Can the Mercedes-Benz GLA use 92 octane gasoline?

[DelMaximus]

Mercedes-Benz GLA cannot use 92 octane gasoline. Generally, such high-performance coupes require 95 octane gasoline. Introduction to gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. Key characteristics of gasoline: In the engine cylinder, gasoline must rapidly vaporize and form a uniform combustible mixture with air, which is mainly determined by the gasoline's own volatility. The main indicators reflecting volatility are distillation range and saturated vapor pressure. The property that measures whether fuel is prone to knocking is called anti-knock quality, which is represented by the octane number (RON). The higher the octane number of gasoline, the better its anti-knock quality. For the same hydrocarbon family, smaller carbon numbers result in better anti-knock quality and higher octane numbers.
