Some drivers forget to change the fuel filter in their car, which, however, can lead to to serious damage to her engine. However, how do we know that the fuel filter in question is for replacement. There are several signs that the filter is damaged and needs to be replaced. Who they are, we tell you now.
Among the main signs of a clogged or defective fuel filter, in the first place, it is worth mentioning difficulties in starting, misfires, as well as unstable engine operation in general. If the filter is clogged, insufficient fuel will flow to the engine.
Secondly, against the same background, a loss of power may occur and the performance of the car may decrease sharply or barely perceptibly. This depends on the degree of permeability of the filter.
The third sign of a faulty filter is overheating of the fuel pump and, as a result, its premature failure, notes the expert. If you have a problem with the fuel pump and a repair is necessary, you must also change the fuel filter.
Otherwise, if there are none of these signs, the fuel filter replacement interval depends on the type of car and the quality of the fuel. On average, most car manufacturers recommend changing the fuel filter every 30-50 thousand km.
But some models, especially diesel ones, may require more frequent replacement. Especially considering the quality of the oil sold in our country, it is highly recommended for diesel cars to change the filter every 15-20 thousand kilometers.
