Audi A4L generally requires 4.5L of oil. Refer to the vehicle's manual for the recommended oil type. The oil model is usually 5W40. The selection of engine oil should be based on the manufacturer's manual requirements to determine the appropriate quality grade or higher. Here are the relevant details: Precautions: When selecting engine oil, seasonal changes should also be considered because the viscosity of the oil changes with temperature. In winter, the viscosity becomes thicker, while in summer, it becomes thinner. Therefore, in extremely hot regions, it is advisable to choose oil with slightly higher viscosity. In colder seasons, thinner oil can be used. Oil usage: The Audi A4L engine is designed for high performance, and during operation, the internal temperature of the engine is very high. Using 5W40 high-viscosity oil can better protect the internal components of the engine and more effectively reduce the engine's internal temperature.

What Does the ET Value of a Tire Mean?

Tire ET value refers to the Offset value, which is the deviation between the mounting surface of the wheel hub and the centerline of the rim, measured in millimeters. It can be positive, zero, or negative. A positive Offset value means the mounting surface is towards the outer side of the wheel, while a negative value means it is towards the inner side of the rim. Changing the ET value of the rim alters the track width of the vehicle, which is the distance between the centerlines of the tires. Simply increasing the size of the rim and tire without changing the ET value does not affect the track width. Using a rim with a smaller positive ET value will widen the track width, thereby reducing the shift in the vehicle's center of gravity during cornering and improving the cornering speed limit.

Can Halogen Car Lights Be Replaced with LED Lights?

Car halogen lights can be replaced with LED lights, but it is important to note that the focal points of the original halogen light reflectors and lenses differ from those of LED lights. The light beams formed by LED lights may be uneven, and depending on the quality of the product, LED lights with poor heat dissipation and constant current effects may have relatively inferior lighting performance. Additionally, improper handling of heat dissipation can significantly impact the vehicle itself. Halogen bulbs, also known as tungsten halogen bulbs or quartz bulbs, are a variant of incandescent lamps. Their principle involves injecting halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament reacts chemically with the halogen, and the cooled tungsten re-solidifies on the filament, forming a balanced cycle that prevents premature filament breakage. Halogen bulbs have a longer lifespan compared to incandescent bulbs.

Can a C2 License Drive Manual Transmission Vehicles?

C2 license holders are not permitted to drive manual transmission vehicles. The authorized vehicle types for a C2 license are small and micro automatic transmission passenger cars, as well as light and micro automatic transmission cargo vehicles. If a C2 license holder is caught driving a manual transmission vehicle, they will be penalized as driving without a license. According to relevant regulations, operating a motor vehicle requires obtaining a motor vehicle driving license in accordance with the law. The full name of the driving license is the motor vehicle driving license, also known as a 'driver's license,' which is a certificate required by law for individuals to operate motor vehicles. Driving a motor vehicle requires certain driving skills, and without these skills, driving a motor vehicle recklessly could lead to traffic accidents. Generally, individuals cannot drive on the road without a license.

Why is there water coming out of the car's exhaust pipe?

Water coming out of the car's exhaust pipe is condensation, which is a normal phenomenon. When water flows from the exhaust pipe, the external temperature must be relatively low, indicating that the fuel is being fully combusted. When gasoline burns completely, it produces only carbon dioxide and water. The temperature inside the cylinder during combustion ranges from 400 to 800 degrees Celsius. Under high temperatures, water is vaporized. In cold weather, the vaporized water is condensed by the exhaust pipe into water mist, which then gathers into droplets and flows out. The car exhaust, also known as the car exhaust pipe hose, is installed between the engine exhaust manifold and the muffler. It allows the entire exhaust system to have flexible connections, thereby reducing vibration and noise, and extending the lifespan of the exhaust muffler system.
