What is the Normal Position for Engine Oil in a Car?

Generally, it should be maintained between the minimum and maximum marks on the dipstick. There are two key points to note when adding engine oil: 1. When selecting engine oil: It is necessary to strictly follow the oil grade specified in the car's user manual. If the same grade is not available, a higher grade can be used, but a lower grade should not be substituted; 2. When adding engine oil: The amount of oil added should be slightly below the standard mark. Excessive oil can increase the rotational resistance of the crankshaft, reduce the engine's output power, and the excess oil may enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emission, and increased fuel consumption.
The normal position of engine oil is between the min and max marks on the dipstick, which is between the lowest and highest lines. I often check the oil myself by first ensuring the car is parked on level ground and the engine has cooled for at least 10 minutes. Pull out the dipstick, wipe it clean, reinsert it, then pull it out again to check the oil level. If it's just above the min mark and below the max mark, it's perfect. Too high can increase oil pressure, leading to seal leaks or incomplete combustion; too low can wear out engine components and shorten engine life. Check it regularly every month, and the cold engine state is the most accurate. Avoid doing it when the engine is hot to prevent burns or misreading. This habit can save you from major repairs and extend your car's lifespan.
