What type of gasoline does the Buick Excelle use?
2 Answers
The Buick Excelle can use 92-octane gasoline, but if you have higher requirements, you can also choose 95-octane gasoline. Additional information: The differences between 95-octane and 92-octane gasoline are as follows: 1. Different ratios of n-heptane and isooctane: 95-octane gasoline contains 95% isooctane and 5% n-heptane; 92-octane gasoline contains 92% isooctane and 8% n-heptane. 2. Different anti-knock properties: The anti-knock index of 95-octane gasoline is 90; The anti-knock index of 92-octane gasoline must not be less than 87.
I've been driving a Buick Excelle for years and found that this car runs best on 92-octane gasoline. Veteran driver experience tells us that the Excelle's engine has a relatively low compression ratio, so 92-octane fuel perfectly matches its anti-knock requirements—no need to waste money on 95-octane. I remember back in 2003 when the first-generation Excelle was launched, the standard was 93-octane. Now that 93 isn't available, 92-octane works just fine. I've driven both the 2010 and 2017 models, always filling up with Sinopec's 92-octane fuel—it delivers stable power on highways and good fuel economy for city commutes. Using 95-octane by mistake might not cause immediate issues, but it’s a waste of money in the long run. On the other hand, using lower-grade 90-octane fuel could trigger engine knocking and shorten engine life. During maintenance, remember to check the fuel lines and filters—it keeps the car running smoother. The key is to avoid mixing fuel types; stick to one consistently for both cost savings and peace of mind.
