fuel usage for hi idle mod

[oafydude28]

Does any one know how much fuel the 6.0 uses at idle vs the high idle in gallons per hour?

If I remember I'll check for sure tomorrow morning, with the scan guage.
Low idle is like something like .7-.9 g/hr when cold
Factory elevated idle .9-1.2 g/hr cold
Elevated idle mod PTO 1200 RPM 1.2-1.4 g/hr cold

I've seen at operating temp. low idle .4g/hr I think???
Elevated idle mod PTO .4g/hr Know for sure there.

Thank you. i wanted to know because i would like to use the truck for heat on the cold days here in Minnesota while working. .4 gph seems pretty good.

Just rechecked the operating temp running and it varied from .4-.5 g/hr, both low idle and the elevated idle switch.
