EHC™ base stocks

EHC™ base stocks are part of a global Group II slate as defined within API/ATIEL guidelines for formulation and qualification of automotive and engine oil lubricants. With base oil interchange and viscosity grade read-across capabilities, EHC base stocks offer broad coverage that enables supply chain flexibility and simplified qualification testing requirements.

EHC base stocks may also be used in industrial and other applications where formulations benefit from increased oxidation stability and higher viscosity index (VI). Our rigorous processes ensure reliable delivery of consistent quality base stocks.

Key benefits

Consistent quality to help formulators produce high-performance blends that:

  • Meet or exceed industry requirements
  • Achieve optimum additive solubility and oxidation stability
  • Meet or exceed engine oil quality requirements
