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