Bison Transport decided to try POWERGUARD (TM) D4 in their highway trucks and reefer/heater units to help reduce their fuel and cold weather related diesel engine issues. Recognizing the benefits of using advanced detergents, fuel stabilization and effective cold weather protection, Bison Transport switched to the all-season, 100% active, multi-component POWERGUARD (TM) D4 from Innospec Fuel Specialties.

“We saw a dramatic decrease in the number of fuel related maintenance issues we had been accustomed to seeing and this, over a winter where temperatures were exceptionally cold. We are extremely pleased with the performance of POWERGUARD (TM) D4 and would not hesitate to recommend its use.”

Jeremy Gough, Director of National Fleet Maintenance
