What is Fuel Filter?

Şampiyon Fuel Filters Extend The Life Of Your Engine!
June 27, 2022

The fuel must be filtered very well in order to avoid any clogging and damage in the fuel system. Poor filtration causes problems such as decreased engine performance, increased fuel consumption, malfunctions in engine operation and shortened engine life. Fuel filters clean the fuel from particles that are very dangerous for fuel systems and engines. For this reason, it is among the inseparable and indispensable parts of vehicles. The fuel filter collects dirt, dust and debris before it enters the fuel system. Thus, any particles that may be in the fuel do not reach the engine by staying in the filter. This helps to extend the life of the engine and prevent damage. For these reasons, fuel filters are among the most important and necessary components of maintaining engine health.

What Does a Fuel Filter Do?

Particulate matter in fuel causes wear on different engine parts due to its abrasive nature. Fuel pump, carburetor and injection system are very sensitive to foreign particles in the fuel. The filters installed in the fuel system of the automobiles should be such as to increase the efficiency of the engine and extend the life of the engine parts. The function of these filters is to prevent the abrasions that may occur in the engine by cleaning the solid particles as well as water, paraffin and organic matter impurities (bacteria that live in water and mix with the fuel) from the fuel before they reach the engine. Choosing the right filter, servicing the filter, and replacing the filter when required will help significantly increase the life of the engine.

How Often Is The Fuel Filter Replaced?

In order to increase the performance of the vehicle and the vehicle engine, it is necessary to replace the fuel filter regularly. If a filter is not replaced regularly, it can become clogged with pollutants and cause a restriction in fuel flow, resulting in a significant decrease in engine performance as the engine tries to draw in enough fuel to continue operating normally.

Filter chambers in vehicles show dimensional and positional differences according to manufacturer designs. Due to these differences, fuel filter usage times vary from vehicle to vehicle. The replacement frequency determined by the manufacturer should be taken into account. In addition, how often the fuel filter is replaced depends on several factors, including how clean the fuel is, the type of fuel, and whether it is a primary or secondary filter. It also depends on the driving habits.

Driving with a low fuel level frequently shortens the life of the fuel filter. Sediments are usually collected at the bottom of the fuel tank and driving your vehicle with a low fuel level causes these impurities to reach the fuel filter and clog the filter as a result. It is very important to replace the filter at the right frequency in order to prevent impurities in the fuel from reaching the engine. Otherwise, when the filter becomes worn out, it cannot do its job and may cause the particles in the fuel to escape into the engine.

How Is a Fuel Filter Chosen?

When choosing a fuel filter, you must first choose according to the model of the vehicle and engine. Although these filters work similarly, fuel filter models may differ according to the vehicle make and vehicle model. For this reason, you need to choose the most suitable filter for your vehicle model and make.

In the filter search section of our website, there is a search by vehicle section, and by typing your vehicle information in this section, you can access the correct filter codes you need to use.

Alternatively, by searching the code of the different make on your vehicle in the "Search by Code" section, you can access the filter code at the appropriate pass for your vehicle in our company.

Other issues to consider when choosing a filter;

Pore Size and Efficiency

Fuel filters have different pore sizes. A lower pore size means the filter captures smaller pollutants more efficiently and provides better protection to the engine. However, such filters have a shorter lifespan. Although such filters are efficient compared to filters with large pore diameters, they can become clogged and strain the fuel pump in a shorter time.

Type of Filter Media

Fuel filter media generally comes in two main types: natural and synthetic. Cellulose falls into the natural category made from plant fiber. Cellulose is often preferred because it minimally restricts fuel flow. It doesn't strain the fuel pump, which makes the pump last longer. Synthetic fuel filter media is mostly glass fiber. This type of media filters finer particles and provides better engine protection. However, this also results in a shorter filter life.

What Are the Symptoms of an End-of-Life Fuel Filter?

These signs that you need to replace your fuel filter are usually caused by a dirty fuel tank, a damaged filter, or a clogged fuel line.

  • In the worst case, the engine does not start at all. The fuel cannot pass through the clogged filter as there are unwanted particles such as dirt, dust and residue in the fuel.
  • Engine runs roughly at idle – the level of clogging of the filter causes the vehicle to not operate properly, especially at low speeds.
  • The vehicle has difficulty accelerating. You experience a lack of power, especially when overtaking, driving uphill or carrying heavy loads, due to the fuel system's inability to inject enough fuel into the engine.
  • Even if it runs smoothly at startup, the engine may stall frequently.
  • Engine fault light may come on. This warning comes on when the pressure sensor detects a lack of fuel pressure.
  • The performance of your vehicle decreases. Therefore, fuel economy is reduced.
  • Your car may emit more exhaust fumes than normal. A clogged fuel filter can cause the engine to emit more fumes.
  • Your injection system, especially the carburetor and injector nozzles, may oxidize (corrode). Since the fuel system is difficult to access, it can be difficult to detect this outside of the auto service.

Şampiyon Filtre was established in 1985 as a small family business, the foundation of which was laid in Iskenderun. Our company, which took its name "Şampiyon" from the goal of "Success in Filtering" that has been its main principle since the first day of its establishment, has transformed into a larger family with more than 35 years of experience and continues to produce high quality oil, fuel, air and hydraulic filters for automotive, agricultural machinery, construction machinery, commercial bus and truck groups in accordance with national and international standards.*
