Global governmental vehicle regulations call for improved fuel efficiency and reduced greenhouse gas (GHG) emissions. One of the ways to achieve these is through the use of lower high temperature high shear (HTHS) viscosity engine lubricants, alongside more modern engine design.

In this video, we look at the impact of HTHS viscosity on the following:

  • API CK-4, API FA-4 and MB 228.61 specifications
  • Fuel savings
  • Testing procedures
