Has the Age Limit of 70 for Small Car Driver's Licenses Been Removed?

To better meet the new demands of an aging society, the new measures for optimizing the business environment by the public security and traffic management authorities have removed the upper age limit of 70 for applying for small car, small automatic transmission car, and light motorcycle driver's licenses. More details about the new measures for optimizing the business environment by the public security and traffic management authorities are as follows: 1. Further promotion of cross-region handling: Promote nationwide "one certificate for all" for motorcycle driver's license exams, implement cross-region transfer of motorcycle registration, trial province-wide handling of private car registration with ID cards, and implement cross-region handling of temporary license plates for used car exports. 2. Further promotion of "streamlining administration and delegating power": Expand the scope of motor vehicle exemption from inspection, relax the age limit for applying for small car driver's licenses, optimize the application conditions for large and medium-sized passenger and truck driver's licenses, expand the scope of medical institutions for physical examinations, and facilitate shared vehicles for families with disabled members.

Does Turning on the Air Conditioner Affect Fuel Consumption?

Turning on the air conditioner does affect fuel consumption, and the impact is relatively significant. The reasons why turning on the air conditioner affects fuel consumption and the scenarios where it does not are as follows: Reasons why turning on the air conditioner affects fuel consumption: Turning on the air conditioner consumes more fuel primarily because the air conditioning compressor requires a significant amount of power to operate. In contrast, the variation in fan speed has a minimal impact on power requirements. Therefore, within a certain speed range or wind resistance, using the air conditioner increases fuel consumption, while turning it off saves fuel. The impact of air conditioner fan speed on fuel consumption is negligible, including when only using the heater in winter. Scenarios where turning on the air conditioner does not affect fuel consumption: There is a specific condition under which turning on the air conditioner does not increase fuel consumption: when the engine coolant temperature rises above 73 degrees Celsius, using the air conditioner for heating will not affect fuel consumption. Apart from this, using the air conditioner for cooling or heating will impact the vehicle's fuel consumption.

Is it necessary to change the rear axle differential oil?

It is indeed necessary to replace the rear differential oil. The general replacement interval for differential oil is between 80,000 to 100,000 kilometers. Replacing the differential oil helps prevent excessive wear of the vehicle's differential gears, which could lead to differential damage. Differential oil serves as the lubricant for the rear axle gear transmission mechanism, also known as gear oil. Its primary functions are lubrication and cooling. Due to the varying positions of gear axes and different tooth profiles, the contact stress and relative sliding speed at the meshing surfaces of gears differ significantly, necessitating the use of different gear oils. Failure to replace differential oil can result in increased friction among the gears within the differential structure, leading to higher vehicle fuel consumption and, over time, damage to components such as the differential and differential lock. The functions of differential oil include forming an oil film on gear meshing surfaces to provide lubrication, thereby reducing friction resistance and extending component lifespan; and dissipating heat generated by friction pairs through fluid flow, serving a cooling purpose. Its working principle involves the lubricant in the differential reaching very high temperatures during high-speed driving, far exceeding the temperature of engine oil, ensuring the vehicle's normal operation.

Location of the Porsche 718 Fuel Tank?

Here is the relevant introduction about the location of the Porsche 718 fuel tank: 1. The Porsche 718 differs from the front-engine design of ordinary cars: It adopts a mid-engine, rear-wheel-drive layout. The engine is located behind the driver. To keep the fuel tank away from the engine, the fuel tank is positioned at the front of the vehicle, hence the fuel filler cap is located on the fender of the Porsche. It not only features a front trunk but also a spacious rear trunk, significantly enhancing practicality. 2. Additional Information: The Porsche 718 is stylish and elegant, with an attractive front design and sleek body lines. It offers excellent comfort, with comfortable seats and fast air conditioning cooling.
