Is It Normal for Fuel Consumption to Increase After Maintenance?

It is normal for fuel consumption to increase after maintenance. Here are the specific reasons: 1. Increased oil viscosity: When using the same type of oil, the newly replaced oil will have higher viscosity compared to oil that has run for 10,000 kilometers. This naturally creates greater resistance, leading to slightly higher fuel consumption under the same road conditions and driving style. This situation usually diminishes after a few hundred kilometers of driving. 2. Replacement of brake pads: After installing new brake pads, the friction gap is relatively smaller, which means the resistance during braking is slightly greater, resulting in a slight increase in fuel consumption. This will normalize after the brake pads' break-in period. 3. Slightly overfilled oil: If the oil level is too high, the crankshaft in the oil requires more energy to rotate, increasing the engine's load and consequently raising fuel consumption.

Is it okay to drive in first gear with the clutch pressed?

Driving in first gear with the clutch pressed is not advisable. The speed of a car depends on its own gravity and inertia. Once the braking system of the car fails, the direct consequence is that the driver loses control of the vehicle. Tips for driving in first gear: When braking in first gear, the correct method is to press the clutch. Since the speed is relatively slow in first gear, not pressing the clutch while braking can easily cause the vehicle to stall. For manual transmission vehicles, in low-speed situations like first gear, the best way to decelerate without stalling the engine is to press both the clutch and the brake simultaneously. Precautions for driving: Apply light braking over a long distance when approaching a red light. This is a common technique used by many drivers on the road, especially in urban areas with frequent traffic lights, to maintain a safe distance from the vehicle ahead. Use engine braking wisely when going downhill. Avoid pressing the clutch when descending a slope and rely on the engine's own braking force to control the speed.

What are the symptoms after a sedan gets waterlogged?

Check the air filter to see if there are obvious signs of water ingress on the air filter and the lower housing of the air filter. Below is relevant information about vehicle wading: 1. Introduction to vehicle wading: As the name suggests, vehicle wading refers to driving a vehicle on low-lying, waterlogged roads, passing through water. This usually occurs during rainy weather in low-lying areas where poor drainage leads to water accumulation on the road. 2. Precautions for vehicle wading: Before wading, observe the road conditions carefully; during wading, maintain steady power; after wading, check the electrical system. If a car stalls in water, the main reason is usually water entering the exhaust pipe, and in some cases, electrical damage may also occur. Once a car stalls in water, do not attempt to restart it, as this may cause water to enter the intake manifold and damage the valves, or in severe cases, lead to engine failure. Instead, the car should be towed to a 4S shop immediately for professional handling.

What lights to use when making a right turn at an intersection at night?

Quickly turn the high beams on and off a few times to signal that a vehicle is approaching. At the same time, the right turn signal should also be activated. Below is relevant information: 1. No traffic lights: Turn on the low beams. If passing through an intersection without traffic signal control, you should slow down and alternately flash the high and low beams as a signal. 2. No illumination: Under normal circumstances, only the low beams are needed for night driving. If you encounter a completely dark road ahead with no street lighting facilities, the high beams should be turned on. If you are about to meet another vehicle, switch to low beams in advance and wait until the meeting is over before deciding whether to turn the high beams back on based on the situation.

Will a Power Bank Explode in the Car During Summer?

Power banks left in a car during high summer temperatures may self-ignite or explode. This is because most power banks contain lithium batteries, which are highly prone to explosion when exposed to sunlight in a confined car environment where temperatures can exceed 80 degrees Celsius. Therefore, it is best not to leave power banks in cars, especially for extended periods, as this poses significant safety risks. Below is some related information about power banks: 1. Introduction to Power Banks: A power bank is a device that can directly charge mobile devices and car batteries, equipped with its own energy storage unit. The main types available in the market today are multifunctional power banks, most of which come with standard USB outputs. They can generally meet the charging needs of common mobile devices such as smartphones, MP3 players, MP4 players, PDAs, PSPs, Bluetooth headsets, digital cameras, and other digital products. Essentially, a power bank is a convenient, portable, high-capacity power source that integrates energy storage, voltage boosting, and charging management into one portable device. 2. Functions of Power Banks: Power banks can charge mobile devices directly via an AC power source using their built-in charging plug and also feature their own energy storage unit. They function as a hybrid between a charger and a backup battery, simplifying the need for an additional charging plug compared to backup power sources. Unlike regular chargers, they come with their own energy storage, providing a backup power supply for digital products when no direct power source is available or when traveling.

Do I need to pay again when transferring to a different driving school?

Transferring to a different driving school requires additional payment for the following reasons: 1. Driving school factors: The new driving school is not affiliated with the original one, so you will need to pay for training fees/registration fees again. 2. Exam factors: If you have passed certain subjects at the original driving school, you may need to reapply for exams at the new driving school, which is equivalent to retaking subjects one through four. The transfer must be approved by the instructor. You will need to withdraw your records from the original driving school, negotiate withdrawal and refunds with the instructor, and then take your student records to the new driving school for affiliation. The instructor will help submit your records to the vehicle management office for review. Once approved, you can continue with the exams.
