How often should I change my fuel filter? Does the built-in fuel filter need to be replaced?
Many people think that the fuel filter is not too important and will not be dirty, so the maintenance is recommended to change the fuel filter are not changed. In fact, this is not correct, it is the same as the oil filter and air filter, it must be replaced regularly, which is the most basic maintenance project to ensure the life of the engine, and it is not possible to save money and not do this project. If the external fuel filter,
Many people think that the fuel filter is not too important and will not be dirty, so the maintenance is recommended to change the fuel filter are not changed. In fact, this is not correct, it is the same as the oil filter and air filter, it must be replaced regularly, which is the most basic maintenance project to ensure the life of the engine, and it is not possible to save money and not do this project. If the external fuel filter, its price is not high, most of the ordinary vehicles tens of dollars to hundreds of dollars can be dealt with.
Petrol filter is divided into external and built-in two kinds, most of the cars are external, the shell is iron, inside is made of filter paper, and the oil filter is very similar to the internal, the filter paper plays the role of filtering impurities. Replacement is also very simple, and the connection of the oil pipe is a card, pinch and pull out and insert. The replacement cycle of the petrol filter is 10,000 kilometres for some cars and 20,000 kilometres for others, of which 10,000 kilometres for a car more, you can consult the maintenance manual of the car. Do not think that petrol is very clean and does not have too many impurities, the cartridge will not be dirty even after tens of thousands of kilometres. This is not true, generally 10,000 kilometres of the cartridge is really not too dirty. If it is to 15,000 kilometres or 20,000 kilometres replacement, the cartridge removed and then pour out the petrol inside the view, you will see that the petrol has been very black, which means that the inside of the filter paper is also very black, there is a lot of sludge on it.
A lot of sludge on the filter, first of all, the filtering effect will be worse, there will be a lot of impurities through the filter to the cylinder, easy to accelerate the production of carbon deposits in the cylinder. If there are large particles of impurities, there is a possibility of clogging the injectors. In addition, the passage of petrol is not good, the oil circuit is not smooth, resulting in insufficient oil pressure, which in turn leads to incomplete combustion, the car's performance to reduce fuel consumption increased carbon deposits increased. Some people say that they drive and do not feel abnormal, because the changes in the car's condition is gradually to become, they drive every day is not easy to notice, after the maintenance will obviously feel that the car is good to drive, become lighter and faster, the performance is improved.
There are also a small number of cars that have a built-in fuel filter, which is installed in the fuel pump, positioned in the fuel tank, always immersed in petrol. This type of filter has a long life and you don't need to think about changing it until around 100,000 kilometres. If the car is driven sparingly, it will only need to be changed once after many years. However, changing this filter is a bit of a hassle as you have to remove the fuel pump to change it and the labour costs are relatively high.
Filter dirty fast and slow also has a lot to do with their own oil, regular petrol station oil qualified, relatively few impurities, filter dirty slow. If you fill up with unqualified oil at a small service station, there will be relatively more contaminants and the filter element will become dirty more quickly. Regardless of where you fill up, the filter element should be changed on time, and when it comes to the change cycle, it should be changed directly without delay. And replace the filter element should be of good quality, if you buy a very cheap filter element, there may be poor filtration effect after a long time, and even the filter paper inside the filter element will be rotten, there is a risk of clogging the injector nozzle.
