Can the Buick Regal Use 92 Octane Gasoline?
2 Answers
The Buick Regal 1.5T model uses 92 octane gasoline, while the 2.0T model requires 95 octane gasoline. Only when the octane rating of the gasoline meets the engine's compression ratio requirements can the vehicle's performance and fuel efficiency be fully optimized. Regal owners can refer to the car's user manual, which specifies the recommended fuel grade. Introduction to gasoline grades: The gasoline grade represents the octane rating of the fuel. The higher the grade, the higher the octane rating, indicating better anti-knock performance. Better anti-knock performance ensures smoother engine operation, reduces wear, and provides better engine protection. However, a higher fuel grade is not always better. Introduction to compression ratio: Every car's manual includes a term called compression ratio. Generally, if a high-compression-ratio engine uses low-grade gasoline, it can lead to incomplete combustion, severe engine vibration, reduced power output, component damage, increased fuel consumption, and poor driving performance.
I've been using my Buick Regal for several years, always filling it with 92-octane gasoline, and never had any problems. The manual clearly states that 92-octane or higher can be used, with 92 being the minimum requirement. The engine is designed with an automatic adjustment function to adapt to lower octane ratings and prevent knocking. This way, refueling is both economical and convenient, saving me dozens of yuan each month. The key is to go to reputable gas stations to ensure the fuel is clean and free from impurities. Consistently following this practice protects the engine and extends its lifespan. Occasionally filling up with lower-octane fuel by mistake is nothing to panic about—the system will compensate. Remember, the manual is the best guide; don't blindly believe in premium fuel.
