What maintenance items do you need to do for a car with 30,000 kilometers?

30,000 km car maintenance projects include oil replacement, oil filter, air filter, fuel filter, throttle cleaning and spark plug replacement. Some 4s stores will require other maintenance items, and the owner will consider maintenance according to the actual situation.

It is necessary to change the oil and oil filter. Because the oil in the harsh environment of high temperature and high pressure, the shelf life will be greatly shortened, the performance will be greatly reduced, and the engine will not be protected over time. In order to prevent impurities from mixing into the oil and causing oxidation, the oil filter element produces colloid and sludge to block the oil circuit. And the oil filter element are replaced at the same time. The air filter is replaced every 10- 15000 km, and the fuel filter is replaced every 30000 km.

The throttle valve needs to be cleaned for the maintenance of 30,000 kilometers, and it is not needed before 30,000 kilometers, so it can be rejected. The vehicle has traveled at least 30,000 kilometers for a while. At this time, there will be more carbon deposits in the throttle, which will lead to a smaller throttle opening, and then there will be unstable idle speed and weak acceleration. If the owner feels that the power of the vehicle decreases during this period, then the throttle and spark plug should be considered when maintaining.

The spark plug should be replaced after 30,000 kilometers, provided that it has not been replaced before 30,000 kilometers and has not completely lost its function on the spark plug, but the ignition performance of the spark plug is greatly reduced, which directly affects the power, performance and fuel consumption of the engine. If you think the vehicle is running well, you can extend 1 10,000 kilometers.

In addition to these items, the 30,000-kilometer maintenance also involves the inspection and maintenance of dozens of items such as engine, gearbox, air conditioning system, steering system, braking system, suspension, body and tires. Remind the owner to read the maintenance list carefully before maintenance, and there is no need to do any unnecessary items. Million car purchase subsidy
