Excessive use of oil filter results in increased fuel consumption, weak start, and significantly reduced power. The filter paper inside the oil filter is completely black and has lost its filtering effect. Therefore, the long-term mixed combustion of deteriorating oil and gasoline has a great impact on the engine. Of course, in addition to replacing the oil filter, the inspection and replacement of the air filter and the gasoline filter are equally important. I would like to remind everyone that the "three filters" must be replaced in time, otherwise the life of the car will be shortened by ten years!

Gasoline Filter

　　Before talking about the gasoline filter, let me talk about the quality of gasoline. Iraq’s oil fields are very well-known. At the same time, the crude oil is relatively high-quality. The wax content of Iraqi crude oil that can be measured at -30 degrees Celsius is 0.9%. That is to say, the lower the gasoline wax content, it means that it contains fewer long carbon chain components. The more long carbon chain components contained in gasoline, the less sufficient combustion is and the easier carbon deposits inside the engine. The wax content of crude oil in my country is about 15% to 20%. That is to say, a good gasoline filter is very important in the harsher environment of domestic vehicles.

　　Gasoline filter, most people know its role is to filter impurities in gasoline. Because modern cars use electronic fuel injection, the oil pressure is relatively high, so the gasoline filter shell is now wrapped, and the internal material is made of filter paper. The higher-end gasoline filter is made of nylon or polymer materials.

Air Filter

　　Clean gasoline needs to be mixed and burned with pure air to maximize fuel economy. Generally, the air filter replacement cycle is 10,000 to 15,000 kilometers. If the replacement range is exceeded, the air filter will lose impurities from the filtered air entering the engine. In this way, the protection of the engine's internal pistons, intake and exhaust valves, piston rings, and cylinders will be lost. Imagine exaggeratedly, what happens when the engine is at 3000 rpm and the cylinder contains some small sand and rubs together?

　　Of course, things are not so simple. After the maintenance period has not been replaced, the air filter is not replaced because of the poor filtering effect and difficulty in inhaling, resulting in insufficient mixing of gasoline and air, which is prone to carbon deposits and decreased power. In the long run, fuel consumption will increase significantly, and the cost of using 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 damage the engine and shorten the life span and bring a series of maintenance costs, but it is very troublesome.

Oil Filter

　　It is necessary to change the oil every time you go for maintenance. Engine oil can play a role in sealing, lubricating, cooling, and decontamination inside the engine. The most important thing is lubrication.

　   Most of the oil filters use paper filters, mainly to filter the oxides and other impurities generated by the engine during operation. When the oxides and impurities adhere to the oil, then the oil filter is required. After the oil filter filters a large amount of impurities, the filter material blocks the filter paper. At this time, the filtering effect has been greatly weakened and needs to be replaced, whether it will affect the engine.

　　If only the oil filter is replaced without changing the oil, it will also have no effect, because the cleaning function of the oil is very important in addition to lubrication. After the oil filter is "contaminated", the filtered oil is also contaminated, carrying impurities to lubricate, and it is difficult for the engine to not be damaged. From the blackened oil filter, we can see that the oil has deteriorated. The deteriorated oil has poor fluidity and high viscosity, which hinders the work of the engine piston. In addition, if the resistance is large, the oil flow will be less and the lubrication effect will be compromised. 

　　If long-term hybrid (deteriorated 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 Conditioning Filter

　　In the spring, many people have a cold and fever. These reasons are generally considered to be unsuitable for the body during the changing season, but have you ever thought that it is caused by the air conditioner filter? The air-conditioning filter has not been used for a winter, and the bacteria attached to the air-conditioning filter have grown for a long time. After using the air conditioner in the spring, the air conditioner directly blows bacteria to the passengers in the car. The entire car is a place full of bacteria. This is how a cold and fever come.

　　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 is full of impurities, the air-conditioning filter loses its filtering effect. If the air conditioner is turned on at this time, the impurities attached to the air conditioner filter will not be blown into the car. Whether it is bacteria or dust, I think the passengers in the car will be uncomfortable.

　　Through the three filters, in the case of expired but not maintained, you can see the problem intuitively. A seemingly simple accessory, for owners who do not maintain the car on time, only saves a few dollars, but in fact the impact is not as simple as money.
