The Difference Between Using 92 and 95 Octane Gasoline in Cars

About the difference between using 92 and 95 octane gasoline in cars, the introduction is as follows: 1. Different gasoline grades correspond to different engine compression ratios: The higher the grade, the stronger the gasoline's anti-knock performance. The sole criterion for selecting gasoline grade is the engine's compression ratio. The higher the compression ratio, the smaller the volume of combustible mixture is compressed, resulting in greater power and lower fuel consumption. 2. 92 and 95 octane gasoline have different octane values: 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. 3. 92 and 95 octane gasoline differ in power and fuel consumption performance: 95 octane gasoline has advantages over 92 octane in terms of power and fuel consumption because its isooctane content is higher than that of 92 octane gasoline.

How to Replace the Battery in a Mercedes-Benz GLS Key?

Below is some related information about the Mercedes-Benz GLS: 1. The Mercedes-Benz GLS is a crossover SUV from Mercedes-Benz. 2. In terms of appearance, the GLS features AMG styling, making it look very sporty. Its overall size remains largely unchanged, maintaining its robust and imposing presence. Among the many SUVs from Mercedes-Benz, I personally believe the GLS (formerly the GL) has the most balanced proportions. If you're looking for sheer masculinity, the G-Class is undoubtedly the top choice in the family. But if you want a vehicle with well-balanced proportions and a luxurious demeanor, the GLS should be your first pick.

What is the fuel tank capacity of the A4L?

Currently, there are 7 available models of the Audi A4L on sale. The quattro and quattro RS versions have a fuel tank capacity of 58L, while other versions have a capacity of 56L. This data is published by the automobile manufacturer, and owners who have purchased the Audi A4L can also check it on the vehicle's configuration sheet. The Audi A4L requires 95-octane fuel, with a fuel consumption of 6.1 to 7.3L per 100 kilometers. A full tank can cover a distance of 794 to 918km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank. This is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space is reserved to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

Why is the engine idle noise very loud?

If there is a buzzing sound inside the vehicle cabin during idle, it is highly likely to originate from the hydraulic power steering pump. If the noise can be heard while driving, it indicates that the power steering fluid is too dirty or there is an issue with the power steering pump. Below are the steps for replacing the engine oil: 1. Remove the old oil from the power steering fluid reservoir and clean it thoroughly, then reconnect only the oil supply hose after cleaning; 2. Extend the return hose of the power steering fluid reservoir and connect it to a container for collecting the old oil; 3. Place a funnel on the reservoir for easy refilling and prepare to add new power steering fluid; 4. Have someone inside the vehicle start the engine and immediately turn the steering wheel left and right; at the moment the engine starts, the person outside should begin adding new fluid to the reservoir. The disconnected return hose will continuously expel the old oil from the entire system and discharge new oil; 5. Reserve about half a liter of power steering fluid during refilling. When the return hose discharges new oil, stop adding fluid. Carefully observe the fluid level in the reservoir and instruct the person inside to turn off the engine when it drops to nearly empty; 6. At this point, since the power steering fluid in the reservoir is almost depleted, reconnect the return hose. After reconnecting, add sufficient power steering fluid to the reservoir. This completes the power steering fluid replacement process.
