3.0 liter engines, and the gasser one is "far newer and supposedly more sophistocated" Sure it is...
