Hot weather does affect refueling. Here are some extended details: 1. Do not fill the tank completely: In summer, avoid filling the tank to the brim. If the tank is overfilled, the high temperatures can cause the gasoline to expand due to thermal expansion. When the car starts and moves, the gasoline will slosh around, leading to rapid evaporation in both gaseous and liquid forms. 2. Do not leave the tank empty for too long: While driving, always monitor the fuel gauge. When the gauge shows only a quarter of the tank remaining, it's time to refuel. It's best to refuel when the fuel light comes on. Leaving the tank empty for too long can cause a significant temperature difference between the inside and outside, leading to moisture buildup inside the tank. This can corrode the tank, degrade fuel quality, and increase the engine's workload.

Is it okay to drive at 120 km/h during the break-in period of a new Audi?

The break-in period is best around 00 days. Here are some precautions for breaking in a new car: Warm up before starting: Before starting the car, turn the key to the second position and wait 5-10 seconds before ignition. This is because the fuel pump starts working when the key is turned, adjusting oil pressure and fuel injection. Waiting a few seconds before starting benefits both the motor and engine. Avoid long-distance driving: Driving long distances in a new car increases continuous engine operation time, which can accelerate wear on mechanical parts. Initial maintenance: During the break-in period, frequently check engine oil, coolant, and battery electrolyte levels, and top them up immediately if low. After reaching a certain mileage, promptly visit a service center for vehicle inspection and maintenance, including oil and filter changes, and a comprehensive check of the chassis system. Generally, an oil change is needed after driving about 1,500 kilometers.

Is it normal for BMW X1 headlights to fog up?

Fogging is a normal phenomenon. Here are the relevant explanations: Reasons: BMW headlights adopt a non-sealed design for heat dissipation. There is an air intake hole and an exhaust hole on the headlight, which are used to balance the air temperature inside the headlight. The exhaust hole discharges hot air, while the air intake hole draws in cold air from outside. When the outside air is humid (such as during rainy or snowy weather), the air drawn in will contain relatively high moisture. After the headlights are turned off, the temperature inside the headlight decreases, and the drawn-in air condenses into fog. Brightness inspection: After driving 50,000 kilometers or more than two years, it is necessary to promptly inspect the brightness of the headlights. After a period of use, due to oxidation, power loss, and other reasons, the brightness of the headlights will be lower than the original level and will continue to decrease with prolonged use.

What is the appropriate pressure for car air conditioning refrigerant charging?

Car air conditioning refrigerant charging pressure: High pressure 1.3-1.7MPA; Low pressure 0.1-0.25MPA. The following are some introductions about air conditioning refrigerant charging pressure: 1. If the pressure is higher or lower than the above range, it indicates abnormal expansion valve adjustment. Compressor problems are not included in this category. 2. When measuring the pressure of the air conditioning system, the engine should be idling, and the measurement should be taken at an ambient temperature of 35℃. 3. When the engine throttle is increased, the measured low pressure should decrease with the engine speed. The faster the speed, the more the pressure drops, which indicates good compressor performance. Otherwise, it indicates a compressor failure.

Can the Kawasaki H2R be ridden on public roads?

The Kawasaki H2R cannot be ridden on public roads. As a professional track-level motorcycle, the Kawasaki H2R lacks rearview mirrors, headlights, and a license plate holder. Such designs do not comply with Chinese legal requirements, making it ineligible for registration. Below are the conditions for motorcycles to be legally ridden on public roads: Possession of a vehicle license and driver's license: The motorcycle must have a vehicle license. Motorcycles are classified as motor vehicles, and the vehicle license serves as valid proof that the vehicle can legally operate on public roads. Therefore, a vehicle license is an essential requirement for legal road use. Additionally, to legally operate a motor vehicle, the driver must possess a driver's license that matches the motorcycle's vehicle type. Only with this can the driver legally ride the motorcycle on public roads. Wearing protective gear: The driver must wear protective equipment, meaning the driver must wear a helmet while riding the motorcycle. There are also restrictions on road usage, as some areas do not permit motorcycles on public roads.
