My car is a modern Tucson. I want to ask, is it 40 thousand kilometers to change gear oil?

The maintenance of 40,000 kilometers mainly includes: replacing the oil machine to filter the brake fluid, disassembling and checking the brake pads, lubricating and cleaning the throttle nozzle, checking or replacing the spark plug, checking the spare tire for wheel balance transposition, and checking the lighting of the whole vehicle, which is generally carried out after 50,000 kilometers. If you run often, you can also change.
