USPS contractor McAbee Trucking purchased eight propane Autogas-fueled Ford F-750 delivery trucks that are contracted for parcel delivery routes between USPS locations in North and South Carolina.

This marks the first time that some U.S. Postal Service packages are being delivered via propane autogas trucks. Each of McAbee’s trucks is equipped with a Ford 6.8L V10 engine and Roush CleanTech propane fuel system, which is 90% cleaner than the Environmental Protection Agency’s most stringent heavy-duty emission standard, according to Roush.

To fuel its new fleet, the company will install a propane station onsite. Until then, McAbee Trucking has onsite “mobile fueling,” where its local propane supplier fuels the vehicles from a propane delivery truck.

“Propane is really a great fit for the size and duty cycle of the trucks we use in our business,” said Lisa McAbee, owner of McAbee Trucking.

Propane fleets report savings of 30 to 50% on filters and fluids due to the clean operation of the fuel, Roush said.

McAbee Trucking and Roush CleanTech unveiled the new propane delivery trucks during The Work Truck Show in Indianapolis. During the show, ROUSH CleanTech also received Heavy Duty Trucking’s Top 20 Award for the second year in a row. This award recognizes the company’s near-zero emissions vehicles.
