Each motorist must necessarily conduct periodic maintenance of his "iron horse". First of all, it allows you to eliminate malfunctions that have not yet shown themselves, which can "get out" the most uncomfortable moment, so to speak, according to the law of meanness. The second positive action is the prevention of such malfunctions.
Each maintenance involves checking the tightness of the mounting bolts, especially the suspension. Well, another mandatory point is the addition or replacement of consumable fluids, as well as filter elements. They play a huge role in the life of the car. For example, replacing the oil filter increases the pressure in
the lubrication system, and therefore, increases the resource.
Fuel filters pass fuel through themselves, which is logical, and then it falls into the cylinders, so the state of the latter directly depends on the state of the former.
If the smallest abrasive particles get into the engine cylinders, then its mirror will be scratched, and scratches that will not even be visible on other surfaces lead to a loss of compression, which consists of just such trifles.
The oil filter can be replaced even without an oil change. Many will say that this makes no sense, in fact, this is far from the case. Replacing the oil filter allows you to remove all contaminants that have accumulated in it from the engine, since there is a chance of such debris entering between the mating parts of the engine, although it is small. Here again it is worth recalling the law of meanness.
Naturally, if the engine oil was replaced, the oil filter must also be replaced, since the new oil has a lower viscosity, and it is simply able to wash the filter itself. Car filters are not only installed on the engine. They can be used, for example, in gearboxes. As a rule, they are automatic, and have great performance. The speed in such boxes is simply huge, and the torque exceeds five hundred Nm. In this case, the entry of any smallest particles between the gears will lead to the immediate failure of the shaft on which they are dressed. Well, since their productivity is great, it is logical to assume that repairs will be expensive.
Among other things, replacing the oil filter allows you to determine what condition the engine is in. If at the same time his behavior has changed markedly, especially with a parallel oil change, then the engine will serve his master faithfully for a long time to come. If the characteristics remained the same, then the repair is not far off. Of course, there is a possibility that the oil and filters were in good condition, but then a replacement would not be required. Then we can only rejoice, because in the first case you will have a good engine for a long time, and in the second - you are just a caring car owner.
Naturally, there is no universal scheme of action in such a situation, there is an approximate plan of action, following which you can maintain the engine, and the whole car as a whole, for a long time.
