Is it better to use 92 or 95 octane gasoline for the CR-V?
2 Answers
For CR-V models equipped with naturally aspirated engines, 92 octane gasoline can be used; for models with turbocharged engines, it is recommended to use 95 octane gasoline. Below are specific details about refueling the car: 1. Although 95 octane gasoline has higher anti-knock properties and better performance, vehicles designed for lower octane should not blindly opt for higher octane gasoline. Higher octane numbers are more suitable for engines with larger compression ratios, while engines designed for 92 octane often have smaller compression ratios. Using 95 octane gasoline may increase engine knocking. 2. Different octane grades of gasoline should not be mixed. For example, mixing 92 and 95 octane gasoline, even if done occasionally, could potentially affect the engine over time, leading to issues such as carbon buildup in the engine and increased fuel consumption.
I've been driving a Honda CR-V for over a decade, and using 95-octane fuel is more suitable. While 92-octane is slightly cheaper, the CR-V's engine has a high compression ratio, making it prone to knocking with lower-octane fuel, which can cause the car to shake during acceleration and affect driving smoothness. Long-term use of 92-octane fuel increases fuel consumption because the engine automatically adjusts ignition timing to prevent knocking, reducing efficiency. The manual recommends 95-octane or higher to protect engine components like spark plugs and minimize maintenance issues. Additionally, 95-octane fuel has better purity, reducing carbon buildup risks and enhancing the car's durability. Although it costs a few cents more per liter, it saves money and hassle overall. I recommend making a habit of using 95-octane, especially for long trips or heavy loads, as it provides better safety assurance.
