All car owners know that cars need maintenance, but they may not be clear about what specific maintenance is needed. While they know that they need to do an oil change every year and replace air and AC filters, they may overlook the existence of the fuel filter element.
In the following paragraphs, I will explain what happens when you don't replace the fuel filter element.
The main function of the fuel filter is to filter out impurities mixed with gasoline, protecting parts such as the oil pump nozzle, cylinder liner, and piston rings, reducing mechanical wear, preventing fuel system blockage, ensuring stable engine operation, and improving vehicle safety.
Classified by car type
Gasoline filters: Gasoline filters are used in gasoline vehicles and are divided into two types: carburetor and EFI (Electronic Fuel Injection) filters. Carburetor filters use nylon shells, while EFI filters use metal shells.
Diesel filters: Diesel filters are used in diesel vehicles and are divided into replaceable and spin-on types. Since diesel engines are extremely afraid of water in the fuel supply system, the filtering effect of diesel filters must be good.
Classified by installation method
External fuel filter element: Most cars use external filters, which are easier to replace.
Internal fuel filter element: The filter is located inside the fuel tank, which is not only complex to replace, but also more expensive than external filters.
The Consequences of Not Replacing the Fuel Filter element for a Long Time
Decreased power: If you don't replace the fuel filter element for a long time, impurities may clog the fuel injection nozzle, reducing the passability of gasoline and affecting the timely supply of fuel, causing a decrease in power. This will affect your driving experience and make it difficult to overtake others on the road.
Increased fuel consumption: If the fuel filter element is not replaced, the fuel system will not be smooth, the oil pressure will be insufficient, and the fuel consumption will increase, which is a common concern among car owners.
Increased carbon deposits: If the filtering effect of the fuel filter element is not good, impurities in gasoline will flow into the cylinder, and incomplete combustion of gasoline will result in increased carbon deposits. Cleaning carbon deposits can be expensive and will further affect the engine's performance.
Difficult start: When the fuel filter is severely clogged, starting the car may be difficult or even impossible. It can take several attempts to start the car, and this can be very frustrating in emergencies.
To ensure the normal operation of the filter, it is recommended to replace it according to the maintenance manual, which is every 30,000 kilometers under normal driving conditions. Or, you can replace the fuel filter element according to your actual driving conditions.
The fuel filter element is used to filter impurities in gasoline, so it is important to be careful when refueling. Make sure to refuel at a regular gas station because poor quality gasoline can directly affect the service life of the fuel filter.
