Whether to choose 0w20 or 5w20 engine oil for Corolla mainly depends on the vehicle's usage environment: 1. If you are in the northern region with colder weather, 0w20 engine oil is recommended. 0w20 oil has better low-temperature fluidity and cold resistance than 5w20. 2. If you are in the milder climate of the southern region, 5w20 is completely sufficient. Here is some relevant information about engine oil: 1. The number before W represents the oil's cold resistance. For example, 0W oil will freeze at -35°C, while 5W oil will freeze at -30°C. 2. The low-viscosity grades of engine oil are 0W, 5W, 10W, 15W, 20W, and 25W. The smaller the number, the better the low-temperature cold start performance. The viscosity grades at 100°C are 20, 30, 40, 50, and 60, with higher numbers indicating higher viscosity.

Do I Need to Retake the Written Test When Switching from Manual to Automatic Transmission?

No. Here are the details: Reason: During the examination process for a C1 driver's license, you can switch to a C2 driver's license because the C1 license covers the C2 vehicle type. Since you have already passed the written test (Subject 1), you do not need to retake it after switching to a C2 license. You can apply to the driving school to change to a C2 license, and the school will handle the modification of the registered license type at the vehicle management office. Examination: Each subject can be taken once, and if you fail, you can retake it once. If you do not attend the retake or fail again, the examination process ends, and you must reschedule the test. However, for Subject 2 and Subject 3, the rescheduling must be done at least ten days later. If you fail the Subject 3 safety and civilized driving knowledge test, the passing scores for the road driving skills test remain valid.

How Many Kilometers Before Changing Antifreeze Normally?

Antifreeze is generally changed every two years, though some suggest 4-5 years or longer. Follow the owner's manual for guidance. If no specific interval is stated, determine the need for replacement based on the antifreeze's freezing point or condition. Antifreeze Replacement Intervals: For vehicles with prolonged operation, such as taxis, high-quality antifreeze should typically be replaced annually. For vehicles with shorter operation times, replacement every two years or every 30,000 kilometers is sufficient. To prevent excessive foaming, which reduces heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-life antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration/discoloration are observed in the antifreeze, replace it promptly and flush the system. How to Check for Low Antifreeze Levels: Monitor the antifreeze warning light on the dashboard. If illuminated, it likely indicates low antifreeze levels, though it could also signal excessively high cylinder temperatures. Inspect the antifreeze reservoir. If the level is below the minimum mark (MIN), do not continue driving; add antifreeze immediately. Check the water level markers on the antifreeze tank. The normal antifreeze level should be between the maximum and minimum marks. If it falls below the minimum mark, it indicates a deficiency.

Can the sunroof be canceled when ordering a car?

Yes. Here is the relevant introduction: Car sunroof: The car sunroof is not a mandatory configuration. Car owners can reasonably choose whether to have a sunroof based on their needs. Proper use of the sunroof can provide a fresher driving environment during the journey and assist in defogging in foggy weather. In summer, reasonable use of the sunroof can help lower the temperature inside the car in the shortest time. Leakage and dust accumulation: If the sunroof is used frequently, dust may accumulate in the gaps, making cleaning difficult. Additionally, if the sunroof's sealing is compromised, it may leak during rainy days, which is troublesome to handle and inconvenient for the car owner. Difficult maintenance: During use, the sunroof may produce abnormal noises due to assembly issues, affecting the driving experience. If the rubber seals around the sunroof age, it can also increase the car's maintenance costs. Safety hazards: Although car sunroofs may have anti-pinch functions, accidents can still occur. If objects fall from a height, they may break the sunroof, posing a threat to the safety of passengers. Therefore, consumers need to make a reasonable choice regarding the sunroof configuration.
