Can the Buick GL8 use 92-octane gasoline?
2 Answers
Whether the Buick GL8 can use 92-octane gasoline depends on its configuration: 1. The Buick GL8 2.5L can use 92-octane gasoline; 2. The Buick GL8 2.0L requires 95-octane or higher gasoline. Taking the 2021 Buick GL8 as an example, its body dimensions are: length 5238mm, width 1878mm, height 1776mm, with a wheelbase of 3088mm and a fuel tank capacity of 66 liters. The 2021 Buick GL8 is equipped with a 2.0T turbocharged engine, with a maximum power of 174kW and a maximum torque of 350Nm, paired with a 9-speed automatic transmission.
I've been driving a GL8 for three years, and the salesperson specifically told me to use 95-octane gasoline when I bought the car. Once on a long trip, I had to use 92-octane because 95 wasn't available at the gas station, and I immediately noticed the engine noise increased and acceleration felt sluggish. After checking the manual at home, I found that the new 2.0T engine has a compression ratio of 9.5:1, and turbocharged models are prone to knocking with lower-octane fuel. Now I strictly stick to 95-octane, even though it costs a few cents more per liter—adding up to about 30+ RMB more per tank. My friend with an older 2.4L model has been using 92-octane without issues, so it really depends on the model year and engine. Nowadays, 95-octane often has promotions, making the price difference even smaller—definitely not worth risking engine health to save a few bucks.
