Engine maintenance essential how to choose winter lubricating oil

In winter, car maintenance is essential. If the car is not properly maintained before the winter, it will cause very serious wear and tear, which is equivalent to the amount of wear for more years of normal maintenance.

How can I choose the right lubricant product for my car?

The temperature drop is more obvious in autumn and winter, and ordinary lubricating oil products become thicker when the temperature is low, and the fluidity is weakened. It takes longer time to reach the parts that need lubrication, which makes the vehicle difficult to start and increases wear. Therefore, in autumn and winter, it is best to choose lubricating oil products with low base oil viscosity and low pour point, so as to continue to bring good lubrication to the car engine.

Dong Xia General Motor Oil is the first choice:

First of all, the selection of lubricating oil should be based on the requirements of the engine. Neither high-grade engine oil can be used on engines with lower requirements, nor can lower-grade engine oils be used on engines with higher requirements. The choice of lubricating oil can be increased by one level on the basis of the manufacturer's recommendation, or the performance of synthetic motor oil can be better.

Secondly, you should try to choose winter and summer universal motor oil. General-purpose motor oil can maintain stable lubricating performance regardless of temperature changes, and plays a better role in protecting the engine.

Again, depending on the condition of the engine. If the engine is new or in good condition, it should be able to use low-viscosity oils, such as 0W-40, 5W-40, and 10W-40, to make the flow of lubricating oil faster and reduce wear during startup.

Finally, if it is in a high-temperature season or the engine has been worn to a certain degree, it is necessary to choose a high-viscosity oil, such as 15W-50, which will help to form a thicker oil film, maintain the pressure of the oil, and reduce oil consumption.

Do not add too much:

The amount of oil added is not the better. If there is too much lubricating oil, it will increase the rotation resistance of the crankshaft and reduce the output power of the engine, and the excessive oil will burn into the combustion chamber and burn, causing the vehicle to burn engine oil and emit blue smoke, so that the fuel consumption increases. The residue after the combustion of oil will accumulate on the combustion chamber wall, reducing the combustion chamber space, thereby reducing the compression ratio of the engine; at the same time, it will also accelerate the wear of the cylinder and piston, thereby reducing the service life of the vehicle. Therefore, when adding lubricating oil, it is appropriate to keep it slightly below the maximum scale of the oil dipstick; in addition, it is necessary to grasp the type of engine oil, the season of oil change, engine performance and many other factors.
