For most owner-operators and small fleets, fuel is the largest cost after the truck itself. You cannot control the price at the pump, but you can control how much you buy and where.
Idling
An idling truck burns fuel without moving freight. Over a year, a few hours a day adds up to hundreds of gallons. Auxiliary power units, bunk heaters and shore power can cut it, and many states and cities limit idling.
Speed
Fuel economy drops as speed goes up. Running a few miles an hour slower on long runs usually costs little time and saves a lot of fuel.
Tires and maintenance
Underinflated tires and poor alignment waste fuel. Check pressure regularly and keep up with maintenance.
Where you buy
Plan fuel stops around price, use a fuel card or discount program if it fits, and keep every receipt for IFTA.
Measure it
Track miles per gallon by truck every month. If a number drops, something changed.
