How to maintain the car?

Before talking about how to maintain, let's talk about why the vehicle needs to change the oil filter regularly for maintenance. There are three main reasons;

The garbage needs cleaning.

As we all know, the engine of a car is made up of many parts. In order to output power, there are many parts in it, which keep moving when the car is driving. Friction between metals will produce a large number of metal fragments.

In addition, automobile internal combustion will also produce a large number of particulate matter such as smoke and dust.

Coupled with the inhalation of a large number of dust particles in the intake air, these substances will increase with the increase of vehicle mileage, which is what we usually call sludge.

The increase of these substances will aggravate the wear between friction pairs. If the clean oil cannot be replaced in time, the wear will become more and more serious. Over time, the noise of the vehicle will become louder and louder, and the fuel consumption will also increase.

Oil itself can't carry it.

In the process of engine combustion, some gasoline will not be completely burned, and the water produced by combustion will enter the engine oil.

At the same time, part of the combustion waste gas enters the engine oil, which will gradually lead to the aging and deterioration of the engine oil.

In the early stage, the viscosity of engine oil will decrease and the lubrication effect will become worse. In the later period, the engine oil will even deteriorate and gradually lose its lubricating function, resulting in dry grinding of friction pairs and vicious accidents such as Lavalas cylinder pulling.

Filter leakage

Mechanical filtration can play a filtering role because the filter paper inside can filter out large particles and provide clean engine oil that can meet the lubrication needs.

However, if it is not replaced for a long time, the filter paper will be blocked by a large number of impurities and lose its filtering ability, so that impurities will cross the machine filter and enter the engine, resulting in engine damage.

To sum up, it is necessary to change the oil filter regularly, and the money cannot be saved. Let's talk about how to maintain it reasonably and scientifically.

The most important thing in auto insurance is the first insurance. Generally, the first coverage is 3000 kilometers or three months. The first insurance must be early rather than late. Why do you say that?

1, the actual work needs of the engine;

Because the internal parts of the new car engine are brand-new parts, there may be some micron-level machining protrusions on the surface of the parts, some surfaces may have high points of scratches, and even some parts may have bad flash burrs.

At this time, in the early driving process, with the running-in of new cars, a lot of wear debris will be produced. Under normal circumstances, these debris will be deposited in the oil in the oil pan and the mechanical filter. The engine may be damaged if it cannot be replaced as soon as possible.

2. Business requirements;

Because the first insurance is very important for vehicles, each manufacturer has clear first insurance regulations for each product.

If the first insurance is not done in time and the vehicle is damaged, the merchant can refuse to pay compensation, which will cause great losses to us, so the first insurance must be done in time.

Here, "catch up with the morning and not catch up with the night" does not mean that you have to run maintenance after running for five or six hundred kilometers. Generally, it is an ideal mileage to run 2500-2800 kilometers, because at this time, the vehicles are fully running in and the worn debris is cleaned up in time. At the same time, it will not be produced in a short time after replacement, killing two birds with one stone.

3. Give it away for free and enjoy it in time;

Generally, some maintenance will be given when buying a new car. You must do maintenance in strict accordance with the regulations in the store and know how to enjoy it in time.

If you really use a car in other places, you can't maintain it in time, but you must not maintain too many miles.

Because the over-insurance mileage is too long, it is not good for the vehicle and may cause damage to the vehicle. In addition, the store can completely refuse to repair on the grounds of over-warranty, so we will lose more than we gain.

How to maintain it during the warranty period?

Every car has a clear maintenance mileage, which is determined by the car company according to the test to ensure that the car will not go wrong. This mileage will generally ensure that there will be no problems with the car, and will also consider the interests of dealers, so this mileage must be a relatively conservative mileage.

For example, the inspection can be replaced by 65,438+00,000 kilometers, but the mileage set by after-sales maintenance may only be 5,000 kilometers, which is a margin.

As a research and development personnel, I can only say here that the mileage you see in the maintenance manual is definitely discounted. As for how much? The situation of each car, using different oil products, can not give a unified figure.

For the vehicles within the warranty period, don't worry about the deposit first, and try to maintain them as required. Don't exceed too much mileage, generally within 500Km, there should be no problem, but if it exceeds too much, the manufacturer can refuse to pay compensation, which will cause us great losses.

As for what oil to use during the warranty period, don't be fooled by the younger brothers and sisters in the 4S shop, just use the designated special engine oil developed by the cheapest manufacturer.

The so-called high-end engine oil you blow in the shop can't be said to have no effect at all, because most of these oils are added with some anti-wear agents.

Reducing wear and tear will make some contribution to more fuel consumption, but I can tell you clearly that the extra money you spend far exceeds the little oil money you save, which is not worth the candle.

As for why I recommend it to you in the store, I can think of it with my feet, of course, in order to make more money.

After the warranty period, my car owner is responsible.

For vehicles that have exceeded the warranty period, we can choose the most cost-effective way to maintain our cars without being restricted by manufacturers.

As mentioned above, the maintenance mileage stipulated by the manufacturer is discounted, so after the warranty period, we can let go of this discount and reduce our maintenance cost. As for how long it can be extended, it depends on the kind of oil you use.

For example, you use synthetic engine oil for maintenance, and the mileage of 10,000 kilometers is not a big problem. Don't listen to the 4S shop and change it to 5,000 kilometers. It's totally a gift.

However, if you use a semi-synthetic engine oil and the recommended maintenance mileage in the store is 5000 km, then we usually drive to 7000-8000Km, which is generally no problem, so it is not recommended.

The above suggestions are aimed at the relatively good road conditions of people's daily cars. Usually, people use cars on the sidewalk. If your car is in a mining area, Gobi desert and other areas with heavy wind and sand, then this recommended mileage is problematic. Everyone should try to maintain according to the mileage recommended by the manufacturer to avoid vehicle damage.
