Can engine oil opened for one year still be used?

Engine oil that has been opened for one year cannot be used because it has been too long. Once the oil cap is opened, it should be used as soon as possible; otherwise, the oil will deteriorate, and its lubrication performance will decrease. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts, thereby reducing wear; 2. To bring heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine; 3. To circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil. Signs that indicate the need to change the engine oil include: 1. Checking the viscosity of the oil—if there is no viscosity, the oil needs to be changed; 2. The color of the oil turns black; 3. Excessive black particles, metal shavings, or carbon deposits in the oil; 4. The smell of the oil is abnormal.

Should Snow Chains Be Installed on Front or Rear Wheels?

Whether snow chains should be installed on front or rear wheels depends on the vehicle type: for front-wheel drive vehicles, install chains on the front wheels; for rear-wheel drive or four-wheel drive vehicles, install chains on all four wheels. The installation method for automotive snow chains is as follows: 1. Lay the snow chain flat and centered in front of the tire; 2. Drive the vehicle forward half the length of the snow chain so that the tire's contact point is at the center of the chain; 3. Fasten the hooks on the inner side of the tire, then fasten the hooks on the outer side of the tire; 4. Continue moving the vehicle forward to adjust the connection points under load during installation, then secure the snow chains firmly.

What is the ACC switch?

ACC in automobiles stands for Adaptive Cruise Control. The ACC button is the switch for turning the vehicle's adaptive cruise control system on and off. Currently, there are mainly two types of cruise control systems in vehicles: one is ACC adaptive cruise control, and the other is conventional cruise control. The ACC adaptive cruise control system primarily includes functions such as speed adjustment, following the vehicle ahead, active braking, lane keeping, and lane departure warning and correction. Conventional cruise control only has the speed-setting function. Speed adjustment function: The driver sets a specific speed. Given the complex and varied traffic conditions on the road, it is often difficult for a vehicle to maintain a constant speed smoothly. ACC adaptive cruise control has the capability to decelerate and accelerate according to road conditions, which is the most distinctive feature differentiating it from conventional cruise control. Following the vehicle ahead function: This function ensures the distance between our vehicle and the one ahead. The driver can adjust the following distance to maintain a safe gap from the vehicle in front. Active braking function: When the vehicle is in a dangerous or near-dangerous situation, it can actively brake to a stop. Currently, this function's recognition range is limited to hazards directly ahead, with no accurate identification for side or rear hazards. Lane keeping function: The lane keeping function reduces driver fatigue by keeping the vehicle within the lane on roads with clear lane markings. The emergence of this function also marks the implementation of Level 2 driving assistance. Automatic speed adjustment frees the driver's feet, while the lane keeping function, under specific conditions, frees the driver's hands. Key switch function: ACC on the key switch allows the use of the vehicle's auxiliary electrical devices when the engine is off. Independent steering wheel button function: The independent ACC button on the steering wheel is the control switch for the cruise control. Difference between ACC and ON: Typically, when the vehicle is parked and the engine is off, the key is in the LOCK position, disconnecting the vehicle's circuits and cutting power to the entire vehicle, with the steering wheel locked. When the key is in the ACC position, some electrical devices in the vehicle, such as the radio and audio system, are powered, but other components of the vehicle remain without power.

Why do driving schools hold onto ID cards during registration?

Driving schools require holding onto ID cards during registration because they need the ID to process the student's driving record file. The vehicle management office also needs to verify the ID card, and it will be returned after the application is successfully processed. Tips for the Theory Test (Subject 1): During the exam, read the questions carefully and choose answers cautiously, as you cannot modify your selection once clicked. If unsure about a question, skip it and move on to the next one—there is ample time. However, make sure to review all questions at the end to avoid missing any. Tips for the Practical Test (Subject 2): Before starting, clean both side mirrors and window frames from outside the car. Adjust the mirrors and seat properly once inside, and ensure the seat is securely fixed. Always remember to fasten your seatbelt. For the reverse parking test, try to choose the parking spot at the very back. Tips for the Road Test (Subject 3): Avoid changing multiple lanes consecutively. Roads usually have several lanes, and after starting the car, you'll need to accelerate and change lanes. When changing lanes, do so one lane at a time—never switch across multiple lanes at once. Tips for the Safety Test (Subject 4): Follow exam hall rules, manage your time well to prevent missing questions, and always bring your ID card. Other materials should comply with exam hall regulations. Sit upright to ensure your face is captured by the camera. Answer questions carefully—once you move to the next question, you cannot go back. If you answer 5 questions incorrectly, the system will automatically notify you of failure, and you will need to retake the test.
