Should the Encore use 92 or 95 octane gasoline?

The Encore should use 92 octane gasoline. The Encore is equipped with a naturally aspirated engine with either a 1.5L or 2.0L displacement, and it is perfectly fine to use 92 octane fuel; there is no need to use 95 octane. The quality of 95 octane and 92 octane gasoline is the same; the difference lies in the amount of anti-knock additive added. The anti-knock additive is used to suppress engine knocking. The Encore is a compact SUV launched by Buick, with a length of 4295 mm, a width of 1798 mm, a height of 1607 mm, and a wheelbase of 2570 mm. The front suspension of the Encore uses a MacPherson independent suspension, while the rear suspension uses a multi-link independent suspension. The multi-link independent suspension can improve the tire's contact with the ground, thereby enhancing traction. With improved traction, the car's handling and comfort are also enhanced.

I've been driving my Buick Encore for over four years now. At first, I tried saving money by using 92-octane gasoline. But after a few months, I noticed something was off – the car felt sluggish during acceleration, especially when running the AC in summer. The engine occasionally made knocking sounds, like mild detonation. After switching back to 95-octane fuel, the difference was night and day – much peppier acceleration, quicker throttle response, and smoother overall performance with stable fuel consumption. I checked the owner's manual which recommends 95-octane fuel to prevent engine knocking. Now regardless of gas price fluctuations, I exclusively use 95-octane. Though it costs a few cents more per liter, it reduces maintenance headaches and proves more cost-effective in the long run.

As a seasoned car repair professional, I'd recommend using 95-octane gasoline for turbocharged engines like the Buick Encore's. While 92-octane fuel with lower anti-knock index might work temporarily, prolonged use could lead to knocking issues, reduced performance, and increased carbon deposits. 95-octane ensures optimal engine operation and lowers failure risks. From my experience driving the Encore, I've noticed smoother acceleration, better throttle response, and slightly improved fuel efficiency with 95-octane. Always prioritize fuel quality - choose reputable gas stations to avoid impurities. Don't try saving small money with 92-octane; engine overhauls from premature wear will cost you far more.

I usually drive my Encore to work, and I've tried both 92 and 95 octane gasoline. The 92 octane is indeed cheaper, but the car sometimes shakes, accelerates slower, and consumes more fuel. After switching to 95 octane, the driving experience has become much more comfortable—more power, quicker starts, and hardly any issues. Now I always stick to 95 octane; it's more expensive but worth it. When choosing gasoline, pay attention to the gas station brand—don't risk major losses for small savings.
