Selection criteria for diesel filter replacement

According to the actual situation of domestic oil quality, it is recommended that the replacement interval should not exceed 15,000 kilometers each time. The oil-water separator and the diesel filter should be replaced together. Of course, this is not inevitable. If your driving environment is bad (such as dump trucks, dump trucks in the top four, eight roads, etc.), the road conditions are different. You can only follow the replacement standards for construction machinery. The standard for construction machinery is once every 500 hours.

Because the filter has a service life, when a large amount of impurities in the diesel plugs the surface of the filter element, the permeability of the diesel will be very poor, which means that the pressure drop (resistance) is too large.
This will lead to insufficient fuel supply for power generation. Insufficient fuel supply will first cause insufficient combustion of diesel, black smoke from the car, lack of energy to run, and fuel consumption will increase correspondingly.
Secondly, the diesel can’t sufficiently cool and lubricate the engine plunger parts, which will cause serious wear and tear, so your oil pump is easy to break, which is caused by the filter!

Some people say that the replacement of 20,000 kilometers is based on standard oil products. It is undeniable that the quality of oil obtained in different parts of the world is not the same. Therefore, it is necessary to adjust the frequency of filters to suit local conditions. However, using a good quality filter can still protect the oil pump and the oil nozzle.
Golden hugeline filter products are made of original filter media, which has higher filtering accuracy and more effective protection of the engine. Among them, the oil-water separator is required to filter 95% of the diesel water, and the diesel filter has a filter efficiency of more than 98.6% for the impurities of 3-5 microns in diesel (equivalent to 1/20 of a hair).
Many repair shops attract customers with vicious competition at a low price, and then use poor filter cartridges. For a common rail car that uses this kind of filter, the fuel injectors and nozzles will wear out quickly. It will cost nearly 1,500 dollars to change a fuel injector assembly (6), the loss is huge, and the lesson is painful!
Poor oil quality, the use of substandard filters, and the use of common rail cars in an extremely harsh environment have led to doubts about common rail technology. In fact, the common rail car can be used with confidence by filtering the dirty diesel with a filter that meets the standards.
Everyone should pay attention to learning some basic maintenance knowledge in order to avoid being fooled and cheated anyway.
