Base Oil Division

Base Oil, both Virgin & Re-Refined ( Recycled ) grades of SN150, SN300, SN500 are being exported in Flexitanks..

Base Oil Division

Base stocks are called by several names: Neutrals (SN100, SN150, 6SN650,) &Bright Stocks, Grades (SAE 5, 10…; ISO 22, 32..).

Base Oil Division

The most common names are for group I (SN: Solvent Neutral), for group II (N: Neutrals) and group III grade names refer to the viscosity (4cst, 6cst, 8cst …).

BASE OIL DIVISION - Group III

 

GROUP III BASE OIL

Group III base oils are subjected to the highest level of mineral oil refining of the base oil groups. Although they are not chemically engineered, they offer good performance in a wide range of attributes as well as good molecular uniformity and stability. They are commonly mixed with additives and marketed as synthetic or semi-synthetic products. Group III base oils have become more common in America in the last decade.

Grades - 60N , 70N 100N 150N  and 250N   named according to their viscosity(cSt) at 100

These products are very high VI base oils produced under all-hydro processing route (hydro cracking, wax hydro isomerization and hydro finishing). The  isomerization process and severe hydro cracking and hydro finishing process almost completely removes impurities and saturates aromatics to only a traceable level.

These base oils are also claimable as “synthetic” according to the ruling by the National Advertising Division (NAD) of the Council of Better Business Bureaus and have the following characteristics, which closely match conventional synthetics like PAOs.

Very high viscosity index
Excellent response to PPD
Low temperature performance
Oxidative and thermal stability
Low volatility
High flash points and purity
