Will using 92-octane gasoline in a car designated for 95-octane have any impact?

Using 92-octane gasoline in a car designated for 95-octane will have an impact. If 92-octane gasoline is used for an extended period, it can cause certain damage to the car's engine, and in severe cases, may even lead to engine failure, rendering it beyond repair. The reason cars specify a particular octane rating is due to differences in engine performance. Cars that require higher-octane gasoline generally have engines with better anti-knock properties. If an engine is designed for 95-octane fuel, it must use 95-octane gasoline. Prolonged use of a lower-octane fuel can affect the car's ignition system, fuel injectors, and spark plugs, potentially leading to issues such as engine shaking, bent valves, or damage to the valve cover. There is no difference in fuel quality between 95-octane and 92-octane gasoline. Typically, high-compression engines require higher-octane fuel. 92-octane gasoline has an octane rating of 92, while 95-octane gasoline has an octane rating of 95. The chemical compositions of these two fuel types are quite similar, but 95-octane gasoline offers higher fuel efficiency and provides more robust power for the vehicle. Generally, naturally aspirated cars use 92-octane fuel, while turbocharged cars require 95-octane fuel.
