2 Answers
The Buick Regal GS has a fuel tank capacity of 60 liters, and it is recommended to fill it up to 80%. The manufacturer suggests using 95-octane gasoline. Below is relevant information: Exterior Design: Under the influence of sculptural aesthetics, the all-new Buick Regal GS boasts an increasingly striking and eye-catching style. Equipped with new aerodynamic body kits and with expert attention to styling details, the all-new Regal GS appears lower, wider, and more dynamic. Powertrain: The Regal GS comes standard with General Motors' flagship powertrain combination, consisting of the eighth-generation Ecotec 2.0T variable-cylinder turbocharged engine and a 9-speed HYDRA-MATIC intelligent transmission. It delivers a maximum power output of 174 kW and achieves a peak torque of 350 N·m across a broad rpm range of 1500-4000 rpm.
Regarding what type of gasoline to use for the Regal GS, I've driven it for several years and believe it's best to choose 95-octane gasoline. The car's engine is designed for high performance with a high compression ratio. Using lower-octane fuel like 92 can easily cause knocking issues, resulting in engine vibration and reduced power. I've personally tried 92-octane and clearly felt the acceleration was less smooth. After switching to 95, the engine noise became quieter, and power delivery was more stable at high speeds. From a long-term maintenance perspective, although 95-octane is slightly more expensive, it prevents engine damage and saves on repair costs. The manual also explicitly recommends high-octane 95 fuel. Remember to choose reputable gas stations and avoid small roadside ones, as fuel quality varies greatly. Additionally, the GS is a sports model—using the right fuel ensures optimal performance. Don't compromise the experience to save a little money.
