Truck diesel Fuel filter A5410920805 for Benz

How often is the best time to change the fuel filter?

The fuel filter must be replaced every 30,000 kilometers in normal use. If the fuel impurity content is large, the driving distance should be shortened accordingly. But generally we recommend replacing it every 20,000 kilometers. For the specific best replacement time, please refer to the instructions on the vehicle user manual.
Usually, the replacement of the fuel filter is carried out when the car is undergoing major maintenance, and it is replaced at the same time as the air filter and the oil filter. However, in reality, it can be extended appropriately according to the conditions of the car engine, because the current gasoline production technology level is relatively high, from production to sales are relatively closed, gasoline is much cleaner, fuel filter clogging is rare, and driving is 56,000 yuan. Kilometers are no problem.
When replacing the filter, do not choose a low-quality fuel filter, because the filter element of the inferior fuel filter is made of poor material, which not only has poor filtering effect, but is soaked in the oil for a long time, and the filter element itself will fall off the filter layer and block the oil. As a result, the fuel pressure is insufficient and the vehicle cannot be started. At the same time, it will cause abnormal pressure in the fuel system, which directly leads to insufficient engine power or insufficient combustion, damages valuable components such as the three-way catalyst and oxygen sensor, and causes huge economic losses.
