Key Performance Benefits
Application
HiTEC® 5777, a dispersant olefin copolymer viscosity index improver, demonstrates unique performance in today's diesel engines. It provides superior protection against soot-related wear and oil thickening. HiTEC® 5777 prevents wear through two independent mechanisms. First, it is more shear stable than most conventional viscosity index improvers, maintaining its original formulated properties. This makes it more capable of protecting moving parts from abrasive soot particles. Second, HiTEC® 5777 forms a protective film on metal surfaces under pressure, a feat which non-dispersant viscosity index improvers cannot accomplish. This film, which is different from the film created by normal antiwear additives, remains durable even in the presence of soot.
