Is it better to use 92 or 95 octane fuel for the 10th-generation Civic?

[StEmily]

The 10th-generation Civic performs better with 95 octane fuel, as it offers superior power and anti-knock properties compared to 92 octane. The differences between 95 and 92 octane are as follows: 1. Price difference: 92 octane is cheaper than 95 octane. Due to market competition and regional factors, prices vary across gas stations. For example, stations in city centers generally charge higher prices due to their prime locations, while those in suburban or remote areas tend to have lower prices. Regardless of price fluctuations, 92 octane is always cheaper than 95 octane at the same station. 2. Octane rating difference: 92 octane contains 92% isooctane and 8% n-heptane, whereas 95 octane contains 95% isooctane and 5% n-heptane. 3. Performance and fuel efficiency difference: 95 octane outperforms 92 octane in terms of power and fuel efficiency due to its higher isooctane content.
