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. 



Grades - *0N & **0N   named according to their viscosity (cSt) at **0℃.

These products are very high 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 remove impurities and saturate 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
