The transmission of the BMW X3 is the 8-speed Steptronic automatic transmission provided by ZF Friedrichshafen. Transmission Introduction: A transmission is a mechanism used to change the speed and torque from the engine. It can fix or change the gear ratio between the output shaft and the input shaft in steps, also known as a gearbox. The transmission also includes a power output mechanism. Most transmission mechanisms use ordinary gear transmission, while some use planetary gear transmission. Ordinary gear transmission mechanisms generally use sliding gears and synchronizers, etc. Transmission Composition: The transmission consists of two parts: the transmission mechanism and the transmission control mechanism. The main function of the transmission mechanism is to change the value and direction of torque and speed; the main function of the control mechanism is to control the transmission mechanism to achieve the transformation of the transmission ratio, that is, to achieve gear shifting to change speed and torque.

Can Expired Engine Oil for Small Cars Still Be Used?

Expired engine oil for small cars cannot be used. Reasons why it cannot be used: Engine oil is a highly water-absorbent substance. Over time, it absorbs moisture from the air, leading to oil degradation. The chemical composition of expired oil may have already changed, and using it can negatively impact the engine. Additionally, during the oil's deterioration process, impurities may form. These impurities, when introduced into the engine, can accelerate carbon buildup, potentially leading to severe consequences if left unchecked. Storage methods for opened engine oil: Seal the oil immediately after opening. After maintenance at a 4S shop or repair facility, the oil bottle cap should be tightly screwed back on. Once sealed, store the oil bottle in a dry and cool place, ensuring it is not exposed to sunlight to prevent oxidation reactions in the oil. When using long-stored oil during the next maintenance, do not pour it entirely into the engine. Retain a small portion, as prolonged storage can lead to slight moisture accumulation at the bottom of the bottle, which could impair engine performance or cause adverse effects if added.
