If a car's fuel consumption is 7.8L/100km, then the average fuel consumption per kilometer is 0.078 liters. Based on the price of No. 92 gasoline at 6.5 yuan per liter, the fuel cost is approximately 0.5 yuan per kilometer. The cost per kilometer varies depending on the gasoline price. Relevant information about vehicle fuel consumption is as follows: 1. Factors affecting vehicle fuel consumption: The fuel consumption of a vehicle depends not only on the engine displacement, type of transmission, and vehicle size but also on the driver's habits and road conditions. 2. Practical fuel consumption: If you frequently drive on highways or elevated roads, the vehicle's fuel consumption will be relatively lower, as the roads are smoother, and the average driving speed is higher.

Seeing this fuel consumption issue, I really want to share my thoughts as I've been calculating my car expenses lately. A fuel consumption of 7.8 liters per 100 kilometers works out to approximately 0.078 liters per kilometer. Assuming the fuel price is 7.5 yuan per liter (a common price for 92-octane gasoline), the cost would be 0.078 multiplied by 7.5, equaling 0.585 yuan per kilometer. In terms of cents, that's about 58.5 cents, roughly 6 mao. In actual driving, fuel price fluctuations make a big difference—sometimes when prices rise to 8 yuan, it can push the cost to around 7 mao per kilometer. Since I drive more on highways, I've found that maintaining a steady speed can keep fuel consumption below 7.5 liters. Driving 10,000 kilometers a year, saving a few hundred yuan isn't hard. I recommend regularly checking tire pressure and sticking to scheduled maintenance—these small details add up over time and make driving more worry-free. With fuel prices constantly changing these days, it's best to use an app to check real-time data and avoid unnecessary stress.

What are the precautions for stopping and taking the card in Subject 2?

Here are the precautions for stopping and taking the card in Subject 2: 1. Avoid crossing the line: When entering the stop-and-take-card section, in addition to looking at the front of the car and aligning the body, you should also pay attention to the rearview mirror to prevent the rear wheels from crossing the line. 2. Find the right position: During the test, control the speed, find the correct stopping position, and stop in time. Otherwise, if you miss the correct position, you will not be able to take the card (swipe the card), or if you reverse to adjust, you will fail. 3. Control the distance: Just like parallel parking, the stopping position for stopping and taking the card must also be controlled well. You cannot cross the line, but you cannot be too far away either. If it exceeds 50cm, you will lose 100 points.

What is the purpose of installing a shark fin on a car?

Installing a shark fin on a car can enhance signal reception. Functional shark fin antennas need to be connected to the car's internal wiring and can integrate various powerful automotive electronic functions such as FM, GPS, and GSM, replacing and surpassing traditional rod antennas. Decorative shark fin antennas can also release static electricity and improve signal reception. Steps for installing a shark fin antenna: 1. Wrap the shark fin antenna with 3M tape, ensuring it is as flat as possible. 2. Remove the light on the rear seat of the car and take off the antenna base. 3. Determine and mark the correct position for the shark fin antenna. 4. Apply glue around the inner edge of the installation position, then peel off the tape on the shark fin antenna and align it to the marked position. 5. After installation, secure the shark fin with tape and remove the tape after 24 hours.
