gas consumption at idle?

Recently while elk hunting, I needed to have my truck run at idle for about an hour and a half.

My truck is a 2001 Ford F250 SD gas V8.

It was about 35 degrees, and I was at elevation of about 7500 feet.

Anyone able to tell me approximately how much gasoline the truck consumed while idling for 1.5 hours?

Thank you..... Lee Carkenord

gas consumption at idle?

I once heard that a 460 drank about a gallon every forty minutes or so at idle, but I have no clue where this number came from. My only guess is that it comes from: truck gets 10 mpg, truck goes 7 mph at 800 rpm, therefore, 7 / 10 = .7 Then: .7 * 60 min = 42 min.
But I really don't know. The only way to be sure would be to top off the tank, let it idle a couple of hours for a fairly acurate reading, and then see what it takes to fill 'er back up again.
