What grade of gasoline does the Teana use?
3 Answers
The Teana uses 92-octane gasoline. Main components of gasoline: The main components of gasoline are hydrocarbons such as C5-C12 alkanes, cycloalkanes, alkenes, and aromatic hydrocarbons. The difference between different grades of gasoline lies in subtle variations in the content of alkenes and aromatic hydrocarbons, as well as differences in the content of the gasoline additive MTBE. Higher-grade gasoline contains higher levels of alkenes, aromatic hydrocarbons, and MTBE. Octane rating: Different fuel grades have different octane ratings, and the fuel grade is determined by the octane value. Higher-grade fuels have higher octane ratings, which provide better anti-knock performance. This results in smoother engine operation, reduced vehicle wear, and better protection for the engine.
I've been driving a Nissan Teana for several years and always use 92-octane gasoline, which is perfectly sufficient and cost-effective. The 92-octane rating is just right for the Teana's standard engine—it won't cause any issues and saves money. Nissan's official manual also recommends 92-octane, as the engine's compression ratio isn't high enough to justify the more expensive 95-octane fuel. I usually refuel at major-brand stations to ensure fuel quality and avoid carbon buildup from low-grade gas at smaller stations. Regular maintenance is crucial, like changing the engine oil and air filters, to keep the engine running smoothly. If you drive a sportier version, you might need 95-octane, but for a regular Teana, 92-octane is all you need. Whether for long trips or city commutes, fuel consumption remains stable, so there's nothing to worry about. With simple maintenance and the right fuel grade, the car is reliable and durable.
From a technical perspective, I've studied the Altima's engine, and using 92-octane gasoline is just right. The 92 octane rating is more than sufficient for daily compression ratio engines, preventing knocking, while 95-octane only offers slight advantages in high-performance versions but costs more. Why? The standard Altima engine is well-optimized for 92-octane, making higher-octane fuel unnecessary. Always choose unleaded gasoline to protect the catalytic converter. Long-term use of lower-octane fuel might cause slight knocking, so sticking with 92-octane is hassle-free. For maintenance, occasionally check the spark plugs and fuel pump condition to ensure the injection system stays clean. This ensures smooth driving, with fuel consumption around 7-8 liters per 100 km being normal, without any complex equipment to fuss over.
