According to my VAGCOM, my TDi burns .5 liters per hour @ idle when cold. Never checked it hot. That's for a 1.9 liter, 4 cylinder turbocharged, direct injection diesel.

The manual that came with the 8-cyl Cat 3208 in my motor home (1300 lbs and 610 cubic inches of the finest Detroit cast iron... ) says it burns 1 gallon per hour at idle.
