Why does Volkswagen require 95-octane gasoline?

[McJordan]

Volkswagen requires 95-octane gasoline for the following reasons: 1. Volkswagen vehicles use 95-octane gasoline because most of its models are equipped with turbocharged engines. During high-speed driving, the turbocharger operates more powerfully, which imposes strict requirements on gasoline. 95-octane gasoline has better anti-knock properties compared to 92-octane gasoline. If German cars use 92-octane gasoline for an extended period, it can lead to engine knocking, which is very dangerous. 2. The difference in gasoline grades lies in the octane rating of the additives (octane rating affects anti-knock performance). The higher the gasoline grade, the higher the octane rating, and the better the anti-knock performance, making it more suitable for high-compression engines. However, this is not absolute, as it also depends on the manufacturer's technology, tuning, and the engine's inherent characteristics.
