Synthetic oils are organic compounds that are widely used as lubricants for various types of engines and mechanisms. Sometimes synthetic oils can be used as a heat transfer fluid.
Synthetic oils are characterized by a flat viscous-temperature curve, low volatility, resistance to low temperatures and, at the same time, fire resistance, high lubricating properties, chemical, thermal stability and radiation resistance. In particular, chemical stability is expressed in the fact that when interacting with other substances during engine operation, synthetic oils do not undergo oxidation, waxing and other processes that impair its performance. The thermal stability of synthetic oils is their ability to maintain optimal viscosity over a wide temperature range, which allows you to start the engine, for example, in cold weather, and then work at high temperatures at high speed and under heavy loads.
As practice shows, sales of synthetic motor oils peak in autumn. It is at this time, thanks to them, that it is possible to achieve the necessary low-temperature characteristics with less effort. In addition, in comparison with mineral oils, synthetic oils have a higher viscosity index, better fluidity, greater aging resistance, less volatility, better antifriction properties and increased resistance to shear deformation.
Synthetic oils can also be distinguished by the absence of problems during cold start of the engine, more economical fuel and lubrication consumption, reliable protection against high-temperature deposits.
Synthetic oils reach engine parts faster after a cold start, thus ensuring less wear and tear.
