DEF is a nontoxic solution of 67.5% purified water and 32.5% urea. Installations will utilize new dispenser and POS systems that will make purchasing DEF quicker, more efficient and customer friendly.

Sites will feature dedicated DEF dispensers at the fueling islands, while large storage tanks will be installed away from the fuel island.

All TA and Petro branded locations currently offer 2.5 gallon containers of DEF at all 228 of its locations, available at the fuel desk, travel store or truck maintenance counters and all of the company’s RoadSquad emergency roadside vehicles carry a supply of DEF.

TA’s on-island DEF dispenser installations will further add to current capacity; the first five locations are the TravelCenters of America in Lodi, OH and Nashville, TN (reopening February 2011) and the Petro Stopping Centers locations in Spokane, WA, Kingman, AZ and El Paso, TX. TA and Petro were the first national chains to offer DEF at all locations. Further, because nearly all TA and Petro locations offer extensive truck maintenance services, TA expects to offer DEF top-off services as part of routine preventive maintenance, or PM service to vehicles that use DEF.
