Should the Sagitar use 92 or 95 octane gasoline?

[LeDelaney]

The Sagitar 1.6L can use either 92 or 95 octane gasoline. However, for turbocharged engines with a compression ratio exceeding 10, such as the Sagitar 1.4T, while both 95 and 92 octane gasoline can be used, 95 octane is recommended for better engine protection. Below are the relevant details: 1. The difference between 95 and 92 octane gasoline: The main distinction lies in their anti-knock properties, determined by their iso-octane content. Generally, it's sufficient to follow the manufacturer's recommended gasoline type without necessarily opting for a higher octane rating. While the Sagitar uses standard 95 octane gasoline abroad, the engines have been optimized for the domestic market to accommodate local fuel quality conditions. 2. Gasoline selection criteria: The choice of gasoline is primarily related to the engine's compression ratio. Typically, 92 octane gasoline is suitable for gasoline-powered vehicles with a compression ratio between 8.6 and 9.9. 95 octane gasoline is appropriate for engines with a compression ratio between 10.0 and 11.5, while 98 octane gasoline is recommended for vehicles with a compression ratio above 11.6.
