Should the RAV4 use 92 or 95 octane gasoline?

[LeCarson]

Both 92 and 95 octane gasoline can be used for the RAV4. The selection method and basis are introduced as follows: Gasoline selection method: The difference between 92 and 95 octane gasoline is not significant, primarily in their octane ratings. This results in different anti-knock properties, and the choice should be based on the engine's compression ratio. You can refer to the compression ratio specified in the vehicle's manual, and manufacturers usually indicate the recommended gasoline grade in the manual. Gasoline selection basis: Compact cars generally do not have very high engine requirements, with compression ratios ranging between 8.6 and 9.9. Mid-size cars have compression ratios between 10 and 11.5. For engines with compression ratios exceeding 11.5, higher-octane gasoline may be considered—these engines are typically found in luxury-brand vehicles and deliver strong performance. Engines with compression ratios between 8.6 and 9.8 are suitable for 92 octane gasoline, while those between 10 and 11.5 are suitable for 95 octane gasoline.
