Mack Trucks announced that following extensive truck and engine testing, it has approved the use of renewable diesel fuel in all Mack engines. Similar to conventional biodiesel, renewable diesel fuel is derived from biomass feedstocks, including animal fats and oils. Unlike biodiesel, renewable diesel fuel is produced using a different process and maintains physical properties and performance similar to petroleum diesel, meeting the same ASTM D975 standard, the company said.
“As the availability and customer requests for renewable diesel fuel increase, we worked to ensure its compatibility with our engines,” said Stu Russoli, Mack highway and powertrain products marketing manager. “This approval gives Mack customers who seek to reduce their environmental footprint an additional choice when it comes to alternative fuels.”
The addition of renewable diesel fuel adds to Mack’s alternative fuel offerings. The Cummins-Westport ISX12 G natural gas-powered engine is currently available in Mack Pinnacle DayCab model. The Mack LR and Mack TerraPro cabover models also offer natural gas options with the availability of the Cummins-Westport ISL G engine.
