Have you ever thought about shortening the life of your beloved car because it is not replaced in time? Have you ever thought about catching a cold because you don't change the air conditioner filter on time? Have you ever thought about not replacing the three filters in time and paying the price? Come, let's understand the maintenance and car maintenance talk about how much damage is not timely replacement of three filters.
 
● Gasoline filter
Before talking about the gasoline filter, I want to say something about the quality of gasoline. Iraq oil field is very famous, and the crude oil is relatively high quality, Iraqi crude oil through the temperature of -30 degrees Celsius can be measured by the crude oil wax content of 0.9%, that is to say, the lower the wax content of gasoline, it means that it contains less long carbon chain components, gasoline contains more long carbon chain components, it is not so full, the engine is more likely to deposit carbon; The crude oil wax content in our country is about 15% to 20%, that is to say, the vehicle environment in the country is more severe, and a good gasoline filter is very important.
Gasoline filter, most people know that its role is to filter impurities in gasoline. Because modern cars use electric injection fuel supply, the oil pressure is larger, so now the gasoline filter shell is wrapped, and the internal material is composed of filter paper, and the higher-end gasoline filter has nylon material or polymer material.

● Air filter
Clean gasoline needs to be mixed with pure air for maximum fuel economy. We can see the comparison of the appearance of the air filter below, which is very obvious. Generally, the cycle of replacing the air filter is 10,000 to 15,000 kilometers, and if the air filter exceeds the replacement range, it will lose the impurities that filter the air into the engine, so that the protection of the internal piston, the intake and exhaust valve, the piston ring, and the cylinder will lose its function. When the engine is at 3000 RPM, the cylinder contains some small sand and friction together, but what is the situation?

Of course, things are not so simple, after the maintenance period has not replaced the air filter, because the filtration effect is poor, breathing difficulties lead to insufficient mixing of gasoline and air, easy to produce carbon deposition and power decline; In the long run, fuel consumption increases significantly, and the cost of the car will increase a lot. Therefore, it is very important to replace the air filter according to the normal maintenance cycle, otherwise it will hurt the engine and shorten the life and bring a series of maintenance costs.
 
● Oil filter
Every time you go to maintenance and change the oil item is a must. The following model uses semi-synthetic oil, according to the maintenance cycle regulations to replace the oil kilometers of 7500 kilometers, but this guy in 7800 kilometers to replace the oil, when the oil is put in, we can obviously see the yellow oil after 7800 kilometers what color? Oil in the engine can play a sealing, lubrication, cooling, decontamination and other functions, the most critical of which is lubrication, but the oil shown in the picture can also have lubrication function?
Let's take a look inside the oil filter. Most of the oil filters use paper filters, mainly to filter the oxides and other impurities produced by the engine in the work, when the oxides and impurities are attached to the oil, then the oil filter is needed to filter. After the oil filter filters a large number of impurities, the filter blocks the filter paper, and the filtration effect has been greatly weakened, and it needs to be replaced, whether it will affect the engine.

If we only replace the oil filter without replacing the oil, it is also without any effect, because the oil in addition to lubrication cleaning function is very important, oil filtration is "polluted", through the filter oil is also polluted, with impurities to lubricated, the engine is not bad.
By comparing the old and new oil filters, we clearly see the difference between the new oil filter and the new oil filter after 7800 kilometers. From the blackened oil filter, we can see that the oil has deteriorated, the deteriorated oil has poor fluidity, large viscosity, hindering the engine piston work, in addition, if the resistance is large, the oil flow will be less, the lubrication effect will be reduced.

If long-term hybrid (stale oil plus gasoline) combustion is bound to affect the engine. The problem can be effectively solved by replacing the oil filter, and the price of replacing the oil filter is not expensive.

● Air conditioner filter
In the spring period, many people have a cold and fever, and these reasons are generally considered to be unsuitable for the body during the conversion season, but have you thought about it because of the air conditioning filter? The air conditioning filter is not used after a winter, the bacteria attached to the air conditioning filter after a long time to breed, and then through the use of air conditioning in spring, the air conditioning directly blows the bacteria to the passengers in the car, the whole car is a place full of bacteria, and the cold and fever is like this.

The main function of the air conditioner filter is to filter the air impurities in the car, but the air conditioner filter has a certain replacement cycle. When the air conditioning filter adsorbed impurities has been full, the air conditioning filter will lose the filtering effect. If you turn on the air conditioner at this time, the impurities attached to the air conditioner filter will not blow into the car, whether it is bacteria or dust, I think the passengers in the car are not happy.

Through the three filters in the case of expired maintenance, we can intuitively see the problem. Seemingly a very simple accessory, for not maintaining the owner on time, just save a few money, but in fact the impact is not so simple money.
