What grade of gasoline should the Kia K4 use?

[HoldenMarie]

Kia K4 recommends using 92-octane gasoline, with the following details: 1. Each engine has a different compression ratio. The higher the compression ratio, the higher the requirement for gasoline stability. 2. Some automakers, to adapt to domestic gasoline quality, have to reduce power output or use anti-knock technology to lower the required gasoline grade. 3. The higher the gasoline grade, the better its stability, and the relatively higher the price. The recommended gasoline grade is usually indicated on the fuel tank cap. It is sufficient to refuel according to the recommendation, and there is no need to use a higher grade of gasoline.
