The car oil filter is filled with oil. Introduction:
1. There is no need to fill up. The engine is the heart of the engineering machinery, which maintains the operation of the entire machine. During the operation of the engine, metal wear debris, dust, carbon deposits oxidized at high temperatures, colloidal deposits, and water are constantly mixed with lubricating oil;
2. The function of the oil filter is to filter out debris, colloids and moisture in the oil, deliver clean oil to each lubrication part, extend its service life, and play a pivotal role in construction machinery;
3. A small oil filter element may seem inconspicuous, but it has an irreplaceable position in construction machinery. Machinery cannot be separated from oil, just like the human body cannot be separated from healthy blood. Once the human body loses too much blood or the blood undergoes qualitative changes, life will be seriously threatened.

How to replace the oil filter:
1. First start the vehicle for about 1 minute to allow the oil to flow fully, then turn off the engine, open the oil filler cap, use a tool to loosen the filter and the oil bottom screw, place the oil pan under the oil bottom screw, loosen the oil bottom screw completely, and drain the old engine oil until it stops flowing;
2. Then tighten the oil bottom screw and wipe off the excess oil with a cotton cloth. Unscrew the old machine filter, it is recommended to put a cotton cloth on your hands carefully, apply engine oil to the seal ring of the new machine filter, and tighten it in a clockwise direction. Add new oil from the oil filler port. It is recommended to consult the 4S shop in advance for the amount of addition, and tighten the filler cap after adding it;
3. Restart the engine for 12 minutes and observe whether the oil bottom screw and the engine filter leak. The position above the center line of the oil scale in the standard position has been replaced.
