Buyer's Guide

One of the main criteria for selecting a filter is the degree of purification. In the technical documentation, its value is indicated in percent. The value refers to the amount of contaminants that the filter is able to contain.

It can be identified by markings:

  • "medium " retains no more than 60% of solids,
  • "nominal" - up to 90%,
  • "absolute" - 99.99%.

The fineness of screening reflects the ability of the material to retain particles of a specified size. According to this indicator, filters are divided into several categories: coarse, normal, fine purification. The recommended value depends on the type of the car engine. For gasoline engines, the fineness of sifting should be about 5 micrometers, for diesel engines - about 10 micrometers.

Attention should be paid to the quality of the filtering material. Usually it is made of paper. It must not delaminate and lose its fibers when exposed to mechanical impact or getting wet.

Even barely noticeable separation of lint will intensify in the process of operation and lead to regular contamination of the fuel system of the car.

An important criterion is the density of the winding. Due to insufficient filter material, large particles of contaminants will enter the system. If it is impossible to visually inspect the filter hidden under the deaf housing, it is worth considering the weight. The optimum weight of the cleaner is 200 grams or more.

The manufacturers recommend installing a new fuel filter every 25 thousand kilometers or twice a year.

Quality of the fuel filter

Even well-known developers are capable of producing defective products that somehow were not noticed in the acceptance. Because of this, it is necessary to focus on such nuances when selecting a filter:

  • The quality of paper and its density. Affects the filtering performance - the more uniform the thickness of the paper, the better the quality of filtration and less chance of dirt passing the filter element.
  • Winding density. The higher the quality of the filter, the higher the density of the winding and the better the performance of the fixture.
  • Uniformity of filling with dirt. When during the removal of the used filter element unevenness and irregularity of filling is noticeable, the purchase of such a device in the future should be abandoned or reduce the period of use up to 8-10 000 km.

How often to change the filter

To violate the terms of replacement means to approach the repair of the fuel system and the engine. Therefore, it is better to know what time limits are set by the manufacturer of your car.

  1. Each filter may have 30,000 km, another may have 120,000 km.
  2. Most often the part is changed when it is outside the fuel tank.
  3. You should change the filter early only if you are sure that mechanical particles or too much water got into the tank. In this case, it is better to flush the tank at the same time and replace the gasoline pump, if necessary.
  4. It is better to do a preventive replacement in the fall, because the filter has the hardest time in the winter. Thickened fuel goes through the element, and if it is already clogged, the fuel will not come in the necessary amount.

Why it is dangerous to use a "clogged" filter on a diesel

It has been noted many times before that it is quite dangerous to use a contaminated filter on a diesel engine. Such words are not an exaggeration, but a real statement of facts. This phenomenon is largely due to the fact that:

  • Firstly, the diesel fuel system is designed in such a way that it is extremely sensitive to the impurities present in the fuel;
  • Secondly, diesel fuel contains a huge amount of moisture, which, getting into the engine, can not only greatly reduce its service life, but even "kill" the engine.

Based on this information, you can make a basic list of those failures that will appear when using a "clogged" fuel filter on the diesel. The list is as follows:

  • Breakdown of fuel distribution mechanism (analog of injector and carburetor on gasoline engines);
  • failure of the fuel pump, fuel lines and other elements of the line through which unclean fuel flows;
  • malfunction of the engine and its internal components, which are caused by detonation due to the abundance of moisture in the fuel.

Important! Do not forget that replacing the diesel fuel filter - it is not so difficult and relatively fast. But it will be much more difficult to fight the problems that appeared after using a faulty unit. Therefore, we strongly recommend timely replacement of such an important part in the system of diesel cars.
