15W-40 engine oil with a viscosity of 40 is more suitable for European cars. Additional information is as follows: 1. Engine oil viscosity: There is a characteristic of engine oil viscosity—higher viscosity provides better sealing but increases fuel consumption in the engine. At idle, higher viscosity oil results in lower noise, while during driving, higher viscosity oil leads to higher noise. Lower viscosity oil, on the other hand, has fuel-saving characteristics. 2. 5W-40: 5W-40 is the viscosity grade of engine oil, and it can be used in any car. However, this grade of oil is more suitable for use in summer and autumn climates.

What are the effects of driving a sedan through deep water?

If a car passes through deep water without stalling, it will not cause significant damage to the vehicle. However, it is essential to inspect and clean the car as soon as possible, checking whether the brakes are functioning properly. After successfully driving through water, avoid accelerating immediately and continue driving at a low speed for some time. Below is more information about driving through water: 1. Reasons for vehicle impact: Whether driving at high speed through accumulated water has an effect mainly depends on the depth of the water on the road and the height of the waves generated by the vehicle passing through at high speed. If the water reaches the height of the vehicle's air intake, it can directly cause the engine to stall. 2. What to do after stalling: If the engine stalls, do not attempt to restart the vehicle immediately. Instead, call your insurance company and a repair service to wait for assistance. After towing the car to a repair facility, check for water ingress inside the engine. 3. Points to note when driving on waterlogged roads: Driving on waterlogged roads can reduce the car's braking performance and increase the risk of skidding. Drivers should hold the steering wheel with both hands to maintain balance, drive straight and at a low speed. When turning, apply the brakes gently to prevent the tires from locking up and causing the vehicle to skid.

Why does the BMW 116 experience intermittent idling vibration?

BMW 116 intermittent idling vibration may be caused by severe engine carbon deposits or ignition system issues. Severe engine carbon deposits: The most common cause of car vibration is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold-start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making ignition difficult. In this situation, the engine will only start easily after the carbon deposits have absorbed enough gasoline to reach saturation. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, making the air-fuel mixture too rich. This fluctuation between lean and rich mixtures causes idling vibration after a cold start. The lower the temperature, the more fuel is required for cold starts, and the presence of carbon deposits will significantly affect whether the cold start proceeds smoothly. Ignition system issues: Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or inadequate spark plug firing can also lead to such fault symptoms.

Can the temporary license plate still be used on the 16th if it expires on the 16th?

A temporary license plate that expires on the 16th can still be used on the 16th; you are allowed to drive with it on the expiration day. Penalties for exceeding the validity period: New vehicles using temporary license plates must not exceed 15 days. Owners should promptly apply for official license plates from the vehicle management authority. After expiration, penalties may include vehicle impoundment, fines, and a deduction of 12 points from the driver's license. Methods to register after the temporary license plate expires: Towing: Tow the vehicle to the vehicle management office for registration, but this method can be costly. If official license plates are not issued on the same day, the owner would need to tow the vehicle back home, making this method not recommended. Reapplying for a temporary license plate: Temporary license plates are generally valid for 15 days. Owners should apply for official license plates within the temporary license's validity period. If the temporary license plate expires and official plates have not yet been issued, reapplying for a temporary license plate is the most cost-effective method. However, temporary license plates can only be applied for a maximum of three times.

What is the fuel tank capacity of the 4008 in liters?

The fuel tank capacity of the Peugeot 4008 is 53 liters, as officially announced. The recommended fuel grade for the Peugeot 4008 is 92, with a fuel consumption of 6.2-6.4L per 100 kilometers. A full tank can cover a distance of 828 to 855 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank. The fuel level is usually observed through the fuel gauge inside the vehicle. 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 the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit, and there is additional space from the safe limit to the tank opening. This space ensures that the fuel can expand when the temperature rises without overflowing the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

Can the Issuing Location of a Driver's License Be Changed?

Yes, you can change the issuing location of your motor vehicle driver's license. You need to visit the vehicle management office or the traffic management department of the public security authority at the original issuing location to complete the transfer-out procedures for the motor vehicle. After obtaining the transfer-out documents, you can then complete the transfer-in procedures in another region, thereby completing the transfer of the driver's license issuing location. Below is an introduction to the process: Driving school registration time: When applying for a motor vehicle driver's license at a driving school, the registration process takes about half an hour to complete. After registration, you will wait for the driving school's notification to undergo a physical examination. Once the physical examination is completed, you will participate in the study for the first subject of the driver's license. After meeting the required study hours, you can take the exam. Other subjects should be completed in the same order. There is no need to repeat the physical examination within six months. Time to obtain a motor vehicle driver's license: Under normal circumstances, it takes about 45 days to obtain a motor vehicle driver's license, with the maximum time not exceeding three years. This period starts from the completion of the first subject exam of the driver's license. If this time limit is exceeded, the eligibility for the driver's license exam will be canceled, and you will no longer be able to take the exam.

Can Stepping Hard on the Accelerator Damage the Battery of a New Energy Vehicle?

Stepping hard on the accelerator of a new energy vehicle can indeed damage the battery. Frequently pressing the accelerator aggressively will affect the battery's lifespan, as it causes the power battery to discharge with high current frequently. It is well known that if the discharge current is too high, additional lithium ions are consumed to compensate, leading to battery degradation. Charging Temperature: For the battery itself, charging in excessively high or low temperatures can have adverse effects. The electrolyte used in lithium batteries is an organic system, which significantly slows down the charging speed in low temperatures and may prevent a full charge. Discharging is similarly affected. In contrast, high temperatures enhance battery performance, allowing for very fast charging. Parking Location: Modern new energy vehicles are equipped with lithium batteries, which accelerate aging if exposed to temperatures exceeding 60 degrees Celsius. Therefore, especially in summer, it is important to pay attention to where the vehicle is parked. It is best to park in a shaded area to avoid prolonged exposure to high temperatures. In winter, it is also necessary to keep the new energy vehicle warm.
