As we know, if the viscous is low for engine oil, it's thinner and has a poor lubrication. In order to avoid this problem, many people mistakenly think that the more viscous the better for engine oil, even to judge the quality of an lubricant oil only through the viscosity, touch it with your hands, or shake it, and observe it carefully, if the viscous is high, they will think it's belong to high quality oil, and don't ask the grade of it.
Now many of people will have misuse of lubricant oil. Actually, it has suitable grade and viscosity lubricant oil for every car, not every car is suitable for high viscosity oil. Indeed, if using for a long time, the parts of the car have some wear, the gap between the friction parts is larger, and using high viscosity oil is more conducive to strengthen its sealing performance, and the effect will be better.
However, for most vehicles, considering energy saving and waste discharge, low viscosity oil is preferred.There are the following reasons:
1. High viscosity oil has poor fluidity, high starting resistance and high fuel consumption.
2. High viscosity oil is more difficult to reach the wear part than low viscosity oil at the start-up moment, which is more harmful to the vehicle cold start.
3. High viscosity oil has poor starting performance at low temperature, especially in winter, it is difficult to start the vehicle.
