What is the difference between 95 and 92 gasoline prices?

95 gasoline is slightly more expensive than 92 gasoline. This is because 95 gasoline has a higher octane rating and fewer impurities, resulting in higher refining costs. Generally, the fuel tank of a vehicle will have the gasoline grade recommended by the manufacturer. You just need to refuel according to the grade indicated on the fuel tank. Here is some information about 95 and 92 gasoline: 1. 95 gasoline has higher combustion efficiency than 92 gasoline during medium to high-speed operation. However, 92 gasoline is more economical during low to medium-speed operation. 2. The gasoline grade is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. 95 gasoline has a higher octane rating, while 92 gasoline has a slightly lower octane rating. The octane rating of gasoline directly determines its anti-knock quality.

What are the reasons why a car cannot be turned off?

The reason why a car cannot be turned off is likely due to damage inside the ignition switch. The ignition switch has ACC, ON, and START positions. Turning to ACC powers the car's electrical equipment; ON powers the ABS (Anti-lock Braking System), AIRBAG (airbag), fuel pump, and ECU power supply, among others; while START is for ignition. Solutions for not being able to turn off the car are as follows: 1. Directly disconnect the fuel line switch. This mechanical fuel line switch varies in location depending on the car model—some are under the seat, while others are on the lower left side of the steering wheel. 2. For electronically controlled diesel engines, similar to car keys, they only power on when in the ON position, with the ECU controlling the fuel injectors to spray fuel. Therefore, turning off the key for such diesel engines stops the fuel injectors, effectively cutting off the fuel supply.

How to turn on the high beam of Nissan Qashqai?

To turn on the high beam of Nissan Qashqai, follow these steps: Turn the end of the light control lever forward to the second gear to turn on the low beam. In the low beam state, gently push the light control lever forward to switch to the high beam. Additional information: 1. It is generally best not to use high beams when driving in the city because the lighting conditions are usually good. The high angle of the high beam can easily dazzle oncoming drivers and pedestrians, affecting their vision and posing safety risks. It is also considered impolite driving behavior. However, alternately turning the high beam on and off at night can replace the horn to alert pedestrians and vehicles around you, avoiding excessive noise. 2. You can use the high beam when driving on highways or in rural areas without streetlights to expand your field of vision. However, when encountering oncoming vehicles, switch to the low beam for safety and courtesy. 3. When driving at low speeds, the engine's power generation is insufficient, and the battery is in a state of negative charging. Using the high beam can affect its lifespan. Additionally, using the high beam at low speeds at night will also increase the vehicle's fuel consumption.
