- Offers dispersancy performance in both gasoline and diesel engines
- Excellent shear stability capable of meeting European requirements
- Excellent engine cleanliness in field testing
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.
Max Handling Temp: 250°F (120°C)
Shelf Life: 36 months @ ambient temperature
Dosages of HiTEC® 5777 are generally recommended to meet the 10 hour L-38 stay-in-grade requirements for API specifications are given below. Recommended supplemental dosages to meet the more severe ACEA specifications are given in parentheses.
