Viscosity Index Improvers
Introduction
GL
3015 is Cost-effective OCP viscosity modifier to meet global needs. A
non-dispersant olefin copolymer viscosity modifier it is specially
engineered to provide low-temperature performance while maintaining
excellent film strength and engine test performance.
GL
3015 is an oil concentrate of an olefinic copolymer and is
recommended primarily as a Viscosity Index Improver for crankcase
lubricants particularly where excellent shear stability is desired.
As
applies to all viscosity index improvers, there is some loss in
viscosity and in viscosity index due to the shear forces encountered
in engine operation. In this respect, GL 3015 exhibits outstanding
characteristics as evidenced by an average viscosity loss of 14 % at
100° C for SAE 15W-50 crankcase oils in over the road service.

Applications
Recommended for use in suitable base stocks to prepare multi grade
crankcase engine oils. Approximate treatment levels for stay-in-grade
(10-hour CRC L-38 Test) performances are
Actual treatment levels depend on the
performance package and base stock used. A blend study is required to
modify the treatment level for a particular formulations.
