OCP Viscosity Index Improver


HiTEC 5748 additive is an olefin copolymer (OCP) VI improver recommended for use in gasoline and diesel engine lubricants, particularly when excellent shear stability and high-temperature, high-shear-rate viscosity is desired. HiTEC 5748 additive exceeds the ACEA shear stability requirements, even in wide-span viscosity grades. HiTEC 5748 additive is also a suitable viscosity index improver for use in certain industrial lubricants that require a high degree of shear stability.

Recommended Dosage

Dosages generally recommended to make the various multigrade viscosity crankcase oils are as follows:

 SAE Grade 10W30 10W40 15W40 15W50 20W40 20W50
 HiTEC 5748 Additive, %wt. 7.5 11.0 9.0 12.5 4.0 7.5
