Can a car that uses 92 octane fuel use 95 octane fuel? The octane rating of gasoline recommended by car manufacturers is based on the compression ratio of the engine design, and you should choose the appropriate octane rating according to the recommendation. Mixing different octane ratings of gasoline will not cause a chemical reaction, as different octane ratings have different octane values. The higher the octane rating, the higher the octane value, and the better the stability of the gasoline. Many car engines require the use of high-octane gasoline to prevent engine knocking. Knocking is an abnormal combustion phenomenon in the engine, which occurs during the compression stroke. When the engine is in the compression stroke, both the intake and exhaust valves are closed, and the piston moves upward to compress the combustible mixture.
