Is it necessary to do engine cleaning for a new car?

Vehicles that have not been cleaned and maintained for a long time, have a long oil change cycle, and have poor road conditions, or vehicles that have traveled for 40-50 thousand kilometers are recommended to be cleaned.

The internal cleaning of the engine in everyone's mouth should refer to cleaning the sludge and carbon deposits in the engine. When using a car at ordinary times, using some "fuel additives" regularly can solve some oil problems. In fact, the new car just traveled 20-30 thousand kilometers and didn't have as much carbon deposit as expected. What about the cleaning of engine sludge?

In view of the mileage of your vehicle, it is almost unnecessary to clean the inside of the engine if there is nothing unusual in the driving process of your vehicle, especially for vehicles with short mileage.

So is it necessary to clean up the sludge specially?

Many repair shops and 4S shops will definitely hang some pictures of serious engine sludge or show them to you, so that you can make what he called "engine internal cleaning package". But the real situation is that in addition to lubrication, the current engine oil also has a cleaning component, which can effectively take away the dirt in the engine. As long as there is no problem with the quality of the oil used and it is maintained regularly, there will be basically no problem.

Some car owners have bad maintenance habits. The cleaning and lubricating effect of the oil will be greatly reduced if the oil is used beyond the time limit and is not replaced after the expiration, or if the oil has deteriorated. After a long time, the sludge and carbon deposit inside the engine are no longer just a little bit.

Sticking sludge to the cylinder wall will also increase friction, resulting in high fuel consumption. At the same time, dirty oil will cause insufficient oil pressure, which will lead to the failure of valves with hydraulic tappets, and cause abnormal engine sound, unstable idle speed, engine power decline and other failures. Although ordinary engine oil has cleaning function, once sludge is produced, it will not be discharged when replacing the engine oil, and it will pollute the new engine oil.

For some cars that have not been cleaned and maintained for a long time, the oil change cycle is long, the road conditions are not good, or the cars that have traveled for 40-50 thousand kilometers, it is impossible to keep the engine clean simply by changing the oil. At this time, it is necessary to clean and maintain the engine comprehensively.
