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

If you cherish your vehicle and can afford the cost, it is best to use 95 octane gasoline. Here are the detailed explanations: 1. The manufacturer of the Honda Avancier requires the use of 92 octane or higher gasoline that meets national standards, and a fuel additive should be added every 5,000 kilometers. In fact, the Avancier can use either 92 or 95 octane gasoline, but there is not much difference in terms of fuel economy. 2. The Earth Dreams engine of the Avancier is designed with a minimum applicable gasoline octane rating of 92, which means using gasoline below 92 octane will cause engine knocking. 3. Using 92 octane may occasionally cause knocking, while using 95 octane will definitely prevent knocking. Of course, the chance of occasional knocking is very low, with 0 to 2 occurrences in 500 ignition cycles at 1,000 RPM, so the damage to the engine is minimal. 4. Although higher octane gasoline has better anti-knock performance, it does not necessarily mean that the highest 98 octane gasoline is suitable for all engines. If the engine is designed for a minimum of 95 octane, then using 98 octane is acceptable. However, for the Avancier, which is designed for a minimum of 92 octane, using 98 octane may result in incomplete combustion of the gasoline, not only wasting energy in the fuel but also increasing carbon deposits.
I've been driving the Avancier for several years and always use 92-octane fuel, which feels quite cost-effective. Saving a few cents per liter adds up to significant fuel cost savings each month, and the car's performance hasn't been affected—it runs smoothly for daily commutes. The Avancier's engine is designed to perform well with 92-octane, so using higher-grade fuel might not be worth the extra cost. I've also noticed that with 92-octane, fuel consumption stays stable at around 10 liters per 100 km in the city, and it's even more economical on highways. If the gas station offers discounts, filling up with 92-octane is a great deal. Of course, the manual says 92-octane or higher is fine, but I prefer 92—it's practical and saves money without the hassle of switching to 95-octane.
I enjoy driving the Avancier on long trips and am quite particular about fuel quality. After trying 95-octane gasoline a few times, I noticed quicker throttle response and smoother engine sound during acceleration, likely due to its higher octane rating reducing knock risk. But this comes down to personal preference—the Avancier runs fine on 92-octane, with 95 being more of a bonus. For daily driving, I opt for 95-octane to chase that extra performance edge, especially when climbing mountain slopes where power matters most. Price comparisons at the pump show 95-octane costs about ¥1 more per liter—not a huge long-term expense, but 92 is the economical choice. The manual recommends 92 as the baseline, so I strike a balance by using 95 occasionally for fun.
