How often should the fuel filter be replaced?

Fuel filter is also called fuel grid or petrol grid. It can filter impurities in gasoline to reduce the formation of dirt in the combustion chamber of the engine, and its clean purity can be effectively guaranteed.

If the fuel filter is too dirty or clogged, it is mainly manifested as: when the gas is added, the power is slow or cannot get up, the car is difficult to start, sometimes it takes 2-5 times to hit the fire. Most engines are equipped with disposable non-removable paper-based gasoline filters. The replacement cycle is generally 10,000 kilometers. If you add gasoline with less impurities, it is not a problem to replace one at 15,000-20000 kilometers. The filter is marked with arrows on the inlet and outlet ports. Do not install it backwards when replacing it.

The material of the fuel filter varies from car to car. The price of fuel filter for most economic models is between 50 and 100 yuan, and the price of fuel filter for a few special models is between 100 and 200 yuan. The gasoline price of mid-to-high-end cars is above 100 yuan, and the overall difference is not much. Some sub-factory parts or miscellaneous brand gasoline grids are likely to cause oil leakage, may cause spontaneous combustion or even explosion, and are quite dangerous to the body and the human body.
