At present, the market a lot of brand lubricants, car owners in the maintenance of the car, most of the manufacturers will recommend bulk lubricants, the lubricant is based on the manufacturer's cylinder seal and the need to lubricate the gap size, commissioned Lubricants manufacturers, very targeted.

Lubricating oil five levels:

Gasoline engine lubricants can be divided into SE-SL five levels, the more the quality level of the higher, the better lubrication performance. Suzhou lubricants have its own car to adapt to the level of oil, the owner if you choose not to use the lubricant below the level prescribed by the car manufacturers lubricants, but also according to the weather to choose the appropriate viscosity of the oil. After the new car and overhaul of vehicles to try to choose high quality oil, viscosity should choose low, so that the running of the car will be more beneficial, you can choose 40 or 15W / 40 of lubricating oil, to remind owners, do not add repair Agent or fuel-saving products to prevent the occurrence of axle burning bush accident.

The number behind the oil level varies from 5 to 50, the bigger the number, the more sticky the oil, and the thinner it is.

Summer try to choose a large viscosity oil, such as 40,50 and so on. Because the viscosity of lubricating oil changes with the temperature changes, that is, the viscosity of lubricating oil decreased when heated, deterioration of oxidation resistance, perishable, and even caused by burning Waqiang axis failure. Therefore, the crankcase and gear box should be replaced by a larger viscosity of summer lubricants.

In addition there is a wider use of multi-grade lubricants with "W" that it adds a polymer polymer material, in addition to the general characteristics of lubricating oil, the viscosity can be adjusted within a certain range, when the heat becomes thicker, If the cold become thinner, this will reduce the resistance and wear of the engine. Summer car can choose 20W / 50 of lubricating oil.
