[Auto Repair Knowledge]What is synthetic motor oil?

Engine oil is divided into two categories: semi-synthetic engine oil and fully synthetic engine oil. The biggest difference between the two is that: Fully synthetic oils can be used at a wider temperature and have a longer service life; the same oil film requirements, synthetic oils can be achieved with lower viscosity, while semi-synthetic oils need to be thicker than synthetic oils. The viscosity can meet this requirement. In other words, in the same working environment, fully synthetic oil can achieve the purpose of protecting the engine with a lower viscosity. Similarly, in the same working environment, fully synthetic oil has a much longer service life than semi-synthetic oil, so although the cost is higher, after comparing the number of oil changes, it is not much higher than mineral oil.
Compared with semi-synthetic engine oil, fully synthetic engine oil has the following characteristics:

1. Fully synthetic engine oil has better high and low temperature performance;

2. There is a longer oil change interval;

3. Suitable for more severe vehicle conditions.
