How Much Engine Oil in the Car is Considered Normal?
1 Answers
Generally, the engine oil level in a car is considered normal when it is between the upper limit (MAX) and the lower limit (MIN). The optimal oil level is slightly closer to the upper limit. If the oil level is below the lower limit (MIN), it is not normal and requires maintenance. Additionally, when checking the oil level, the dipstick should be fully inserted. Below is more related information: 1. Functions of Engine Oil: "Engine oil" is an essential lubricant for ensuring the normal operation of the engine. Its specific functions include lubricating metal components, reducing friction between parts, dissipating the immense heat generated during engine operation, cleaning fine metal particles produced by wear, as well as providing sealing, vibration damping, and rust prevention. However, when adding engine oil, it is important to ensure the amount is neither too much nor too little. The oil level should be between the "low" (MIN) and "full" (MAX) marks on the dipstick. An oil level that is too low can lead to insufficient oil pressure, while an excessive oil level can increase the working resistance of the crankshaft and connecting rods and accelerate the formation of carbon deposits in the combustion chamber. 2. Precautions: After changing the engine oil in a car, the oil level should generally be between the lower line (MIN) and the upper line (MAX) on the dipstick. It is advisable not to exceed the upper line. Overfilling can cause issues such as foaming due to the crankshaft's agitation, which may damage the engine. Staying below the upper line is safe. After starting the engine, the oil level should ideally be in the middle to upper range. Overfilling may lead to problems like sluggish engine performance and oil seal leakage.
