What Grade of Gasoline is Suitable for the Avalon?
2 Answers
Avalon is suitable for 92-octane gasoline. Different grades of gasoline have different octane ratings. The higher the grade, the higher the octane rating, and the better the anti-knock performance of the gasoline. Typically, high-performance naturally aspirated engines or turbocharged engines require 95-octane or even higher-grade gasoline. The Avalon is a luxury sedan produced by Toyota, with body dimensions of 4975mm in length, 1850mm in width, and 1450mm in height, and a wheelbase of 2870mm. The Avalon is equipped with two engines: a 2.0-liter naturally aspirated engine and a 2.5-liter naturally aspirated engine. The front suspension uses a MacPherson independent suspension, while the rear suspension employs an E-type multi-link independent suspension.
I've been driving the Asian Dragon hybrid version for two years, always using 92-octane gasoline, and the car's condition has been excellent. The engine was originally tuned to the 92-octane standard during design, so using higher octane is purely a waste of money. You see, 92-octane is several cents cheaper per liter than 95-octane at the gas station, saving hundreds of dollars a year—enough for two maintenance services. Moreover, Toyota engines have strong anti-knock capabilities; I've pushed it to 140 km/h on the highway without ever hearing any knocking sounds. Inside the fuel cap, there's a label that says 'Recommended 92-octane or higher unleaded gasoline,' and page 152 of the manual clearly states that 92-octane is sufficient. There's really no need to迷信 high-octane gasoline. My neighbor insists on using 98-octane, but there's no difference in performance, just extra money spent.
