Should the Buick Envision use 92 or 95 octane gasoline?
2 Answers
The Buick Envision with a 1.5L displacement model uses 92 octane gasoline; the 2.0L displacement model uses 95 octane gasoline. Owners should choose the appropriate fuel based on the engine displacement, following the manufacturer's recommended fuel type. The Buick Envision has dimensions of 4686mm in length, 1839mm in width, and 1660mm in height, with a wheelbase of 2750mm, making it a 5-door, 5-seat SUV. The Buick Envision offers seven color options: Agate Red, Topaz Brown, Snow White, Pearl Black, Glacier Silver, Starry Purple, and Khaki Gold. The 1.5L turbocharged engine of the Buick Envision has a maximum power of 124kW, reaching its peak power at 5600 rpm, with a maximum torque of 250Nm available from 1700 to 4400 rpm.
My Buick Envision has been running for almost two years now. The official manual recommends using 95-octane fuel for its higher octane rating, which reduces the risk of knocking and ensures a smoother driving experience. While 92-octane gasoline is cheaper and can be used in emergencies, prolonged use may lead to reduced power or increased carbon deposits. From an economic standpoint, using 95-octane fuel might actually save money in the long run due to higher fuel efficiency and slightly lower consumption. For daily city commuting, 95-octane is the steady choice, but if you have no option during a long trip, 92-octane will do—just remember to check the fuel system afterward. Before switching fuel grades, it’s best to consult the 4S dealership, as each car’s tuning varies. Develop good habits: the label inside the fuel cap clearly states the recommended fuel—using the right one is the real way to maintain your car.
