How Many Years Are New Cars Exempt from Inspection in Shanghai?

New cars are exempt from inspection for 6 years. Below are the relevant details: 1. Exemption conditions: The motor vehicle must be a non-commercial vehicle; the approved seating capacity is 6 or fewer. Starting from November 20, 2020, non-commercial mini and small passenger vehicles with 7 to 9 seats are included in the exemption scope. Vehicle types specified on the driving license: sedan (mini, small, medium, large), mini ordinary passenger vehicle, mini off-road passenger vehicle, small ordinary passenger vehicle, small off-road passenger vehicle, small special passenger vehicle. 2. Relevant regulations on motor vehicle annual inspection: Commercial passenger vehicles must be inspected once a year within 5 years; after 5 years, once every 6 months; trucks and large and medium non-commercial passenger vehicles must be inspected once a year within 10 years; after 10 years, once every 6 months.

Can 98 and 95 be mixed?

95 gasoline and 98 gasoline can occasionally be mixed, but it is not recommended to mix them for a long time. The following is a specific introduction about gasoline: Long-term mixing of gasoline can cause engine knocking. Gasoline is a mixture. The gasoline grade we usually come into contact with refers to the anti-knock index of gasoline (i.e., the octane number). Strictly speaking, 95 gasoline and 98 gasoline cannot be mixed. However, their chemical composition and other aspects are relatively similar, with strong anti-knock performance. To ensure vehicle safety, they should still be used separately. In some areas, there is also low-grade 90 gasoline. If it is mixed with high-grade gasoline, it will cause knocking, insufficient power, and other phenomena, affect the service life of spark plugs, and bring more exhaust pollution. The density of 98 gasoline is generally above 0.74. 98 gasoline is gasoline whose octane number is equal to a mixture of 98% isooctane and 2% n-heptane. The advantage of 98 gasoline is "two highs and two lows", that is, higher anti-knock performance and power performance, and lower harmful substances and exhaust pollution in gasoline. 95 gasoline has strong anti-knock performance and will not be compressed and ignited under high pressure, ensuring that the engine is at the optimal ignition advance angle, and the power output is not affected. The gasoline grade also represents the anti-knock performance of the fuel. The larger the grade, the better the anti-knock performance. Anti-knock performance refers to the ability of gasoline to resist knocking when burning in the engine. It is the primary indicator of gasoline combustion performance. Knocking is caused by abnormal combustion of gasoline in the engine. The octane number is the target of gasoline anti-knock performance. The higher the octane number, the stronger the anti-knock performance, and the higher the compression ratio, the higher the pressure in the combustion chamber. If gasoline with low anti-knock performance is used, knocking is more likely to occur.

How many points are deducted for occupying the emergency lane on urban expressways?

Occupying the emergency lane on urban expressways results in a deduction of 6 points. Below is a detailed introduction regarding the occupation of emergency lanes: 1. Highway lanes: For non-commercial vehicles parked in highway lanes, a one-time deduction of 6 points is applied. 2. Highways or urban expressways: Driving a motor vehicle and illegally occupying the emergency lane on highways or urban expressways results in a one-time deduction of 6 points. 3. Lane borrowing during slow traffic: When encountering slow or stationary traffic ahead, borrowing a lane to overtake or occupying the opposite lane or cutting into waiting traffic results in a one-time deduction of 2 points. Additionally, illegal parking of commercial passenger vehicles in the emergency lane results in a deduction of 12 points.

Why does the car make two clicking sounds intermittently when the air conditioner is on?

This is a normal phenomenon, which is the sound of the compressor engaging. Below is a relevant introduction about the car air conditioning system: 1. Introduction to car air conditioning: The car air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. It is used to regulate the temperature and humidity inside the car, providing a comfortable environment for the driver. 2. Working principle: When the compressor is working, it sucks in low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser and liquefies, turning into a liquid.

What materials are required to apply for an inspection exemption label?

You need to provide the vehicle's driving license, the ID card or a copy of the vehicle owner, and the compulsory traffic insurance policy of the vehicle to obtain the inspection exemption label. When collecting the label, the vehicle must not have any traffic violations or unresolved traffic accidents. Related information: 1. Methods for handling vehicle inspection exemption: There are two methods: processing through the mobile app "Traffic Management 12123" or directly at the vehicle management office or traffic management department of the public security authority. The vehicle does not need to be present during the process, and it can also be handled by someone else on behalf of the owner. During the process, any traffic violations must be resolved, and there should be no unresolved traffic accidents. 2. Conditions for vehicle inspection exemption: The vehicle must be a non-operational small or micro passenger car with no more than nine seats to qualify for inspection exemption, excluding minivans. It is important to correctly understand inspection exemption; it does not mean exemption from the process. The vehicle still needs to undergo the normal annual inspection procedures to be used legally.

Where is the tire pressure reset button for the 2018 Golf?

The tire pressure reset button for the 2018 Golf is the set button located below the left side of the steering wheel. Related details are as follows: 1. Self-calibration: The Golf's tire pressure elimination button is the tire pressure monitoring indicator button located on the lower part of the central sub-instrument panel. The calibration of the tire pressure monitoring indicator is divided into types A and B. During normal driving, the tire pressure monitoring indicator can self-calibrate based on the installed tires and the tire pressure adjusted by the driver, storing and monitoring the calibration values after long-distance driving at different speeds. 2. Monitoring indication: For the Golf's calibration of the tire pressure monitoring indicator (type B), it is necessary to recalibrate the tire pressure monitoring indicator after changing the tire pressure or replacing one or more wheels. The tire pressure monitoring indicator must also be recalibrated after wheel rotation (e.g., front and rear wheel rotation).
