What is special about motor oils with esters?

Esters (esters) are a synthetic product that can be part of the base of 3 types of base oils:

  • HYDRO CRACKED BASE (HC)Hydrocracking base: is not a completely synthetic product, since to a greater extent it is mineral oil, which has undergone certain processing to obtain the desired properties of synthetic oils. Such oils have a high lubrication coefficient, but are more volatile compared to PAO.
  • POLY ALPHA OLEFINS (PAO)PolyAlphaOlefins: the most famous and most popular base in synthetic and semi-synthetic oils. It has very good resistance to high temperatures and low volatility.
  • ESTHER OILSESTERS: in the composition of base oils, this component makes them the best for operation. They easily cope with the standard tasks of motor oils and provide the best characteristics, even in difficult conditions.
