Group II/II+ EHC™ base stocks
We are committed to investing in Group II/II+ products through projects such as the expansion of our Baytown refinery, construction of our Group II facility in Rotterdam and the recently completed Singapore base stocks refinery expansion that brings enhanced-performance EHC™ base stocks to Asia Pacific. In April 2019, a further multibillion-dollar expansion of the integrated manufacturing complex in Singapore was announced, with start-up anticipated in 2023. These investments allow us to offer formulation and supply-chain flexibility around the world.
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.
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
- Offer cost savings through blending optimizations
Major refinery expansions offerimproved global supply of enhanced base stocks.

Our products are designed to meet the industry’s evolving specification requirements, providing quality you can rely on today and tomorrow.
(a) In lieu of standard test method, alternate test methods may be used for the certification of a product property.
Note 1: Products are certified on release to meet the values specified. Actual values may deviate within the established reproducibility of the test method specified.
Note 2: For purpose of determining conformance with specification, observed or calculated values shall be rounded off to the nearest unit in the last significant digit used in expressing the limiting value in accordance to the ASTM E 29 method
