Mack Trucks has signed off on the use of renewable diesel fuel in all Mack engines after extensive truck and engine testing, the company announced.
Similar to conventional biodiesel, renewable diesel fuel is derived from biomass feedstocks, including animal fats and oils. However, 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.
Renewable diesel fuel offers several environmental benefits to customers, including reducing particulate matter. A life cycle analysis of renewable diesel fuel conducted by the California Air Resources Board also demonstrated reductions in greenhouse gases by 15 to 80%, depending on feedstock source used.
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 the 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.
