Every owner knows that a new car is serviced every once in a while after it has been taken home. However, due to the late popularization of domestic family cars, many car owners have limited knowledge of car maintenance, and even many people think that as long as they can drive, everything will be fine, and those professional things should be handed over to professional people to do. Therefore, under the recommendation of the auto repair shop, I spent a lot of unjust money and did some very chicken projects.
Some of the most useless items in car maintenance
First, the engine cleaning project
There are many car owners who think that the projects related to the engine must be done, but in fact, for new cars with a short driving range, cleaning the engine is completely unnecessary. Therefore, many auto repair shops are also very perfunctory when doing this project, and only do a surface cleaning.
Second, tire maintenance
Car tires, as the parts of the body that are most often in contact with the ground, are indeed the most susceptible to wear, but this so-called tire maintenance project is actually to clean the tires once, and there is no difference between them and car washes. If the owner finds that his tire wear is more serious, he should replace the tire in time, rather than doing this useless maintenance project.
Third, clean the oil circuit
There are many auto repair shops that recommend cleaning the oil road for the owner when the owner does maintenance, and it can alleviate the increase in car carbon deposits. Although cleaning the oil circuit is not completely useless, but frequent cleaning is not necessary at all, the owner only needs to carry out it every 50,000 kilometers, or clean it up when he feels that the power is significantly reduced and the fuel consumption is increased.
A must-do item in small maintenance
First, replace the oil
Engine oil is also called engine lubricating oil, the most important role of oil is to protect the engine, play a role in reducing wear, cooling and cooling, anti-corrosion and anti-rust and other functions. The oil used for a long time will deteriorate, and the protective function will gradually fade, which will not only fail to play a normal heat dissipation effect but also produce some sedimentary substances, which will aggravate the wear of the engine. Therefore, timely replacement of oil can extend the service life of the engine, generally speaking, semi-synthetic oil needs 8,000 kilometers for a replacement, and fully synthetic oil is more durable, only 10,000 kilometers for a replacement.
Second, the filter element
When doing small maintenance, the owner usually needs to replace the oil filter, air conditioning filter and air filter of the car. Among them, the role of the oil filter element is to filter some impurities and iron filings that may exist in the car engine, so the timely replacement of the oil filter element can also play a role in protecting the engine. The air conditioner filter, as the name suggests, filters the airflow blown out of the air conditioner. The role of the air filter element is to filter the dust and impurities from the engine port. Not replacing these three filter elements for a long time will reduce the filtration function of the filter element, the air in the car will become turbid, affecting the health of the owner, and the car engine is also prone to failure, which will affect the normal use of the car.
summary:
For car owners, their cars must be in need of all kinds of care, so car maintenance has become an indispensable step to extend the service life of the car. However, when doing maintenance, the owner also needs to lift the spirit, do not be confused by the business, waste their own funds, and spend some unnecessary money.
