Typically, the original manufacturer specifies a dedicated transmission oil. Replacement interval for transmission oil: Automotive automatic transmission oil generally needs to be replaced every two years or 40,000 kilometers, but the requirements vary for different vehicle models. For Japanese cars, it is recommended to replace the transmission oil every 40,000 to 80,000 kilometers. For vehicles that frequently drive on highways, it is advisable to replace the transmission oil every 40,000 kilometers.

How Long Does the Law Define a Car as Stock Vehicle?

There are no legal stipulations regarding the duration for stock vehicles, which generally refer to cars that remain unsold for 6 months after leaving the factory. Relevant details: 1. Outdoor stock vehicles: Prolonged exposure to sunlight accelerates paint deterioration and premature aging of rubber seals, while rain may cause electronic components to dampen, and dust can clog the vehicle's cooling system and drainage holes. 2. Indoor stock vehicles: During extended storage, the battery discharges, various fluids degrade, and components like tires develop deformation due to prolonged static contact with the ground. 3. Engine risks from long-term parking: The engine contains multiple lubrication channels where oil film can solidify if the engine remains inactive, potentially leading to clogged passages. This may result in severe damage to critical components like piston pins and valves, causing significant financial losses to owners.

Can I transfer to another driving school after registration?

It is possible to change driving schools after registration, but you will need to start learning and taking the exams from Subject 1 again, and all previous test results will be invalid. To transfer to another driving school, you should first go through the withdrawal procedures at your current driving school and then request the school to promptly withdraw your file from the driving management office. After the withdrawal, you can switch to another driving school. However, changing driving schools midway is generally not advisable because when you register, you submit necessary materials such as your ID card to the driving school, meaning your file has already been submitted to the driving management office by the school. Only after the materials are reviewed and approved will the driving school arrange for you to study and take the Subject 1 exam. Below are the three essential conditions for transferring to another driving school: 1. Both driving schools must belong to the same vehicle management office; 2. The original driving school must agree to your transfer; 3. The receiving driving school must agree to accept you.

What to Do When Engine Oil Pressure is Insufficient?

Solutions for insufficient engine oil pressure: It is recommended not to forcibly start the vehicle. Instead, wait for the vehicle to cool down and immediately check whether the oil level is within the specified range on the dipstick. If the oil level is below the minimum mark or no oil is detected, it is caused by oil shortage. Quickly replenish the engine oil with the correct specification and investigate the cause of the oil shortage. If the oil level is within the specified range, it might be a sensor malfunction. Such issues should be promptly addressed by a repair shop. Engine oil, also known as engine lubricant, serves multiple functions including lubrication, wear reduction, auxiliary cooling, sealing, leak prevention, rust and corrosion protection, as well as shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, providing additional beneficial characteristics. Additives are an essential part of the lubricant.

What to Do If One Reversing Radar is Broken?

Since the four sensors of the reversing radar operate independently, if one is damaged, you only need to replace the faulty reversing radar. First, you can check whether the power cord of the radar host is properly connected and if there is current supply. Also, check if the radar host wire is loose. If both are fine, the issue might be a damaged buzzer. Below is a detailed introduction to the reversing radar: The reversing radar typically has four sensors, installed at the rear or both sides of the car, with two on each side. Also known as a reverse parking sensor or parking aid, the reversing radar is a safety assist device used when parking or reversing. It consists of ultrasonic sensors, a controller, and a display (or buzzer). The reversing radar system alerts the driver about surrounding obstacles through sound or a more intuitive display, making reversing and parking safer. When the gear lever is shifted into reverse, the reversing radar automatically activates. When a sensor detects an object behind the vehicle, it emits a beeping sound as a warning. As the vehicle continues to reverse, the frequency of the alarm sound gradually increases, eventually turning into a continuous tone.

Where is the button to drain the windshield washer fluid?

Lift the car up, and there is usually a reservoir located below the right front wheel. Remove the small tube to drain the fluid. Here is some relevant information about windshield wipers: 1. Operating Principle: The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the motor are quite high. Typically, a DC permanent magnet motor is used, and the wiper motor installed on the front windshield is usually integrated with the worm gear mechanism. The worm gear mechanism serves to reduce speed and increase torque. Its output shaft drives a four-bar linkage, which converts continuous rotational motion into a left-right oscillating motion. 2. Basic Introduction: The wiper is a blade structure installed in front of the windshield, consisting of an electric motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Its main function is to clear rain, snow, and dust that obstruct the view on the windshield.
