Gear oil and transmission oil are the same. Transmission oil includes manual transmission oil and automatic transmission oil. Manual transmission oil is collectively referred to as gear oil, while automatic transmission oil has a higher grade and is also called drive oil. At the same time, ordinary gear oil cannot be used in automatic transmissions; automatic transmission oil must be used instead. Gear oil is mainly composed of petroleum lubricating base oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an important lubricating oil. It is used in various gear transmission devices to prevent tooth surface wear, scratches, sintering, etc., thereby extending their service life and improving power transmission efficiency. Gear oil should have excellent anti-wear and load-bearing properties as well as suitable viscosity.

Can You Wear Flat Sandals for Driving Practice?

You should not wear flat sandals for driving practice. Although traffic regulations do not explicitly prohibit driving in sandals, wearing sandals while driving poses safety risks. Safety risks of driving in sandals: Since practicing driving indicates a lack of proficiency, wearing sandals may cause your toes or the sandals themselves to get caught when operating the clutch, brake, or accelerator, leading to delayed pedal transitions and increasing the risk of accidents. Recommended footwear: thin-soled flat shoes: The shoe soles should have strong grip to prevent slipping, and they should not be too soft—moderate firmness is ideal. The shoes should also be breathable to avoid discomfort from sweating while driving. Slip-on styles are preferable for easy wear and removal.

Are there motorcycles with roofs like cars?

No, there are no motorcycles with roofs like cars. High-displacement motorcycles: High-displacement sports bikes have a stylish and eye-catching appearance, with powerful horsepower that leaves dust behind, but prolonged riding can be uncomfortable for the waist. Compared to sports bikes, low-displacement street bikes offer a more comfortable riding posture for daily commuting. However, during high-speed rides, the lack of a windshield can subject riders to strong winds. Retro-modified motorcycles: These models exude a sense of artistic flair, allowing riders to experience the satisfaction of customizing parts and creating a motorcycle that reflects their personal style. At the same time, lightweight scooters with an artistic touch offer simple operation and easy maintenance. Both types captivate with their intriguing charm, drawing people into nostalgic memories of the past.
