The charging current for a car battery is related to its capacity, and a current of 6A can be used for charging. Charging time for the battery: If the battery is completely drained, it typically takes about 8 to 10 hours to charge. If a lower current is used for charging, it may take around 12 hours to fully charge. However, it's important to note that it's best not to wait until the battery is completely dead before charging. It is recommended to charge when the battery still has about 70% of its capacity remaining, in which case it only takes 6 to 8 hours to fully charge. If the battery voltage is too low, the car may have difficulty starting or may not start at all. Conversely, if the battery voltage is excessively high, it may damage the battery. Regularly check the battery voltage. If the voltage is below 11.8V, it indicates insufficient voltage, and you should turn off electrical devices and start the car to charge the battery. If the voltage drops below 10.8V, it means the battery is severely depleted, and a battery charger should be used for charging.

What does the engine oil grade 20W-50 mean?

The engine oil grade 20W-50 represents the oil viscosity, where W stands for winter use, the number 20 before W indicates low-temperature viscosity, and 50 refers to the viscosity at 100°C. Below are the relevant instructions for changing engine oil: Engine oil change instructions: Start the engine and bring it to operating temperature; drain the oil by locating the oil drain plug underneath the vehicle, unscrew it to allow the oil to flow out, and observe the oil color—if it appears black, it should be replaced promptly; unscrew the oil filter, as the oil flow slows down, this is when you can remove the oil filter for secondary draining. Engine oil change method: After all the oil has drained completely, replace the oil filter, install the new filter using a filter wrench, tighten it, then secure the drain plug, and lower the vehicle; pour an appropriate amount of oil into the filler port; start the engine and listen for any unusual noises, then pull out the dipstick to check if the oil has overflowed or reached the lower limit.

What is the reason for not being able to register the driver's license on the Traffic Management 12123 platform?

The Traffic Management 12123 platform cannot register the driver's license because the application license plate and the driver's license are not in the same location. Regarding driver's license registration: After completing the fourth subject of the driver's license test, when checking the driver's license information on the Traffic Management 12123 platform, the status of the driver's license shows as 'registered,' meaning the relevant information of the driver's license has already been recorded in the traffic management system. This proves that the driver of the license has obtained the qualification for the permitted vehicle type, but the driver's license is still in the mail or needs to be collected at the vehicle management office. Handling method when showing 'registered': Generally, if the driver's license status shows as 'registered,' it means the driver has not yet collected the license from the vehicle management office, or the license has not been mailed yet. According to relevant regulations, driving a vehicle on the road requires carrying the vehicle registration certificate and driver's license, and the car's windshield must have stickers such as the annual inspection label, compulsory traffic insurance label, and environmental protection label. Otherwise, there will be relevant penalties.

Can You Continue Driving If the Car Is Leaking Engine Oil?

You should not continue driving if the car is leaking engine oil. The reasons for oil leakage may include aging of the valve cover gasket, damage to the engine oil pan, aging of the drain screw gasket, cracking of the engine timing cover, damage to the crankshaft oil seal, loosening or damage of the oil pan drain screw, or loose installation of the oil filter element. Below is the relevant information: Reasons why you cannot continue driving: If engine oil leaks, it will lead to excessive oil consumption, which will first result in a loss of vehicle power. Secondly, as the engine oil level decreases, the cooling effect of the engine will weaken, internal components will experience poor lubrication, and various types of sludge will accumulate severely. Under such conditions, the engine will suffer severe wear, affecting its stable operation and reducing its lifespan. Solutions for car engine oil leaks: Replace the valve cover gasket; replace the oil pan sealing gasket; replace the drain screw gasket; remove and re-bond the engine timing cover; replace the crankshaft oil seal; tighten or replace the drain screw; replace the oil filter element.

The methods and duration for querying seized vehicles are as follows: Methods for querying seized vehicles: The vehicle owner can log in to any national public security bureau's motor vehicle inquiry system, enter the license plate number, and if the status column shows "locked," the vehicle is a seized or mortgaged vehicle and cannot undergo transfer or other procedures. Duration for seized vehicles: The People's Court may freeze the bank deposits and other funds of the person subject to enforcement for a period not exceeding six months. The seizure or detention of movable property shall not exceed one year, and the seizure of immovable property or freezing of other property rights shall not exceed two years.

What should I pay attention to when picking up my car after repair at a 4S shop?

When picking up your car from a 4S shop after repair, the main thing is to check whether the car has been properly repaired. You should carefully inspect both the repaired and unrepaired areas. First, check if the repaired parts are intact. For example, for sheet metal repairs, check if the surface is smooth and even, without any dents. Next, inspect the exterior paint to ensure the color matches, in case the 4S shop repainted the car without authorization after scratches. Pay special attention to whether any new scratches appeared during the repair process. Additionally, check if all interior equipment is functioning properly. Finally, verify that all fluid levels in the car meet the standard. If the repair was covered by insurance, check whether the 4S shop followed the insurance company's damage assessment for the repairs. When bringing your car to the 4S shop for repairs, make sure to record the odometer reading and the remaining fuel level in the car. You can take a photo with your phone. If the technicians at the 4S shop drove your car out without permission during the repair period, you can detect this by checking the remaining fuel level and odometer reading.
