What type of gasoline should be used for Nissan Sylphy?
2 Answers
Nissan Sylphy uses 92 and 95 octane gasoline. The following is relevant knowledge about gasoline characteristics: Volatility: Gasoline must rapidly vaporize and form a uniform combustible mixture with air in the engine cylinder, which is mainly determined by the gasoline's own volatility. Stability: The ability of gasoline to resist oxidation under normal temperature and liquid phase conditions is called the oxidation stability of gasoline, referred to as stability. Anti-knock property: The property that measures whether a fuel is prone to knocking is called anti-knock property. The anti-knock property of gasoline is expressed by the octane number. The higher the octane number of gasoline, the better the anti-knock property. Cleanliness: Gasoline often contains mechanical impurities and water. Mechanical impurities can cause serious consequences such as clogged oil passages and increased wear. Water mixed into gasoline will accelerate the oxidation of gasoline and form acidic aqueous solutions with low molecular weight organic acids in gasoline, corroding metals.
I've been driving a Nissan Sylphy for many years, and the car usually runs on 92-octane gasoline. The Sylphy is an economical family car, and its engine is designed for 92-octane fuel, making it the most cost-effective choice. Daily driving is smooth with good acceleration, and the fuel consumption is relatively low, averaging around 6 liters per 100 kilometers. Both the fuel cap and the user manual clearly recommend using 92-octane, so I never switch to a higher grade. Although some people think 95-octane might feel more powerful, in reality, there's little noticeable difference—it just costs more. Remember not to use lower-octane fuel, as it can lead to engine carbon buildup or insufficient power. For maintenance, regular oil and filter changes can extend the engine's lifespan. Driving a Sylphy is all about hassle-free and cost-effective motoring—92-octane is perfectly sufficient, even for long trips. Each fill-up costs around 200 yuan, and with only three or four refuels a month, it's very suitable for commuters.
