Using regular gas will likely lead to the following problems:
* Detonation (Knocking): The higher compression ratio and forced induction (supercharger) of the engine make it much more susceptible to detonation. Regular gas has a lower octane rating, meaning it's more prone to ignite prematurely, leading to knocking. This knocking can damage engine components over time, including pistons, connecting rods, and the engine block itself.
* Reduced Power and Performance: The engine's computer may retard timing to prevent detonation, resulting in a noticeable loss of power and performance. The car will feel sluggish and less responsive.
* Increased Emissions: Detonation can increase emissions of harmful pollutants.
* Premature Wear: The constant stress of detonation accelerates wear and tear on the engine, leading to a shorter lifespan.
In short, while you might save a little money on fuel initially, using regular gas in a Buick 3800 Supercharged engine will almost certainly cost you more in the long run through repairs or even engine failure. Always use the recommended premium fuel.
