Car maintenance guide, what is the difference between fully synthetic motor oil and semi-synthetic motor oil?

Normally, the oil should be changed every 5,000 kilometers. If you drive more often, you should change the oil more often. Many people think that the more expensive the oil, the better. In fact, this is not true. If it does not match, Mobil will also damage the car.

 

Mineral oil is not recommended. Basically, full synthetic oil and semi-synthetic oil are chosen. Semi-synthetic oil does not perform well in low temperature environments, and the oil change cycle is short. Generally, it needs to be changed every 5,000-7,000 kilometers. A small amount of sludge will appear after long-term use. The price is cheaper than full synthetic oil and it is more suitable for daily use of common stocks.

 

Full synthetic oil has better stability and fluidity. It is usually changed after more than 10,000 kilometers. It is not easy to produce sludge, but the price is high and the cost performance is low.

 

Considering the long-term maintenance of the car, full synthetic oil is better, especially in our Northeast, where the winter is cold. Full synthetic oil is also stable at low temperatures and can better protect the engine.
