Is it necessary to use 95 octane gasoline for the Vezel?

[CarlosRose]

The minimum fuel grade required for the Vezel is 92 octane, so there is no need to use 95 octane gasoline. Using 92 octane gasoline is sufficient to meet the engine's operational requirements. Generally speaking, Japanese cars typically use engines that require 92 octane fuel, with only some turbocharged engines requiring higher-grade 95 octane gasoline. Definition of gasoline grades: Gasoline grades represent the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher grades are not necessarily better; the appropriate gasoline grade should be chosen based on the engine's compression ratio. Misconceptions about gasoline usage: Some people fall into the misconception of preferring higher-grade gasoline, and some even consider the gasoline grade as a standard for fuel purity and quality. This is a mistaken notion. In fact, the grade of gasoline only indicates the octane value and should never be confused with purity and quality.
