Should the Buick Excelle use 92 or 95 octane gasoline?
2 Answers
The Buick Excelle uses 92 octane or higher gasoline, with the following details: 1. Using 95 octane gasoline in the Buick Excelle will not have a significant effect on improving power or reducing fuel economy. 2. Gasoline below 92 octane or that does not meet standards must not be used, otherwise the engine and emission system will be damaged. 3. The octane rating of gasoline represents its anti-knock performance; the higher the octane value, the better the anti-knock performance of the gasoline. Here is some knowledge about the car combustion process: 1. When gasoline burns in the cylinder, knocking may occur due to carbon deposits inside the cylinder. 2. Knocking in modern cars like the Buick Excelle is mainly related to carbon deposits in the cylinder or fuel quality. Knocking can have a significant impact on the piston and connecting rod components, and prolonged knocking can damage these components, with severe cases leading to engine failure.
As a veteran driver who has been driving a Buick Excelle for over a decade, I've always used 92-octane gasoline without any issues. The Excelle's engine is designed and optimized for 92-octane fuel with its moderate compression ratio. After years of use, both power output and fuel consumption remain consistently stable. While 95-octane gasoline does have a higher rating and better anti-knock properties, it's unnecessary for the Excelle—just more expensive and wasteful. I know many fellow Excelle owners, most of whom use 92-octane with uniformly positive feedback. The key is to develop good refueling habits: choose reputable gas stations to avoid low-quality fuel that could harm the engine, and always check the recommended fuel label near the door or the owner's manual before filling up—both clearly state that 92-octane is perfectly safe. The money saved long-term can be used for regular maintenance, which is more practical than chasing higher octane ratings. Don't fall for myths; the Excelle isn't a sports car, and 92-octane fully meets its daily driving needs.
