Will using 92-octane gasoline affect the Audi A3?

[DelAlaina]

Audi A3 using 92-octane gasoline will have an impact, as it will reduce power output. The Audi A3 should be filled with 95-octane gasoline. Correct method for selecting gasoline octane rating: Check the label inside the fuel tank cap. There is always a (recommended standard) sticker on the inside of the car's fuel tank cap, which is the most accurate and scientific standard calculated by engineers based on the engine's technical parameters. Hazards of using the wrong gasoline: If a high-compression engine uses low-octane gasoline, it will cause incomplete combustion, severe engine vibration, reduced power output, damage to engine components, increased fuel consumption, and poor driving performance. However, if a low-compression engine uses high-octane gasoline, it will result in delayed combustion, meaning the auto-ignition point is not reached at maximum compression, leading to incomplete combustion as well. This requires additional fuel injection to ensure power output, which not only offers no benefit to the engine but also increases fuel consumption.
