What are the 30,000 km maintenance items for private cars?

The car's 30,000-kilometer maintenance project includes oil replacement, oil filter, air filter, fuel filter, throttle cleaning and spark plug replacement. Some 4s shops will require other maintenance items, and the owners will consider them themselves and carry out maintenance according to the actual situation.

It is necessary to change the engine oil and oil filter. Because the engine oil is in the harsh environment of high temperature and high pressure in the engine, the shelf life will be greatly shortened and the performance will be greatly reduced. Over time, it will not be used to protect the engine. In order to prevent impurities from mixing with engine oil and causing oxidation, the oil filter element produces colloid and sludge to block the oil circuit. Replace the oil and oil filter at the same time. The air filter should be replaced every 1- 1.5 thousand kilometers, and the fuel filter should be replaced every 30 thousand kilometers.

The throttle valve needs to be cleaned for 30,000 km maintenance, but it was not needed before 30,000 km, so it can be rejected. The vehicle travels for at least 30,000 kilometers for a period of time. At this time, there will be more carbon deposits at the throttle, which will lead to a smaller throttle opening, and then there will be phenomena such as unstable idle speed and weak acceleration.
