Should the Buick Regal 2.0 use 92 or 95 octane gasoline?
2 Answers
The Buick Regal 2.0 should use 95 octane gasoline for more complete combustion and reduced carbon buildup. Here are some details about the Regal: 1. Exterior: The upgraded new Regal features a waterfall-style front grille with a metallic tri-shield emblem at the center. The three-dimensional combination headlights on both sides complement the teardrop-shaped side mirrors. 2. Interior: It offers two color options - black interior and gray/beige dual-tone interior. A silver trim strip runs across the entire T-shaped dashboard. The vehicle adopts Buick's signature ice-blue instrument lighting, which appears stable and non-glaring in low-light conditions.
As a veteran owner of a Buick Regal 2.0 for nearly three years, I find this issue quite common. Generally speaking, this car comes standard with 92-octane gasoline, which is sufficient for daily commuting needs and won't cause major problems. However, if you're after engine performance, 95-octane fuel has a higher octane rating, better preventing knocking during high-speed driving and offering smoother operation. In my experience, long-term use of 92-octane doesn't pose significant issues, though occasional slight vibrations may occur when accelerating on steep slopes. Switching to 95-octane does provide a noticeable improvement in power response. Of course, fuel choice should align with the manual's recommendation—Buick officially states that 92-octane is generally adequate, helping save on fuel costs. Personally, I'd suggest trying 95-octane during summer or frequent highway driving to feel the difference before deciding.
