Group III
Base Oil Group III 2 cSt
Light Group III base oil, the 2 cSt viscosity class, for low-viscosity lubricants.
What is Base Oil Group III 2 cSt?
Group III 2 cSt base oil is the lightest high-viscosity-index base oil in the Synergysol Trading range. The grade name is the kinematic viscosity class at 100°C. API Group III base oils are severely hydroprocessed: viscosity index of 120 or higher, saturates of at least 90%, and sulfur of 0.03% or below.
Lubricant blenders use Group III base oil 2 cSt in low-viscosity engine oils, shock-absorber fluids, and light industrial formulas. The 4 cSt grade is the next class. Group II N70 is the light Group II grade.
Applications
Synergysol Trading supplies Group III 2 cSt base oil for light lubricants that specify a high viscosity index.
Low-viscosity passenger-car engine oils. Light engine-oil formulas use the 2 cSt class when the base oil is Group III.
Shock-absorber and specialty hydraulic fluids. These fluids name a light, high-viscosity-index base oil.
Light process and industrial oils. Process oils that have moved to Group III start at this class.
Named 2 cSt formulas. Where the specification says Group III 2 cSt, this is the base oil on the order.
