Should the Teana use 92 or 95 octane gasoline?
2 Answers
The Teana with a 2.0L naturally aspirated engine should use 92 octane gasoline, while the model with a 2.0L turbocharged engine requires 95 octane gasoline. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, making it suitable for mid-range vehicles with lower compression ratios. On the other hand, 95 octane gasoline contains 95% isooctane and 3% n-heptane, and is recommended for engines with higher compression ratios. The Teana measures 4901mm in length, 1850mm in width, and 1450mm in height, with a wheelbase of 2825mm. It is a 4-door, 5-seater sedan featuring a CVT transmission and a top speed of 197 km/h. The vehicle is equipped with a body stability control system, traction control system, brake assist system, electronic brake-force distribution system, and ABS anti-lock braking system.
I have some thoughts on whether the Teana should use 92 or 95 octane gasoline. I usually pay attention to saving money when driving, especially now that fuel prices fluctuate a lot. For family cars like the Teana, the engine design itself is compatible with 92 octane gasoline, and the compression ratio is not particularly high, so using 92 is perfectly fine. From an economic perspective, 95 octane is significantly more expensive than 92—filling up a tank might cost dozens of yuan more, but the actual performance improvement is minimal—at best, it might reduce knocking sounds during aggressive driving, but for daily commuting, the money saved can be used to fuel the car for longer. The vehicle manual also clearly recommends 92 octane, and I’ve followed it for years without any issues. I suggest everyone avoid unnecessary upgrades; the extra cost is better saved for maintenance. Remember, higher octane doesn’t necessarily mean better—making a reasonable choice is what really matters.
