According to the official vehicle manual recommendation, the Haoying should use 92-octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find this information on the fuel tank cap, which will also indicate the recommended grade. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. However, with the use of some new technologies, the compression ratio alone cannot determine the appropriate gasoline grade, as high-compression engines can also be tuned to use lower-octane gasoline. This is because, in addition to the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane rating, the higher the octane value and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the Honda Haoying occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, using higher-octane gasoline will not cause damage, but the increase in octane value will alter the fuel's ignition point, leading to delayed combustion in the engine. This means the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher-octane gasoline, using lower-octane gasoline can cause engine knocking. Because the octane value is too low, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance can make the engine run very unstably. If the knocking is imperceptible, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

















I've been driving a Breeze for several years, always using 92-octane gasoline, and the engine feels quite powerful with no issues in both city and highway driving. The manual clearly states that 92-octane is recommended and fully compatible with the engine design. Occasionally trying 95-octane might make the engine sound slightly quieter, but the higher cost isn't worth it in the long run—saving on fuel expenses is more economical. During long road trips, the average fuel consumption with 92-octane is around 8 liters per 100 km, with no loss in power, and it handles uphill climbs or sudden acceleration smoothly. My advice is not to be swayed by others into using higher-octane fuel—stick with 92-octane for peace of mind, cost savings, and to avoid unnecessary fuel waste. Just remember to choose reputable gas stations, as cleaner fuel is better for your car.

From an engine technology perspective, the Breeze's compression ratio is perfectly matched with 92-octane gasoline, as the octane rating fully meets anti-knock requirements. While using 95-octane is possible, the engine ECU will adjust ignition timing without delivering substantial performance improvements, just extra cost. 92-octane offers higher combustion efficiency, maximizing the Honda i-VTEC system's effectiveness. For daily driving, 92-octane suffices with stable fuel consumption even at highway speeds—no need to pursue higher grades wastefully. Saving money and resources is more practical; just ensure reliable fuel quality from standard gas stations.

I stick with 92-octane fuel purely to save money—it cuts my monthly fuel costs by tens of dollars compared to 95-octane, with no performance compromise in the CR-V. The power is ample for city commutes and short trips; 95-octane might offer slightly smoother starts, but the difference is negligible and hardly justifies the lower cost-efficiency. Saving hundreds yearly means more budget for maintenance or car accessories—practical and worry-free.

For car , I trust the manual's recommendation to use 92-octane fuel. Honda engines are well-matched, ensuring clean combustion and reducing carbon deposit risks. While using 95-octane is harmless, it might be overprotective and a waste of money. My Honda Haoying has been running on 92-octane for three years, maintaining a fuel consumption of around 8L with no engine issues. Regular checks and genuine oil products are the most crucial factors.

As a new owner, I checked the Haoying manual which recommends using 92-octane gasoline, and the salesperson also confirmed that upgrading to 95-octane is unnecessary. I tried 95-octane and felt a slight improvement in initial acceleration, but it's more expensive and not worth it. Sticking with 92-octane keeps the engine running smoothly with well-controlled fuel consumption. Simply following the manufacturer's guidance saves both hassle and money.
