Base Oil Group II N500
Heavy Group II base oil for engine oils, gear oils, and industrial lubricants.
What is Base Oil Group II N500?
Base oil N500 is the heavy Group II base oil supplied by Synergysol Trading. Engine-oil, gear-oil, marine, and industrial blenders use it when the formula calls for a hydroprocessed neutral in the heavy band. API Group II is defined by saturates of at least 90%, sulfur of 0.03% or below, and a viscosity index from 80 to 120.
The Group I base oil in this commercial band is SN-500, published at 9.5–11.2 cSt at 100°C, viscosity index 89, flash point 240°C, and pour point −6°C. Group II base oil N500 is the hydroprocessed counterpart, published at 85.8 mm²/s at 40°C and flash point 265°C. Group III 8 cSt is the high-viscosity-index heavy grade, and bright stock BS-150 is 476.2 mm²/s at 40°C.
