Oil filter elements are installed on the left and right sides of the engine.

For vehicles without oil filter, there is only one oil filter, and the installation position of different vehicles is different. Some of them are installed outside the oil drain screw at the bottom of the right side of the engine, which can only be seen by disassembling the right cover of the engine. Some iron mesh plates that look like screen windows are installed at the bottom of the left side of the engine, and there is a big plug like a valve cover outside. Remove the screw, and you will see an iron mesh filter like a cup, which is the oil filter.
