Maintenance is done by cleaning the lubrication system. Is it necessary to clean the engine lubrication system?

I believe riders have a certain understanding of the lubrication system, which, as the name suggests, plays a role in lubricating internal parts. So when it comes to the question of whether to clean or not, everyone has slightly different views. Some friends have reported that their car has been used for almost 10 years and has not been washed once, and the car is still intact. Is that true? Is it necessary to clean the engine lubrication system?

In fact, it is necessary to clean the engine lubrication system. Why do you say that? Although the filter can effectively filter some impurities, but who can ensure that "dripping water does not leak", more or less some particles will enter the oil pipeline. Long-term use will definitely deposit sludge, grease, gum, and carbon deposits, and it is easy to block the pipeline, and even accelerate the deterioration of the lubricating oil, causing the lubrication system to fail to work properly. Not only will it increase the degree of wear of the engine parts, but also the phenomenon of cylinder explosion, so everyone should not believe the rumors that they will not be cleaned for 10 years.

As for how often the lubrication system is cleaned, it is usually cleaned every 20,000 kilometers. Of course, we also need to see what kind of oil your car usually uses. If mineral oil or semi-synthetic engine oil is used for a long time, the cleaning cycle should be shortened appropriately. If you use a fully synthetic engine oil with better working conditions, you can naturally extend the cleaning cycle, which is about 25,000 kilometers.
