1. Good oxidation stability: slow down the oxidation and deterioration of engine oil under high temperature, low temperature and various harsh working conditions, hinder the formation of acidic substances, and extend the service life of engine oil.
2. Low volatility: maintain low volatility when running at high temperature, reduce lubricant consumption, and thus reduce the number of times lubricant is added.
3. Good viscosity-temperature characteristics: The viscosity index is a value that measures the change of lubricant with temperature. The larger the value, the smaller the change of viscosity with temperature. That is to say, the lubricant does not thicken significantly at low temperature, affecting the start of the vehicle; the lubricant does not become thinner significantly at high temperature, affecting the adhesion and high shear resistance of the oil film.
4. Excellent cleanliness and dispersibility: prevent the formation of carbon deposits and accumulation at the piston ring, avoid the formation of sludge, and fully suspend the cleaned dirt in the oil, filter it out through the filter, and ensure the cleanliness of the lubrication system.
5. Good wear resistance: provide a protective film to the machine parts to avoid wear of the machine parts under harsh working conditions.
6. Anti-foaming: Prevent the formation of foam in the lubricating oil and cause the oil film to rupture, thereby reducing the protective function of the lubricating oil.
