How much gas does a moving truck use?
Quick Answer
Moving trucks get 6 to 12 miles per gallon depending on size: 10-foot truck (12 mpg), 15-foot (10 mpg), 20-foot (8 mpg), 26-foot (6-8 mpg). For a 1,000-mile move in a 20-foot truck, expect to spend $400 to $550 in fuel.
Fuel is one of the biggest hidden costs of a DIY move. Moving trucks are heavy and not aerodynamic, so fuel economy is poor compared to a car.
Fuel economy by truck size: 10-foot truck: 10-12 mpg. 12-foot truck: 10-12 mpg. 15-foot truck: 8-10 mpg. 17-foot truck: 8-10 mpg. 20-foot truck: 7-9 mpg. 22-foot truck: 6-8 mpg. 26-foot truck: 6-8 mpg.
These are approximate and vary based on: load weight (heavier loads reduce mpg), terrain (mountains reduce mpg significantly), driving speed (55 mph is much more efficient than 70 mph), weather and wind (headwinds reduce mpg), and whether you are towing a vehicle (reduces mpg by 10-20%).
Fuel cost estimates for common distances (using average gas price of $3.50/gallon): 500-mile move in a 15-foot truck: ~55 gallons = ~$190. 500-mile move in a 26-foot truck: ~75 gallons = ~$260. 1,000-mile move in a 15-foot truck: ~110 gallons = ~$385. 1,000-mile move in a 26-foot truck: ~150 gallons = ~$525. 2,500-mile move in a 26-foot truck: ~375 gallons = ~$1,310.
Fuel-saving tips: drive at 55-60 mph (sweet spot for trucks), avoid rapid acceleration and hard braking, keep tires properly inflated, remove the roof-mounted air deflector if not towing, and plan fuel stops along the route (use GasBuddy to find cheap stations). Diesel trucks (Penske fleet) may get slightly better mileage and diesel prices vary by region.
Return fuel policy: most companies require you to return the truck with the same fuel level. If you return it low, they charge $5-$8 per gallon for refueling. Always fill up near the drop-off location.
