Should I replace the entire wiper or just the wiper blade?

Generally, it's recommended to replace just the wiper blade. Here's some information about wipers: 1. Structure: The wiper frame is very sturdy. Even if the replacement frame is of high quality, it still can't match the original frame from the vehicle. If your wiper fails, you don't need to replace the entire wiper - just replacing the rubber blade will achieve the same effect as replacing the whole wiper. 2. Proper usage tips: Temperature changes, gravel, dust, etc. can all shorten the lifespan of wiper blades. Regularly cleaning dirt from the windshield and wiper blades, especially after rain, can reduce unnecessary wear and extend the life of the wiper blades.

What type of gasoline should be used for Audi A4L?

Audi A4L requires the use of 95-octane or higher gasoline. Below is an extended introduction about gasoline: Composition of 95-octane gasoline: 95-octane gasoline consists of 95% isooctane and 5% n-heptane. High-compression engines should use high-octane gasoline. If low-octane gasoline is used in a high-compression engine, it may cause abnormal combustion, resulting in knocking, increased fuel consumption, and reduced driving power. Refueling precautions: High-compression engines can use low-octane gasoline, but one should not blindly choose gasoline based solely on compression ratio. Instead, the manufacturer's recommended gasoline grade should be followed.
