Should the Buick Envision use 92 or 95 octane gasoline?
4 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.
I personally prefer using 95-octane gasoline for my Envision, as its engine has a high compression ratio. Using lower-grade fuel can easily cause issues. When refueling, I pay attention to the fuel quality—95-octane has stable octane levels, ensuring smooth acceleration, unlike when using 92-octane, which sometimes makes the engine shake like it's having a fit. Occasionally, when traveling and unable to find 95-octane, using 92-octane for short distances isn’t a big deal, but don’t make it a habit. Saving money is minor; engine repairs are the real expense. My neighbor used 92-octane long-term and later found clogged fuel injectors during maintenance, costing hundreds to clean. Remember, the fuel cap has the recommended grade—95-octane is the way to go. Also, during hot summer days, using higher-quality fuel is even more crucial to avoid the embarrassment of stalling midway.
My experience is that the Buick Envision must use 95-octane fuel. The fuel grade is related to the engine compression ratio. Lower-grade fuel can cause pre-ignition and knocking, which may result in reduced power at best or damage to components at worst. Although the owner's manual states that 92-octane can be used in emergencies, the trade-off is increased fuel consumption. Long-term use of lower-grade fuel not only wastes money but may also trigger warning lights. The most practical approach is to stick with 95-octane—it saves both hassle and money.
