What kinds of automobile oils are there?

There are three kinds of automobile oils, mineral, semi-synthetic and fully synthetic. Mineral oil is the most basic and cheapest engine oil, the grade is generally below SJ, and it is only suitable for low-grade cars or some new cars. Blending semi-synthetic oil with synthetic base oil is generally suitable for non-turbocharged mid-range vehicles. Fully synthetic oil has good resistance to high temperature volatilization and deposition, and is suitable for engines with high temperature, high speed and high compression ratio, such as turbocharged engines.

Fully synthetic oil is a real chemical synthetic engine oil, which can maintain excellent lubricity even when other base oils fail, and its price is the most expensive among the three types of engine oils.

The use of engine oil depends on the condition of the car. If the car is a weather-beaten classic car, you need to buy more expensive engine oil to maintain the car, but if the car is a new car, there is no need to buy expensive best engine oil at all, just buy ordinary gasoline.

Therefore, different oils can be selected according to the situation of the vehicle. Only by choosing the right engine oil can the vehicle start better and run more smoothly. Otherwise, tampering with the oil will hurt the vehicle and shorten its service life, which is very bad.
