There are two aspects to consider when choosing the engine oil of FAW-Volkswagen Magotan. One is the brand of the engine oil: 1. The car is 1W-4, and the other is the grade of the engine oil. Please carefully check the grade of the engine oil used in your car and choose it strictly according to the regulations. 2, the choice of brand of engine oil, must take into account the regional environmental temperature. The area south of the Yangtze River can use more than 1-15w-4 engine oil all the year round; 3. In Northeast China, choose 1-15w-4 engine oil in summer and -5w-3 or 4 engine oil in winter; 4. The smaller the viscosity of the engine oil, the thinner the engine oil will be, and the greater the mechanical wear will be. The purpose of the low viscosity of the engine oil is to facilitate starting. After the engine starting temperature comes up, it is still good for the machine with high viscosity! Therefore, under the condition that the engine can be started normally, the greater the oil viscosity, the better; 5. There is a famous saying in our automobile maintenance: saving oil and saving oil, which is the contradiction of oil selection. When selecting engine oil, we must adhere to the principle of "saving shaft".
