What grade of gasoline should the Nissan Teana use?
2 Answers
The Teana comes with two engine options: a 2.0L naturally aspirated engine and a 2.0T turbocharged engine. The 2.0L naturally aspirated engine requires 92-octane gasoline, while the 2.0T turbocharged engine requires 95-octane gasoline. It is recommended to follow the specifications in the owner's manual. 92-octane gasoline has an octane rating of 92 and contains 8% heptane, making it suitable for mid-range vehicles. 95-octane gasoline consists of 95% isooctane and 3% heptane. The Teana is a flagship mid-to-high-end luxury sedan under the NISSAN brand, with body dimensions of 4901mm in length, 1850mm in width, 1447mm in height, and a wheelbase of 2825mm.
I've been driving a Nissan Teana for almost five years now. At the beginning, I wasn't sure which type of gasoline to use, but later I checked the owner's manual and found that the manufacturer recommends 92-octane gasoline. This is mainly because the engine's compression ratio is designed to match best with 92-octane gasoline, ensuring smooth combustion and preventing knocking sounds that could harm the engine. I've always used 92-octane, and it performs well both in city commuting and on highways, with reasonable fuel consumption. Some people might think about using 95-octane gasoline, expecting better performance, but actual tests show no significant difference. It just costs more without any environmental benefits. Gasoline octane ratings may vary by region; for example, in Europe, 91-octane is common, while in China, 92-octane is the standard. It's a good habit to check the gasoline grade to avoid misfueling, which could cause emission issues or long-term engine damage. Checking the fuel cap label during regular maintenance is a convenient way to stay informed.
