Should the Cruze RS use 92 or 95 octane gasoline?

[DelSerenity]

The Cruze RS is designed to use 92 octane gasoline. Strictly speaking, there are certain differences between using 95 octane and 92 octane gasoline in the engine. Compared to 92 octane, 95 octane gasoline has a higher octane rating, which means better anti-knock performance for the engine. Here are some details about gasoline octane ratings: 1. The octane rating does not indicate the quality of the gasoline but rather the proportion of isooctane, which determines the anti-knock performance. 2. As long as the gasoline comes from a reputable gas station, the quality is guaranteed. Different engines have different compression ratios, which affect the pressure applied to the air-fuel mixture. 3. If a high-compression engine uses gasoline with lower anti-knock properties, it may cause knocking, and frequent knocking can damage the engine. 4. Using high-octane gasoline in a low-compression engine will not harm the engine.
