A fuel consumption of 15 liters per 100 kilometers means that 15 liters of fuel are needed to travel 100 kilometers. Here are the reasons for a sudden increase in fuel consumption: 1. Insufficient tire pressure: Low tire pressure leads to increased fuel consumption. If the tire pressure is normal, check the tire wear. Severe tire wear often causes slipping, which also increases fuel consumption. 2. Excessive carbon deposits: A large amount of carbon buildup in the engine can result in higher fuel consumption, often due to the use of substandard fuel. The solution is to add a certain amount of cleaner when refueling. If the effect is not noticeable, it indicates significant carbon deposits in the engine, in which case it is best to take the vehicle to a 4S shop or repair shop for professional cleaning by a technician. 3. Oxygen sensor failure: A damaged oxygen sensor will cause the exhaust pipe to emit darker-colored exhaust gases during driving. The oxygen sensor should be replaced as soon as possible.

I understand the concept of 15 liters per 100 kilometers very simply—it means the car consumes 15 liters of gasoline to drive 100 kilometers. This fuel consumption is quite high; ordinary sedans typically range between 8-12 liters, while SUVs might be around 12-15 liters. Hitting 15 liters is noticeably costly in terms of both money and energy. From my experience, when driving high-displacement vehicles like SUVs or performance cars, especially in city traffic with the AC on, it's easy to exceed 15 liters. If a new car consumes this much, it might be due to its inherently fuel-thirsty design. For an older car that suddenly starts consuming this much, issues like engine or spark plug problems could be the cause. I recommend regular maintenance, checking the air filter and engine oil to prevent minor issues from escalating. Long-distance highway driving might save a bit of fuel, but for daily commutes of 20 kilometers, spending dozens of yuan a day on gas can be quite a burden. Compared to fuel-efficient hybrid cars, which only consume 4-6 liters, the difference is significant. It's essential to weigh your needs carefully when considering a car change.

How to Remove a Car Sunroof?

Take out a small flat-head screwdriver and gently pry open the trim panel along the gap with the small flat-head screwdriver. Be careful to do it lightly to avoid breaking the plastic clips inside. Remove the right-side screw. Take out a T-20 spline and use it to gently remove the screw. Keep the removed screw safely. There is a screw on the left side securing the sunroof switch. Remove the second screw and keep it safely for reinstallation. Take out the small flat-head screwdriver again and gently pry open the clips on both sides with it. This will separate the sunroof switch from the headliner. Take out the T-20 spline and use it to remove this screw. Disconnect the wiring harness plugs at the sunroof switch—there are three in total—one by one.

What to Do When a Car's Valve Core Leaks Air?

If you find that the valve core of your tire is leaking air, the cause is likely due to aging of the valve stem. In this case, you need to replace the old valve stem with a new one, which involves cutting off the old valve stem and installing the new one. The rubber washer under the screw is usually the cause of the valve core leaking air. Therefore, before installation, make sure to clean any debris around the installation area of the valve stem on the rim. Then, cut a section from the old inner tube that includes the valve stem, and cut out a circle about 2 centimeters in diameter around the valve stem. Place one rubber circle onto the valve stem and install it onto the rim. Then, fit another rubber circle over the valve stem on the outside of the rim.

What are the four steps to start a car?

Adjust the front and rear distance. For manual transmission, mainly adjust the left foot. When the clutch is fully depressed by the sole of the foot, there should be a slight margin left. Fasten the seat belt. Insert the key into the ignition lock, turn on the ignition switch, then observe whether all gauges are functioning normally, start the engine, and engage the correct gear. Turn on the left (right) turn signal and honk the horn as a signal, while observing the front, sides, above, and rearview mirrors of the vehicle to check for any obstacles that may hinder starting. Release the handbrake, slowly release the foot brake, and the vehicle will move forward. For manual transmission, gradually release the clutch, move the right foot to the accelerator pedal, and gently apply throttle.

How to Check If a Vehicle Has Been Transferred to Someone Else?

You can bring your ID to the vehicle management office to inquire about the vehicle information under your name, or check with the local traffic police team to see if you have any cars registered under your name. On the vehicle violation inquiry platform, enter the vehicle information and license plate number. If you can only retrieve the information by entering the original owner's vehicle details, it indicates that the transfer has not been completed successfully. You can also inquire with the insurance company about the vehicle's insurance personnel to determine whether the vehicle has been transferred. When there are issues with the vehicle, such as involvement in a car accident, failure to undergo annual inspection, stolen vehicles, or smuggled vehicles, the transfer cannot be processed through normal procedures.

How to turn off the TC light on a Buick?

The owner accidentally touched the traction control switch next to the gear shift lever. The owner can simply turn the control switch back on to deactivate the TC light. If the TC light remains on after turning off the traction control switch next to the gear shift lever, it indicates a malfunction in the traction control system, and the vehicle should be taken to a repair shop for inspection. TC stands for Traction Control system. When the ABS detects wheel slippage, the traction control system applies braking to the slipping wheel. Possible causes of the malfunction include: engine solenoid valve failure; dirty engine oil clogging the solenoid valve filter screen; or wear and tear on the actuator gear and impeller.

How to Deal with Water Stains on Car Windows That Won't Wipe Clean?

Pour the cleaner onto a towel or sponge and wipe the glass to remove water stains. You can also use alcohol to remove them. First, wipe the glass with a damp cloth, then use a dry cloth dipped in a small amount of alcohol or high-proof liquor to wipe the glass, which can also remove water stains. Alternatively, you can spray vinegar or soda water on the glass and wipe it with a towel to remove water stains. For small scratches, squeeze toothpaste onto a polishing cloth, apply it to the scratches, and then wipe the toothpaste clean with a damp cloth.
