Synthetic oil is good for vehicles,it gives best performance in winter season.Synthetic oil is a lubricant consisting of chemical compounds that are artificially made.It can also be synthesized from other raw materials. Synthetic oil is used as a substitute for lubricant.Synthetic motor oils are man-made oils as-polyalphaolefin,
,Hydrocracked/Hydroisomerized.Semi-synthetic oils (also called 'synthetic blends') are blends of mineral oil with no more than 30% synthetic oil designed to have many of the benefits of synthetic oil without matching the cost of pure synthetic oil.The advantages of synthetic motor oils include:-
Measurably better low- and high-temperature viscosity performance.Better chemical & shear stability.
3.Decreased evaporative loss.
4.Improved fuel economy in certain engine configurations.
5.Better lubrication during extreme cold weather starts.
6.Longer engine life.
7.Does not contain detergents..
