Why machine oil decreases without smuggling? There are several possible reasons why engine oil may be running low without an obvious leak. Here are some possible causes: Evaporation: Motor oil can evaporate due to the high heat inside the engine during the combustion process, especially in extreme conditions such as driving a car at high temperatures for long periods. Once the oil evaporates, this can lead to a low amount of oil in the engine. Oil combustion: Some amount of oil may burn inside the combustion chamber due to leakage into the air or fuel duct. This can also lead to a lack of oil in the engine. Oil use: The normal use of the car can be a reason for the lack of oil in the engine, as a small amount of oil is consumed during the process of normal operation, especially in engines of old design. Invisible Leak: Invisible leaks may occur from various parts in the engine, such as rings, valves, and seals. There may not be obvious oil leakage, but a small amount of oil may disappear over time. Ventilation System Malfunction: There may be a defect in the engine's ventilation system, such as the PCV valve (Carbon Positive Ventilation Valve), which allows air and steam to escape from the crankshaft, and this may result in loss of oil.
