What Type of Engine Oil Should Be Used in Northeast China During Winter?

What are the maintenance items for 7500 kilometers?

For a car that has traveled 7,500 kilometers, general maintenance items include oil change, filter replacement, air filter replacement, brake pad replacement, and coolant replacement. Oil and filter replacement: Whether it's a new or used car, a regular maintenance check is required every 7,500 kilometers, and changing the oil and oil filter is one of the essential items. If the oil and filter are not replaced for a long time, the oil may deteriorate, which can easily cause severe damage to the engine and other components. Air filter replacement: The air filter is also a critical safety checkpoint for the car, effectively preventing dust from entering the cylinder. If the car is frequently driven in areas with a lot of dust, the air filter replacement interval should be shortened. Brake pad replacement: After long-distance driving, the brake pads will experience corresponding wear. Therefore, it is necessary to check the wear level of the brake pads and determine whether replacement is required. Coolant replacement: Coolant protects the car's engine, ensuring more even heat dissipation. During maintenance, it is necessary to wait for the car to cool down before replacing it with new, qualified coolant.

Is Safety Inspection the Same as Maintenance?

Safety inspection is not maintenance. Safety Inspection: Vehicle safety inspection is a mandatory test for every car, equivalent to a physical examination for the vehicle, aimed at promptly eliminating potential safety hazards. Car Maintenance: Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as vehicle servicing.

Can You Still Drive at Over 70 Years Old?

You can still drive at over 70 years old because there is no age limit for driving C1 and C2 vehicles. However, drivers aged 70 and above must have their driver's license checked annually. Submission of physical condition certificate: Motor vehicle drivers aged 70 and above must submit a physical condition certificate once a year. Within 30 days after the end of the scoring cycle, they must submit a physical condition certificate issued by a county-level or higher medical institution or a military medical institution at the regimental level or above. For those applying for a small automatic transmission passenger vehicle for the disabled, a physical condition certificate issued by a specialized medical institution designated by the provincial health authority must be submitted. Drivers holding A1, A2, A3, B1, B2, N, or P licenses: After reaching the age of 60, they must go to the license issuing authority to exchange their license for a small motor vehicle driver's license. After switching to a C1 license, drivers must still undergo an annual review of their driver's license (d1) and submit a physical condition certificate upon reaching the age of 70.

How much over the speed limit will result in penalty points?

Exceeding the speed limit by 10% will result in penalty points. Exceeding the speed limit by 10% but less than 20% will result in 3 penalty points; exceeding by 20% but less than 50% will result in 6 penalty points; exceeding by 50% or more will result in 12 penalty points. Upcoming new regulations: According to the new announcement from the Ministry of Public Security, new traffic regulations will take effect on April 1, 2022. Under the new regulations, exceeding the speed limit by less than 20% will not result in penalty points; exceeding by 20%-50% will result in 6 penalty points on highways and urban expressways, and 3 penalty points on regular roads; exceeding by 50% or more will result in 12 penalty points on highways and urban expressways, and 6 penalty points on regular roads. Dangers of speeding: When speeding, vehicles are often in a state of accelerating to follow or overtake other vehicles. Due to the close following distance, the driver's view is inevitably obstructed, leading to unclear observation and inaccurate judgment of the road ahead, resulting in high levels of blind risk. Moreover, speeding severely impairs the driver's vision—the higher the speed, the worse the vision becomes, greatly increasing the likelihood of accidents.

How to Detect Refrigerant Leakage in Car Air Conditioning?

There are several methods to detect refrigerant leakage: 1. Visual Inspection: This is the simplest and most primitive method, but also the least effective. Very minor leaks may not be detectable at all. 2. Electronic Leak Detection: This is a new and popular method in recent years. A detection probe is moved around potential leakage areas, and an alarm from the device indicates a significant leak. However, electronic detection can be affected by external factors like gasoline, exhaust fumes, or odors, which may lead to incorrect detection. 3. Water Immersion Test: Commonly used for components like compressors, condensers, and evaporators. The method involves filling these parts with compressed air and then immersing them in warm water (around 50 degrees Celsius) to observe for bubbles. Warm water is used to reduce surface tension, as colder water has higher surface tension, making minor leaks harder to detect. 4. Fluorescent Leak Detection: This method uses fluorescent dye that emits bright yellow-green light under UV/blue light. The dye is added to the air conditioning system in a specific ratio. After running the system, a UV lamp and special glasses are used to detect leaks, which appear as yellow fluorescence. The advantages of fluorescent detection include accurate localization, visible leakage points, simplicity, portability, and low repair costs.
