The gasoline filter is the same as the diesel filter:
1. Diesel filter element is a kind of gasoline filter element. Diesel filter element is mostly made of filter paper, and some use felt or polymer material. Gasoline filter element is mostly made of filter paper, and some use nylon cloth and polymer material;
2. Due to the different combustion methods of gasoline engines and diesel engines, the overall requirements of gasoline filter elements are not as harsh as those of diesel filter elements, so the price is cheap;
3. The pore size of the filter is different, and the material it selectively filters is different. The diesel filter mainly filters suspended solids and particulate matter. Due to the low viscosity and good fluidity of diesel oil, the filter pore size is small;
4. The oil filter is mainly used to filter the colloidal substances in the working oil and the debris generated by mechanical wear. Due to the high viscosity of the oil, the pore size of the filter element is also large.

If the gasoline filter is not changed for 20,000 kilometers, the life of the car engine will be damaged, and the fuel injector will be damaged, the cylinder will be worn out, and the power will decrease:
1. Gasoline filter is referred to as steam filter. Gasoline filters are divided into carburetor type and EFI type. For gasoline engines using carburetors, the gasoline filter is located on the inlet side of the fuel pump, and the working pressure is low. Generally, nylon shells are used. The gasoline filter is located on the outlet side of the fuel transfer pump, and the working pressure is relatively high, usually with a metal casing;
2. The filter element of the gasoline filter mostly uses filter paper, and there are also gasoline filters that use nylon cloth and polymer materials. The main function is to filter out impurities in gasoline;
3. If the gasoline filter is too dirty or clogged. Line filter paper gasoline filter: The gasoline filter is inside this type of gasoline filter, and the folded filter paper is connected to both ends of the plastic or metal filter. After the dirty oil enters, the outer wall of the filter is filtered by layers of filter paper. Arriving at the center, clean fuel flows out.
