And the old policeman can see at a glance on the bus which "three hands are", experienced repair shop guys, can also see from your words and deeds whether you are a rookie. Mr. Liu had bought a car for one year. Although he cared for car care, he still knew nothing about the vehicle. When his car was about 7,500 kilometers in length, he was asked to change the filter, spark plug, and cleaned the engine. He spent more than 900 yuan. Xiao Wu, a friend who understands car maintenance, told him that he was fooled.
Like Mr. Liu's car to do 7,500 kilometers of maintenance, plus material costs, working hours and costs up and down 300 yuan, but the repair shop flickered to replace a large number of items that do not need to be replaced, and do unnecessary maintenance. Automotive oil, brake oil, spark plugs and other accessories need to be replaced on a regular basis, but each accessory and oil has its service life. If we understand the lifespan of some auto parts and oil products that are most likely to be fooled, we can guard against it when doing car care.
　 Mo hurry to change: "three filter" replacement deadline
Xiao Wu introduced that every time the car is regularly maintained, the oil filter must be replaced. The long-term driving in non-dust areas, air filters can generally use 20,000 kilometers, 7500 kilometers only need to do some cleaning. The life of gasoline filters is related to the use of oil products. If you have been fueling at a regular gas station and you have not experienced poor oil supply, you may consider replacing them over 20,000 kilometers.
In addition, under normal use, the brake pads can use 30,000-40,000 kilometer, and the original battery can use 3-4 years. Spark plugs are more categorized, ordinary nickel alloy spark plugs can be used 20,000 -3 million kilometers, platinum spark plugs can use 80,000 -10 million kilometers, gilded spark plugs can use 30,000 -4 million kilometers and so on. The owner can properly adjust the service life of these components and oil products according to the maintenance manual of his own vehicle and the actual condition of the vehicle.
Do not listen to Huyou: oil replacement deadline identification
Oil replacement is a "professional" recommendation that repair shops do more when doing car care. Oil products should not be replaced, not only to listen to their opinions, but also to have their own understanding of their own hearts.
Brake Fluid: Manufacturers generally require replacement of 50,000 kilometers or so, but there is not much problem in the actual situation, and brakes do not have to be replaced without exception. Brake oil is almost out of hand brake light will be bright or flashing, this time changing the brake oil is not too late, do not change the maintenance plant to change.
Engine oil: The foreign engine oils are basically changed to 10,000 kilometers before being replaced. Domestic manufacturers generally advance the replacement cycle to 7,500 kilometers with poor domestic road conditions, and now reach 5,000 kilometers in advance. However, as long as the oil is clear and the oil level is not lower than the minimum indicated level, the replacement of the oil is not so frequent without special circumstances.
Steering booster oil: Steer booster oils do not need to be changed frequently. Dealers also recommend that 100,000 kilometers be exchanged once, without replacement, there will not be any safety hazards. If the lack of steering assistance oil will cause abnormal engine noise, the steering assist oil also has the lowest mark and is replaced below the minimum mark.
Do not want to wash and wash: more than 30,000 kilometers before washing
The so-called deep engine cleaning is actually cleaning the engine's internal lubrication system and carbon deposits. Xiao Wu said that due to the long-term operation of the engine under high temperature and high pressure conditions, the resulting sludge and carbon deposits will reduce engine operating efficiency, which is necessary for old cars of a certain age.
However, most of the lubricants used in cars today have their own cleaning function, which can ensure that the engine does not produce sludge or the quantity is small in a certain number of kilometers.
The deep cleaning of the engine when the new car is in Second Life will cause huge waste and is completely unnecessary.
The repair shop guys saw Mr. Liu's eagerness in the car and only casually recommended him to these packages.
Xiao Wu introduced that cleaning lubrication system, intake port, combustion chamber and other items are necessary to maintain the car's engine, but in the normal state of use of the vehicle, generally 30,000-50,000 kilometer will be considered.
Mokianjia added: new cars do not add additives
As the number of motor vehicles continues to climb, a large number of businesses are also targeting the oversized cake in the automotive supplies market. However, the quality of its products is also mixed, or it is purely a concept of flicker. There are numerous products such as various anti-wear agents, cleaning agents and restoratives. Some auto repair companies are eager to sell various kinds of additives to vehicle owners in order to maximize profits. Maintenance experts said that regular manufacturers of anti-wear agents and repair agents have a certain repairing effect on some vehicles that have been worn out. Adding unqualified additives may cause changes in the properties of lubricating oil, resulting in reduced efficiency of lubrication systems and deterioration of oil products. Increase mechanical wear. For a new car, it is best not to add anything without understanding the performance of the product.
In addition, a large number of anti-cleaning agents for electronic throttles, injectors, inlets and other components are of limited effectiveness. It is better to go to regular workshops to take apart and wash them regularly.
