Is it necessary to maintain the car on time?

Is it necessary to maintain the car on time?

Just because the car doesn't run often doesn't mean it can be maintained. It's like buying a villa and never opening the door at ordinary times. The grass in the yard has grown tall and needs to be taken care of. The reason is the same. Even if you don't use these things, you still have to pay the property fee, right? That's the truth.

1. What should I pay attention to during the maintenance period?

(1) Do something normally if you don't open it often.

The first is the various oils in the car, such as engine oil, brake oil, antifreeze, gearbox oil, steering power oil and so on. Even if they don't open, they will slowly oxidize and deteriorate if they are left there. Buy a bucket of vegetable oil and pour it into a bowl. If you leave it there like this, it will be broken for months, right? Oil, even if the car 1 year is only 2000km, it is best to change it regularly according to the maintenance manual.

Wang Zhikuan of Liaocheng University has a master's thesis "Study on the Quality Deterioration and Prediction Model of Passenger Car Oil", in which it is said that the main forms of engine oil quality deterioration are oxidation deterioration and pollution deterioration, and the antioxidants in engine oil additives will gradually degrade and fail over time. And brake oil. Gao published a paper in the journal "Internal Combustion Engine and Accessories" and "Research on Daily Use and Maintenance of Automobile Brake Fluid", which mentioned. Ethylene glycol, a component of brake fluid, has a strong "hydrophilicity" and will constantly absorb moisture in the air.

Some friends drive less, but the parking environment is humid, so they rarely see zero-humidity parking lots, right? Brake oil will continue to absorb water and deteriorate. If the water content or "water content" exceeds 4%, it should be replaced. Therefore, even if it is rarely opened, it needs to be checked and replaced regularly according to the maintenance manual.

There are also some rubber parts, such as tires and wipers. Even if you rarely drive, you have to work 1 day every 1 week, that is, 4 times every 1 month. These rubber parts are still naturally aging, and they need to be replaced after a certain period of time. The National Highway Traffic Safety Administration (NHTSA) of the United States has a suggestion: tires that are more than 6 years old should be considered for replacement; Tires that are more than 10 years old can no longer be used. Even though the car has only driven 65,438 438+ 10/00000 km in six years, the tread pattern is deep and looks like new, because the structure inside may be aging. Do you have that kind of cowhide tendon that has been used at home for a long time? Take it out and pull it a little, and it breaks, a bit like this. Some friends may think: "I drive 1, 1 2000km a year, which is also maintained according to normal time." It's really uneconomical and unnecessary, isn't it? " "Can I extend the maintenance period a little?

For example, more than 2 months or 3 months should not be a problem, right? The car should not explode, right? "This thing is a bit like the shelf life of food. The shelf life of potato chips is 1 year. It doesn't mean that 1 year 0 1 second will go bad immediately, and mushrooms will go bad immediately. Will you have diarrhea after eating them? 1 year, 1 year, 1 month for a few days, you may still be able to eat, but the risk will be particularly high or the taste will become particularly strange. So this thing is really not so absolute, but it should be noted that if the car is still under warranty, you need to have a good chat with the 4S shop in advance. Generally speaking, in order to protect customers, 4S stores also allow this, but only need to leave his written records or recordings.

(2) What things don't open often will really be left out.

Besides the on-time maintenance items mentioned above, there are indeed some maintenance items. If you drive less, you really don't have to strictly follow the rules. For example: for example, brake pads, the car doesn't work very well, and the brake pads are worn out and need to be replaced. We didn't grind them, did we? The material of the brake pad itself is not rubber, which will not age slowly and will not be very slow. We need to drive this thing less, so we can change it less. Li Zhonghe Chen Mengqing published a paper "Research Status and Development Trend of Brake Pad Friction Materials" in the magazine "Aging and Application of Synthetic Materials", and talked about this point. The components of brake pads are basically inorganic substances such as ceramic fiber, metal fiber, lead, copper, zinc, feldspar powder and graphite, which are similar to natural stones, and will not change much after 5 years or 10 years.

Forget the pyramids of Egypt. They have been blown like that for hundreds and thousands of years. There is also a spark plug, which is usually opened less and can be replaced when there is no time. Whether the spark plug needs to be replaced is judged by the electrode gap. The normal electrode gap is 0.6 to1.3 mm. If it exceeds this range, it may need to be replaced. According to the data of Denso official website, the electrode wear of spark plug is about 0.10/5 mm per 1000 km. If you don't open it too much, the spark plug electrode will wear less, and the problem of replacing it in the future will not be so big. Of course, it is necessary to take it out and check it regularly.

2. What should I pay attention to when parking?

In addition to paying attention to the maintenance cycle, there are actually many details worthy of attention when parking the car. As I said before, if possible, even if you don't drive, 1 it's best to take a walk in two weeks. Just like people. We have to go out for a walk once in a while, climb mountains and stretch our muscles, right? Otherwise people will get sick. If you have something to do, you will have to travel for half a year, or even go abroad for a year. Before the car is parked for a long time, it is recommended to clean the body and interior, put on the car coat, cut off the battery and raise the tire pressure appropriately.

If there is still oil in the tank, you should pay attention to it yourself: if ethanol gasoline is added, it will deteriorate for a long time. It's best to run away in advance or just leave a little, and then add some regular gasoline to the tank.

Now, in many areas, No.92 gasoline is ethanol, but No.95 gasoline is not. You can consider adding 95, where it is safer. In this way, even if you come back to drive after half a year, you won't have all kinds of strange problems in various places as soon as you get on the road. Of course, don't forget to reconnect the power, even if you have friends.

3. Replace according to the maintenance manual.

So in general, if you buy a car but don't drive it often, it is best to follow the maintenance manual for items such as oil and rubber parts. However, spark plugs and brake pads should be replaced according to actual consumption or wear. Just check them.

4. Why is the car "not afraid to use, but afraid to let it go"

In fact, there are not so few friends who don't drive often when buying a car, or who are called "not driving very much". But there is no such dialect on the Internet. "The car is not afraid to drive, and they are afraid to put. If you stop, you will age faster. " Is this sentence reasonable? Suppose 1 year car can't run at all, what will happen? This car hasn't moved at all. What else do you need to pay?
