What is the fuel consumption of the Classic Sylphy?

The comprehensive fuel consumption of the Classic Sylphy is 5.2-6.1L/100km. Currently, there are three models of the Classic Sylphy available for sale: the CVT Luxury Edition and CVT Comfort Edition, both with a comprehensive fuel consumption of 5.2L/100km. The Manual Comfort Edition has a comprehensive fuel consumption of 6.1L/100km. The above figures are based on the NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than these values, ranging from 6.8-8.0L/100km. Specific factors affecting car fuel consumption are as follows: Car weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of approximately 7.5 liters (calculated under full load conditions), while an SUV weighing around 1.5 tons consumes about 8.5 liters. Different weights lead to varying fuel consumption. Drag coefficient: Higher drag increases fuel consumption during driving. Cars with better aerodynamics have lower drag coefficients, resulting in lower fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point. Maintaining the car's speed within this torque output range significantly reduces fuel consumption. Generally, small-displacement cars achieve this at around 70 km/h, while larger-displacement cars do so at about 100 km/h. Staying within this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before stopping at traffic lights can increase fuel consumption.

What is the difference between 0W-20 and 0W-40?

The difference between 0W20 and 0W40 lies in their base viscosity and high-temperature shear resistance, as detailed below: Both 0W20 and 0W40 start with 0W, indicating they share the same low-temperature viscosity. The key distinction is the numbers following the W—20 and 40—which represent the oil's kinematic viscosity at 100°C. A 20-grade oil has a kinematic viscosity of 8-9 at 100°C, while a 40-grade oil ranges between 12.5-15. Higher numbers indicate thicker oil films at high temperatures and stronger resistance to shear. The high-temperature shear index for 20-grade oil typically does not exceed 2.9 mPa·s, whereas 40-grade oil maintains a shear index above 3.5 mPa·s. Additionally, 0W40 exhibits poorer high-temperature fluidity compared to 0W20. Oil viscosity changes with temperature, making it crucial to consider performance under both low and high temperatures. For example, in 5W-30, the first number denotes low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. A smaller number indicates better low-temperature fluidity, ensuring smoother cold starts for the engine. The second number represents the oil's kinematic viscosity at 100°C, with higher values indicating better viscosity retention and lubrication performance at high temperatures. Better low-temperature fluidity facilitates smoother cold starts and enhanced engine protection. Different engine designs require either 20-grade or 40-grade oil. 20-grade oil is commonly used in newer Japanese, Korean, and American models, while 40-grade oil is preferred for German, high-displacement, and high-performance vehicles. For full synthetic oil, the recommended replacement interval is one year or 10,000 kilometers. Semi-synthetic oil requires more frequent changes—around 7,000 kilometers or every six months. When selecting engine oil, keep the following in mind: Choose oil based on the engine's requirements. Avoid using overly advanced oil for less demanding engines or lower-grade oil for high-performance engines. Opt for multi-grade oil whenever possible. Multi-grade oils are economical, long-lasting, and efficient, offering superior engine protection. Due to their properties, they may darken prematurely or exhibit lower oil pressure compared to conventional oils—both are normal. Since oil significantly impacts engine performance and lifespan, always adhere to the vehicle's manual for the specified series, service grade, and viscosity grade. The manufacturer-recommended oil considers engine performance and regional climate conditions, providing a reliable guideline with a substantial safety margin.

What to Pay Attention to When Sleeping in a Parked Car with Air Conditioning On

When sleeping in a parked car with the air conditioning on, pay attention to the following: 1. Avoid sleeping in poorly ventilated parking lots. If you must sleep in the car, ensure good air circulation. In environments with poor ventilation, if the car is left idling, carbon monoxide produced during idling can accumulate and cannot be dispersed. If it enters the car, it may lead to carbon monoxide poisoning. 2. Do not use the air conditioning in recirculation mode. The external air circulation mode draws air from outside the car, which is then cooled or heated by the air conditioning before entering the car. In contrast, the recirculation mode cuts off the exchange with outside air, causing the air inside the car to circulate continuously. 3. Maintain air exchange between the inside and outside of the car. To ensure ventilation, besides keeping the air conditioning in external air circulation mode, you can also slightly open the windows while sleeping. This way, it won’t significantly affect the air conditioning effect inside the car while still allowing air exchange between the inside and outside.

What does the traffic violation code 12070 mean?

The traffic violation code 12070 means: The driver of a motorcycle did not wear a safety helmet as required. According to the relevant provisions of the "Road Traffic Safety Law of the People's Republic of China", the penalty includes: Demerit points (deduction): 2 points; Fine amount: 50 yuan; Other penalties: None. Traffic violation codes consist of four to five digits, classified according to the general principles of the traffic law. The order from left to right is: the first digit is the behavior classification code, the second digit is the demerit point classification code, the third and fourth digits are the sequential code, and the fifth digit is the item number. First digit: Behavior classification code, indicating the category of the violation in the Road Traffic Law; Second digit: Demerit point classification code, indicating the category of demerit points for the traffic violation; Third, fourth, and fifth digits: Sequential code, indicating the order of the violation within the same behavior classification. For example: 13035—"1" indicates a motor vehicle violation, the second digit "3" indicates a deduction of 3 points, and "035" indicates the fifth item of the third violation in the 3-point deduction category. Behavior classification code violation descriptions: Codes starting with "1" indicate motor vehicle violations, e.g., 1003; Codes starting with "2" indicate non-motor vehicle violations, e.g., 2002; Codes starting with "3" indicate pedestrian or passenger violations, e.g., 3030; Codes starting with "4" indicate highway violations, e.g., 4002; Codes starting with "5" indicate other regulations, e.g., 5005; Codes starting with "7" indicate implementation rules of provinces, autonomous regions, or municipalities, e.g., 7008; Codes starting with "8" indicate local regulations of cities (prefectures, autonomous prefectures, or leagues), e.g., 8606. There are four common ways to check motor vehicle violations: Visit the office halls of traffic branches or teams in various districts and counties to inquire through touch-screen terminals; Log in to the external service website of the local Public Security Bureau's Traffic Management Bureau, find the vehicle violation inquiry section, enter the license plate number and vehicle engine number, and click to inquire; Call the inquiry hotline (area code + 114); Use the Traffic Management 12123 app client (V2.8.1B437 for iOS 15+ or V2.8.1B274 for Android 12+) to inquire. The violation of not wearing a safety helmet while driving a motorcycle can be handled through this Traffic Management app client.
