Heavy Duty Transmission Fluids

To meet the Paris Agreement’s climate goals, commercial vehicles need to reduce emissions by 80% by 2050. The European Union has set CO2 reduction targets of 15% by 2025 and 30% by 2030 for commercial vehicles. To reach these goals, heavy-duty transmission fluids are moving toward lower viscosity – currently 10-14 cSt kinematic viscosity (KV) @ 100°C but trending lower – while striving to maintain, and even improve, wear protection and durability. 

Achieving these lubrication goals is especially difficult for heavy-duty vehicles, which must cope with higher shear, higher temperatures and higher wear compared to passenger vehicles. Increasing drain intervals from 300-500K KM to the target goal of 1M KM requires innovative formulations.
