What kind of fuel does the Buick GL8 use?
3 Answers
Buick GL8 uses 97-octane gasoline. Additional content about the Buick GL8's drawbacks: 1. The single sliding door is not powerful enough: As a business MPV, this aspect is not well-developed. Even the top model does not come with dual sliding doors. 2. Fuel economy is slightly inferior: With a 2.0T engine, 12 liters per 100 km in the city is normal, but given the car's large size and weight, it's unlikely to have very low fuel consumption. Compared to the Honda Elysion and Odyssey, the fuel consumption is indeed higher. 3. The transmission logic is not very reasonable: GM's transmissions have always been mediocre, without a truly outstanding one. The car's transmission is not very proactive in shifting up or down, and the logic is not very clear.
I drive a Buick GL8 as the family's main vehicle, using it for daily school runs or trips. Filling up with 95-octane unleaded gasoline is the safest choice. The manual recommends either 92 or 95 octane, but 95's higher octane rating helps reduce engine knocking issues, protects engine longevity, and enhances performance. While 92 octane saves some money, long-term use may lead to decreased fuel efficiency and increased carbon deposits—more harm than good. I prefer refueling at major stations like Sinopec to avoid substandard fuel. Never mix different octane grades to prevent sensor errors or system damage. Get spark plugs and fuel lines checked every 20,000 km—it saves money and ensures peace of mind.
Our family of four relies entirely on the GL8 for transportation, and using 95-octane gasoline gives us peace of mind. The manual specifies 92 or 95 unleaded gasoline, and I find that 95-octane provides smoother acceleration and slightly lower fuel consumption. While 92-octane is cheaper, I've tried it a few times and noticed idle vibration, which affects the driving experience. Regularly adding fuel additives to prevent carbon buildup is very effective. Poor fuel quality may clog the fuel pump, leading to unnecessary repair costs. Take advantage of gas station promotions or membership cards to save money, and don't delay maintenance cycles—keep them in sync with regular servicing.
