Will using 95 octane fuel instead of 92 damage the car?

[SanAdriana]

Using 95 octane fuel occasionally in a car designed for 92 octane will not cause damage, but long-term use can be harmful. Here are the specific reasons: 1. Switching from 92 to 95 octane means using a higher-grade fuel than recommended. In this case, the engine's compression ratio is insufficient, leading to incomplete combustion, sluggish acceleration, and delayed ignition. 2. Blindly using higher-octane fuel not only results in poor acceleration but also fails to utilize its high anti-knock properties, leading to unnecessary expenses. 3. The engine's compression ratio, ignition timing, and other parameters are preset by the manufacturer, and the most suitable fuel is the one recommended by the automaker.
