First, the automobile oil should be suitable.

Automobile oil includes two aspects, namely fuel oil and lubricating oil. If the car runs again, it is consuming fuel, and it is inseparable from fuel almost all the time. Once the fuel is improperly selected and used, it will easily lead to the blockage of the fuel filter and poor atomization of the fuel injector, resulting in unstable idle speed of the engine, poor acceleration, rising fuel consumption, accelerating cylinder wear, affecting the life of the engine, and naturally increasing the maintenance cost and maintenance cost of the automobile.

There are many kinds of lubricants in the market, and the quality of lubricants of different brands and grades is very different, and of course the prices are also very different. When choosing lubricating oil, should we consider whether it can meet the lubrication requirements and spend less money?

The basic principle is: as long as it can meet the requirements of vehicle use, only buy the right one, not the expensive one. For example, engine oil, for domestic cars, some domestic SJ-grade engine oil can fully meet the requirements, and there is no need to buy imported ones.

Second, use free tests to eliminate potential failures.

Car manufacturers have free testing activities. These activities are very beneficial to car owners. Car owners can take advantage of these free testing activities to conduct a comprehensive physical examination of their cars, find and eliminate some potential faults in time, thus saving high maintenance costs that may occur in the future.

Third, reasonably determine the maintenance cycle.

Car maintenance has a high position in the eyes of car owners, and they always want to do maintenance when the car is not easy to use. However, in the actual use process, the owner should refer to the maintenance cycle recommended by the automobile manufacturer, and make appropriate adjustments to the maintenance cycle in combination with the technical conditions and use conditions of the automobile itself.

Generally speaking, a new car can be used under good road conditions, and it does not need too frequent maintenance, and the maintenance cycle specified by the manufacturer can be the upper limit. However, if the technical condition of the car is poor or the service conditions are poor, the maintenance cycle should be shortened appropriately.

Fourth, minimize maintenance and assembly.

Car owners have the feeling that once the car needs maintenance, it will get out of control after disassembly and maintenance, making the car enter the maintenance period prematurely. The reason for this situation involves the repairman's assembly technology and the quality of accessories. Try to avoid the maintenance of the assembly, especially the disassembly and maintenance.

Reasonable use of all kinds of advanced technical maintenance equipment and means to carry out disassembly-free maintenance of the automobile, avoid unnecessary damage to the automobile assembly and parts, improve the maintenance quality, and thus reduce the total maintenance cost.
