Oil is the lifeblood of an engine. It is the component that cools and lubricates the engine. Nowadays, more and more car owners realize the importance of oil, but they know little about the correct use of oil.

As we all know, oil is extremely important for the movement of the engine, because it shoulders the two functions of lubrication and heat dissipation. So, at any time, for the engine, don't run out of oil. But adding too much (beyond the upper limit of the scale) can have bad consequences. When the oil is too much, it will increase the rotational resistance of the crankshaft, reduce the output power of the engine, and the excess oil will enter the combustion chamber to participate in combustion, causing the vehicle to burn oil, smoke blue smoke, and even increase the fuel consumption. The residue of oil combustion (which is mostly carbon and very hard) can build up on the walls of the combustion chamber, reducing space, reducing the compression ratio of the engine, and increasing cylinder and piston wear and thus reducing the life of the vehicle.

When adding oil, keep it slightly below the mark on the oil ruler. In addition to master the type of oil, season, climate, engine displacement, technical performance and many other factors. Therefore, choose a professional car maintenance center, after careful judgment of the vehicle, choose the appropriate oil, and carefully operate in the maintenance process, to prevent potential faults. Of course, the general car maintenance center maintenance oil will not add (cost control), but if it is your own oil, the car maintenance center will not care too much, then you should pay attention not to add lubricating oil.
