Basically, the scale of the oil dipstick is also different for different models. The scale on most engine oil dipsticks is the highest 1L liquid level, not the liquid level of all engine oils. If your oil dipstick is one-third missing, it does not mean that all the engine oil is missing one-third.
In addition, since engine oil lubricates the engine, the metal parts (pistons) that move up and down in the gasoline combustion chamber (cylinder) are lubricated by engine oil, so there will be oil on the walls of the combustion chamber. . When gasoline burns, engine oil will also be burned together. Therefore, engine oil will be consumed during normal use. But excessive consumption of engine oil is problematic. If the oil light alarm appears, the exhaust gas is blue-black, the power is insufficient, and the vehicle is shaking, it means it is burning oil
