Should the Equinox use 92 or 95 octane gasoline?

[GiselleAnn]

The Equinox is equipped with two turbocharged engines across its lineup, so it is recommended that owners use 95 octane gasoline. Gasolines with different octane ratings have varying levels of octane; the higher the octane rating, the higher the octane level, and the better the anti-knock performance of the gasoline. If the octane rating of the gasoline is too low, its anti-knock performance will be poor, which can lead to engine knocking during operation. Knocking is an abnormal combustion phenomenon in the engine. When the piston is in the compression stroke, it moves upward to compress the air-fuel mixture, at which point the pressure and temperature of the mixture increase. If the gasoline's anti-knock properties are inadequate, the air-fuel mixture may ignite before the spark plug fires.
