Should the Teana 2.0L use 92 or 95 octane fuel?
2 Answers
All models of the Teana 2.0L require a minimum of 92 octane fuel. The octane rating of gasoline determines the timing of detonation, which essentially influences the engine's power output. The anti-knock performance of fuel varies depending on its composition. The higher the fuel's anti-knock performance, the higher the engine's compression ratio can be, improving both fuel economy and power output. Below is relevant information about engine oil: 1. Function of engine oil: Engine oil lubricates and reduces friction, aids in cooling, seals against leaks, prevents rust and corrosion, and provides shock absorption. It is often referred to as the 'blood' of a car. Choosing the right engine oil and changing it regularly helps maintain the engine in good condition and extends its lifespan. 2. Choosing engine oil: The best engine oil isn't necessarily the most expensive; it should be selected based on the characteristics of the car's engine and the driver's habits. Engine oil can be categorized by its suitability for winter or summer use. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, there's no need to select an oil with an excellent low-temperature viscosity grade.
I've been driving a Teana 2.0L for three years and have always used 92-octane gasoline without any issues. The Nissan manual clearly states 'recommended to use 91-octane or higher unleaded gasoline,' and in China, 92-octane meets this standard. The other day when I went to the 4S shop for maintenance, the technician specifically reminded me not to be fooled by gas stations into using higher-octane fuel. The compression ratio of this generation's MR20 engine is only 9.5:1, so it doesn't need 95-octane at all. Doing the math makes it even clearer: currently, 92-octane is more than 0.7 yuan cheaper per liter than 95-octane. Based on my monthly mileage of 1,000 kilometers, I can save 600 yuan a year on fuel costs. Of course, if you're particularly concerned about your car's well-being, using 95-octane isn't harmful, but there's really no need to spend the extra money.
