1, oil change
Engine oil is actually lubricating oil. There are many kinds of lubricating oils, such as engine lubricating oil, gearbox lubricating oil, brake oil, steering power-assisted oil ... When we say engine oil, we usually refer to engine lubricating oil.
According to the type of engine oil, it can be divided into three categories, namely, ordinary engine oil and mineral oil, semi-synthetic engine oil and all synthetic engine oil. When maintaining and changing oil, as long as the word "synthetic" is not used, it is all "ordinary" engine oil and mineral oil.
Engine oil type and maintenance interval
The lubricating effect of engine oil will have a certain time limit. Under normal circumstances, it will begin to oxidize and rot after being exposed to the air for about 3 months. Generally, "ordinary mineral" engine oil begins to oxidize and decay at 5000 kilometers. Semi-synthetic engine oil is about 7500 kilometers, and synthetic engine oil is about 10000 kilometers. Therefore, the oil change time depends on the mileage first.
2. Maintenance of air filter element
Automobile air filter is the first line of defense for air to enter the engine, which filters impurities in the air under the action of filter paper. When air impurities block the filter holes of the filter paper itself, it will directly affect the normal power output of the automobile engine, and the consequences are unimaginable.
The air filter is a component that is in direct contact with the outside world and is easily blocked. When blocked, the engine will have symptoms such as weak acceleration and unstable idle speed. The normal operation of the air filter can avoid the premature wear of the engine and keep the best working condition. It is best to change the air filter every 20,000 kilometers and check it once every 65,438+00,000 kilometers.
3. Automobile interior
The car reflects the owner's taste, keeps the car dry and hygienic, especially for the sanitary corners such as car cushions and air outlets, and does a good job of antibacterial work in the car.
Usually, you can use the sterilization deodorant of the automobile air conditioning system, which can remove the dirt from the evaporator of the air conditioning system, solve the odor problem of the air conditioning outlet and protect your health. We remind car owners that when cleaning the interior of their cars,
Use neutral detergent for cleaning, and never use substances with strong acid and alkali. In addition, attention should be paid to avoid corrosion of electrical equipment such as audio, radio and CD when cleaning.
4, car paint maintenance
The common sense of car paint maintenance is actually very complicated. Although the car paint looks smooth, there are tiny concave surfaces and holes on the surface. It is recommended that the new car be glazed or painted once.
Generally speaking, coating takes longer than sealing, the sealing effect is about 3 months to half a year, and coating is more than half a year. It is suggested that secondary sealing or coating is needed after a certain period of time. The routine projects carried out by car wash shops are polishing and waxing.
However, these two items should be carried out on the premise of painting or sealing glaze, because always waxing or polishing is equivalent to consuming the thickness of the paint surface, which makes the paint surface gradually thinner, lose luster and appear tiny scratches.
There are also many places to pay attention to in the daily maintenance of automobile paint.
First, avoid wiping the paint surface directly with a rag or dry cloth. After washing the dust and dirt off the car surface with water, wipe it clean with a clean absorbent cloth. Don't air dry yourself after washing.
Second, when parking, you should consider avoiding long-term sunlight, especially white and non-metallic paints.
Third, reduce the number of car washes and try not to wax and polish vehicles.
Fourth, pay attention to the timely removal of corrosive things such as bird droppings.
Fifth, when driving, pay attention to reducing to corrosive areas, such as the seaside, the pavement sprinkled with snow melting agent, and the newly paved asphalt road.
Sixth, after running high-speed in summer, the insect bodies that hit the front of the vehicle should be cleaned up in time. If it is not cleaned in time, the paint surface of the vehicle will be corroded in a short time.
5, car tire maintenance
Automobile tires and rims are the most easily dirty parts. Therefore, tire maintenance is also a very important key. Prepare a long-handled brush before washing the tires. If the tire is not too dirty, just wash it with a general cleaner. Unless there is really too much dirt, you may want to buy a professional cleaner.
Chrome-plated mirror-treated rims can't be brushed, which will leave obvious scars. Sponge is generally used for chrome-plated wheels, and then consider using a brush when washing small places. As long as the tires and the parts below the knee are cleaned, the optical fiber of the whole vehicle will look very bright.
