Odometres do not tell the tale, hours do.
actually, gallons burned/consumed do...I think.
Before I left the truck selling (Commercial...medium duty through class 8), some of the larger trucks were starting to monitor gallons of fuel consumed as a more reliable indicator for certain maintenence/replacement items. Hours idling are different than hours at cruise/higher RPM, therefore, the amount of fuel consumed was thought to be better.
