What Kind of Oil is Best for Turbocharged Engines?

Turbocharged engines are best suited for full synthetic oil. Here is an introduction to full synthetic oil: Full synthetic oil is a man-made lubricant that undergoes chemical decomposition of various natural substances during production, followed by synthesis with other materials to produce the final synthetic oil. It offers more stable chemical properties, better fluidity, and lower resistance, providing optimal engine protection while reducing fuel consumption. When selecting oil, pay attention to two key indicators: SAE and API. SAE indicates the oil's viscosity grade, while API represents the oil's quality level. In the API quality classification (e.g., "SN" or "CG"): "S" denotes oil for gasoline engines, and "C" denotes oil for diesel engines. If both "S" and "C" are present, the oil is suitable for both gasoline and diesel engines. The letters following "S" or "C" (e.g., from "SA" to "SN") indicate progressively better performance with each increment. Currently, the highest API quality grade is SN.

What Causes Abnormal Noises from Car Window Glass While Driving?

Abnormal noises from car window glass while driving may be caused by the following reasons: 1. Aging of the glass sealing strip leading to noise from the window glass. Solution: If it's a newly purchased car with vibrating glass sounds, there's no need to replace the sealing strip. Simply apply electric lubricating oil evenly on the strip and repeatedly raise and lower the glass a few times. If the sealing strip is severely aged, it's best to replace it directly. 2. Dust and particles can easily enter the gaps of the window glass sealing strip in the glass track during window operation, which can cause abnormal vibrations and noises. Solution: Use professional tools to promptly clean out debris from the glass track. 3. Loose fastening screws or misaligned parts inside the car dashboard can cause the window glass to vibrate and produce abnormal noises. Solution: This issue may be related to improper screw tightening and installation positioning during the manufacturer's assembly. To completely eliminate the fault, the dashboard needs to be removed for inspection and repair.

What are the causes of engine stalling at idle?

Engine stalling at idle can be caused by the following reasons and solutions: Causes of engine stalling at idle: Severe carbon buildup in the engine; Dirty throttle body or carbon deposits in the fuel injectors; Faulty spark plugs, high-voltage wires, or ignition coils leading to poor ignition system performance; Unstable oil pressure, insufficient fuel supply pressure from the fuel pump, or incorrect readings from the intake pressure sensor; Clogged fuel lines causing insufficient fuel supply; Aging engine components. Solutions for engine stalling at idle: Regularly clean the throttle body; Periodically clean the fuel injectors to prevent carbon buildup; Replace spark plugs; Use gasoline from reputable gas stations. Engine stalling at idle refers to the situation where the engine starts and runs well from low to high speeds, but stalls immediately when the accelerator pedal is released or becomes unstable and then stalls.

How to Turn Off the Start-Stop Function in Audi?

There are two methods to disable the Audi automatic start-stop function: 1. When starting the vehicle, enter the car and start it. The Audi automatic start-stop function is enabled by default. Locate the automatic start-stop switch near the center console and turn it off. After turning it off, the dashboard will indicate that the automatic start-stop function is unavailable. However, if you restart the ignition switch, you will need to repeat this step to ensure the system remains off. 2. Use a specialized diagnostic tool. Insert the diagnostic tool into the vehicle's OBD port and establish communication with the vehicle. Navigate to address code 09 for the central electrical equipment control unit. Find the access function and enter "20113" to confirm. Input channel number "34", read and record the original value, add "30" to the original value, and click save.
