Transmission fluid is gear oil, also known as transmission oil. Below is an introduction to the functions of gear oil: 1. It is a type of transmission lubricating oil used for lubricating various gears in transmissions, reducers, and differentials. 2. It helps prevent phenomena such as gear surface wear and sintering. 3. It extends service life and improves power transmission efficiency. Below is an introduction to the differences between gear oil and engine oil: 1. Different environments: Gear oil is a transmission lubricating oil used for lubricating various gears in transmissions, reducers, and differentials, operating in relatively low-temperature environments; engine oil is used inside the engine to lubricate internal components, enduring long-term high-temperature and high-pressure conditions, with higher oxidation resistance and stronger shear resistance. 2. Different functions: Gear oil prevents gear surface wear and sintering, extends service life, and improves transmission efficiency; engine oil cleans, lubricates, and cools the engine interior. 3. Both have lubricating properties, with engine oil being weakly alkaline and gear oil being strongly alkaline.

What is the best driving posture and distance?

The best driving posture and distance are: 1. First, adjust the backrest so that the seat back is tilted at an angle of 100 to 120 degrees, which can reduce the pressure on the lumbar spine; 2. Adjust the front and rear position of the seat so that when holding the steering wheel at the 3 and 9 o'clock positions, the arms are naturally bent at 120 degrees; 3. To avoid lower back fatigue while driving, adjust the seat height so that the hips and knees are at the same level, and do not let the knees be higher than the hips. If you cannot see the road ahead clearly, raise the seat slightly. The correct posture for the right foot while driving should be to press the brake straight and the accelerator diagonally, which means fixing the heel of the right foot in front of the brake pedal and using the heel as a pivot to switch between the accelerator and brake.
