There really is no single answer to this question. It is something that depends a lot on various circumstances: time of use, work performed by the machine... Despite this, it is true that an approximate time has been established in which theoretically a machine needs to change the diesel filter. It is recommended to make a change approximately every 250 working hours or at least once a year .
As we have mentioned, this can vary depending on the type of machine, the quality of the fuel that we are using or the working conditions. Therefore, something that is essential is to always follow the manufacturer's recommendations . In addition to this, it is not enough to change the filter every 250 hours. It is important to regularly check the filter to make sure if it is clogged or worn .
As a result of this, it is important to mention that a clogged or worn diesel filter can generate terrible problems in the machinery, hence the importance of carrying out periodic reviews of it. It can cause from starting problems to engine failure. It can even affect the fuel itself, reducing its efficiency and deteriorating other parts of the engine.
Something fundamental and that we must always take into account is the fact of the type of filter that we are using. As in everything, there are very different qualities on the market and we must choose the one that in the long run does not compromise the proper functioning of the machine. In cases like this, it is less counterproductive to make an investment in the quality of the part than not having to choose to change it several times due to its poor quality. As the saying goes, sometimes cheap is expensive, and in these cases quality comes first .
