Is it better to use 92 or 95 octane gasoline for the Fit?

[SanFinley]

The official recommendation for the Fit is to use 92 octane gasoline. The fuel cap of the Fit indicates that 92 or higher octane gasoline can be used, meaning both 92 and 95 octane are acceptable. Below are the differences between 92 and 95 octane gasoline: 1. Price difference: 92 octane gasoline is cheaper than 95 octane. Due to market competition and regional factors, prices vary among gas stations. For example, stations in city centers, which are in prime locations, generally have higher prices, while those in more remote areas like the outskirts tend to have lower prices. Regardless of price fluctuations, at the same gas station, 92 octane is always cheaper than 95 octane. 2. Octane rating difference: 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. 3. Performance and fuel efficiency difference: 95 octane gasoline has an advantage over 92 octane in terms of power and fuel efficiency because it has a higher isooctane content than 92 octane.
