Synthetic? Mineral? Or maybe intermediate?

Mineral oils are formed as a result of refining vacuum residues from petroleum distillation through selective refining with solvent, dewaxing and deasphalting and finally through additional final hydrogen purification to obtain mineral base oils. Base oils are used for production of final products after having added quality and viscosity improver additives.

Synthetic oils are produced in an artificial way, by way of chemical processes.  They are obtained through synthesis from simple chemical compounds, e.g. by way of gas petrochemical processing. In the process of production they are subject to more advanced processes of production and this means that the entire process is more expensive. However, additional costs are compensated by better properties obtained:

  1. Synthetic oils may work longer at high temperatures
  2. They ensure better resistance to oxidation than mineral oils, which leads to smaller consumption and longer life of the engine.
  3. They ensure longer intervals between oil change
  4. They ensure faster full lubrication and circulation of oil when starting the engine, which leads to smaller wear and tear of engine elements and fuel consumption (this property of oils results from lower viscosity of oils at low temperatures and smaller dependence of oil viscosity on temperature).
  5. Lower viscosity of oils at low temperatures and smaller dependence of oil viscosity on temperature results in a possibility to manufacture multi-season oils having wider viscosity range which are required by modern engines in order to provide long intervals between oil changes, multi-seasonality of universal application in all climatic conditions, reduction of fuel consumption and emission of harmful substances.
  6. Higher resistance of oil film and therefore smaller wear and tear of the engine.
  7. Higher stability and lower volatility at high temperature reduces the oil consumption

Synthetic oils which are mixtures of mineral oil and up to 30% of synthetic oil are a compromise solution. Being mixtures of synthetic oils with mineral oils, they show higher quality as compared to plain mineral oils.
