Is it okay to run 7,500 km with oil meant for 5,000 km?

Why doesn't the electric car move after braking and applying power?

Here are the reasons why an electric car doesn't move after braking and applying power: 1. Damaged electronic components: The Hall sensor inside the accelerator (throttle) is damaged. The accelerator is crucial for electric cars, and the Hall sensor is vital for the accelerator, so damage to the Hall sensor will directly cause the vehicle to have no response when pressing the throttle even if there is power. To check if the Hall sensor is damaged, you can examine its rated voltage and current to see if they are within the specified range. Values above or below this range will cause the Hall sensor to malfunction. 2. Brake system failure: The brake power-off system is stuck or not reset, causing the brake system to remain engaged. In this case, the throttle may show "no response." Alternatively, there might be a broken control circuit or a faulty controller. The controller starts working after receiving the signal from the throttle. If the controller is short-circuited or faulty, the throttle naturally won't respond. 3. Motor failure: A motor failure will directly prevent the vehicle from operating, making the throttle useless. Identifying a motor failure is simple, as it is usually accompanied by smoke, sparks, or excessive temperature. Observing any of these signs indicates a motor failure. In such cases, it's necessary to visit a repair shop for maintenance.

Can the Original License Plate Be Retained During Vehicle Transfer?

For second-hand car transfers, the original license plate can be retained, but the plate itself cannot be transferred. The latest regulations on license plate retention: The original license plate can be retained if the vehicle has been used for at least one year, with a retention period of up to one year; the original plate can also be retained in cases of vehicle transfer, cancellation, or relocation; applications for retention can be made whether purchasing a second-hand car or a new car; all traffic violation records of the original vehicle must be settled before retention. The process for retaining the original license plate is as follows: The vehicle owner needs to prepare the "Motor Vehicle Transfer or Registration Application Form," the owner's ID card and a copy (non-local residents must also bring a residence permit), proof of the vehicle's origin, the vehicle's purchase tax payment or tax exemption certificate, the vehicle's annual inspection certificate, and relevant documents submitted during the vehicle's initial registration (for imported vehicles, additional documents such as the import certificate, the vehicle's complete factory qualification certificate, and the compulsory insurance certificate are required). The owner can then proceed to the relevant DMV window to complete the process of retaining the original license plate.

When Should the Purchase Tax Be Paid for a New Car?

The purchase tax for a new car must be paid within 60 days at the latest. According to Article 13 of the Provisional Regulations on Vehicle Purchase Tax of the People's Republic of China, taxpayers who purchase taxable vehicles for personal use must declare and pay the tax within 60 days from the date of purchase, and the vehicle purchase tax must be paid in one lump sum. This means that car owners must declare the tax within 60 days of purchasing the vehicle. If the vehicle purchased is an imported car, the declaration must also be made within 60 days of purchase. The payment of the vehicle purchase tax is a one-time lump sum, with the following relevant details: 1. Policy: The new policy states that from January 1, 2017, to December 31, 2017, passenger vehicles with a displacement of 1.6 liters or below are subject to a vehicle purchase tax rate of 7.5%. Starting from January 1, 2018, the statutory tax rate of 10% for vehicle purchase tax will be reinstated. 2. Vehicle purchase tax should be paid before license plate registration: It is not necessary to wait until the license plate is suitable for registration to pay the tax because the vehicle purchase tax does not require a license plate number. If the vehicle purchase tax is not paid within the prescribed period, a late fee of 0.05% of the overdue tax will be charged daily from the date of default.

What happens when a tensioner pulley is damaged?

When a tensioner pulley is damaged, the following situations may occur: 1. Abnormal noises: There will be noises at 1400-1500 RPM, and the noise will be louder under high power consumption. 2. Obvious resonance: The resonance will be very noticeable, with loud noises during rapid acceleration, accompanied by noise phenomena and insufficient power. 3. Brake failure: If the tensioner pulley is damaged while the car is in motion, it may result in loss of brakes and steering, leading to serious consequences. The belt tensioner pulley is used to adjust the tightness of the timing belt, preventing belt slippage and compensating for elongation caused by belt wear and aging, requiring a certain amount of torque.

Does the ETC card have a front and back side?

ETC cards have two sides, with the side containing the chip being the front. The front side should face the car window and be inserted into the card slot of the OBU device. Where can ETC be installed: For small vehicles such as cars and minivans, the OBU device is installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC installation position requirements: The height should be no less than 1.2 meters and no higher than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the front windshield, ensuring the chip is inserted into the OBU device.
