The 3800 engines with the superchargers require premium gas. Higher octane fuel prevents engine from self ignition of oxygen and gas causing engine misfire.
The 1996 Buick Riviera Supercharged is designed to run on premium gasoline with an octane rating of 91 or higher. Using premium fuel helps optimize the performance of the supercharged engine, providing better power and efficiency. While it may operate on regular fuel, doing so could lead to reduced performance and potential engine knocking. It's recommended to use premium fuel for the best driving experience.
