What octane gasoline should be used for PCX160?
2 Answers
PCX160 uses 95 octane gasoline. Composition of 95 octane gasoline: 95 octane gasoline is composed of 95% isooctane and 3% n-heptane. High octane gasoline should be used when the engine compression ratio is high. If low octane gasoline is used with a high compression ratio, it may cause abnormal combustion, resulting in knocking, increased fuel consumption, and reduced driving power. High compression ratio engines can also use lower octane gasoline, but the selection of gasoline octane should not be blindly based on the compression ratio. Instead, follow the manufacturer's requirements for refueling. Significance of 95 octane gasoline: The implementation of the standard will help improve the overall quality of China's automotive gasoline, reduce vehicle emissions, and decrease nitrogen oxide and particulate emissions by 25% to 80% for new vehicles. For in-use vehicles, emissions can be reduced by 10% to 15% overall. This standard is of great significance for protecting the environment and improving air quality.
I checked the Honda owner's manual, which clearly recommends using unleaded gasoline with an octane rating of 91 or higher for the PCX 160, typically labeled as 92, 95, or 98. This recommendation stems from the engine's design compression ratio requirements. Higher-octane gasoline prevents knocking, ensures smooth power delivery, and extends engine life. During maintenance, I always prioritize 95-octane fuel due to its high compatibility and widespread availability. In daily riding, I've found that following the manual's instructions helps avoid maintenance issues like carbon buildup or performance degradation. Regularly replacing the air filter and inspecting the fuel system are equally important, collectively ensuring optimal vehicle condition. If you're new to riding, simply filling up with 92 or 95 at the gas station is straightforward and safe.
