What is the Difference Between Gear Oil and Engine Oil?

Gear oil and engine oil differ in their performance characteristics: Engine oil primarily focuses on low-temperature performance, maintaining good fluidity in cold conditions; gear oil, on the other hand, emphasizes performance under high temperature and high pressure, as the pressure between gears is much higher than in an engine, and the operating temperatures are also significantly higher. Additionally, engine oil is weakly alkaline, while gear oil is strongly alkaline. Engine oil, also known as engine lubricant, serves to lubricate, clean, cool, seal, and reduce friction in the engine, and is composed of base oil and additives. Gear oil, referred to as transmission lubricant, is mainly made up of antioxidants, antifoaming agents, and rust inhibitors, and is used for lubricating various gears in transmissions, reducers, and differentials to prevent wear and sintering on gear surfaces.

What does 5w20 engine oil mean?

5w20 engine oil refers to the viscosity grade of the oil. The number 5 represents resistance to external low temperatures of -30 degrees Celsius, the W stands for Winter, and 20 indicates that the kinematic viscosity of the oil at 100 degrees is 20. Engine oil, also known as motor lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil is divided into mineral oil and synthetic oil. Mineral oil is refined from petroleum and is only used in some mid-to-low-end vehicles, while synthetic oil has become standard for mid-to-high-end vehicles. Synthetic oil is further categorized into semi-synthetic oil and fully synthetic oil. Fully synthetic oil is produced by cracking lighter components such as ethane and propane from crude oil or coal into ethylene, which is then recombined through complex chemical processes.

How to Start a Manual Transmission for Beginners

Method for beginners to start a manual transmission: 1. Insert the key, turn on the ignition switch, and start the engine. Normally, you need to observe the indicator lights on the dashboard; 2. Press the clutch pedal, shift the gear lever into 1st gear, and observe the surroundings of the vehicle to ensure safety. Then, release the parking brake lever, also known as the handbrake; 3. Lift the clutch pedal, first quickly lift the clutch pedal until the engine sound becomes lower, then slow down the lifting speed. When the vehicle body slightly shakes, pause the clutch pedal for a moment, while adding a little throttle, then slowly lift the clutch pedal, and then gradually increase the throttle. A manual transmission, also known as a manual gearbox, requires manually moving the gear lever to change the gear meshing device inside the transmission, thereby altering the gear ratio to achieve the purpose of shifting.

Is a Torque Converter a Clutch?

Torque converter is not a clutch. Torque converters are used in automatic transmission vehicles, while clutches are used in manual transmission vehicles. The torque converter is a hydraulic component consisting of a pump impeller, turbine, and guide wheel, installed between the engine and the transmission. It uses hydraulic fluid as the working medium to transmit torque, change torque, shift gears, and perform clutch functions. The clutch is located inside the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the gearbox, thereby cutting off or transmitting the power input from the engine to the transmission.
