Driving Habits:
* Gentle Acceleration: This is the single biggest factor. Avoid jackrabbit starts. Accelerate smoothly and gradually. The supercharger is most effective at higher RPMs, so easing into acceleration minimizes its use at lower speeds where it's least efficient.
* Maintain Consistent Speed: Cruising at a steady speed uses less fuel than constantly accelerating and braking. Use cruise control on highways whenever safe and practical.
* Anticipate Traffic: Look ahead and adjust your speed proactively to avoid sudden stops and starts. This helps avoid unnecessary throttle inputs and braking.
* Coast When Possible: Lift off the accelerator and let the car coast to a stop when approaching a red light or slowing down for traffic. Don't ride the brakes unnecessarily.
* Avoid Excessive Idling: Turn off your engine if you're stopped for more than a minute or so.
* Minimize Air Conditioning Use: AC significantly impacts fuel economy. Use it sparingly, especially at lower speeds, or roll down the windows instead (though this is less efficient at highway speeds due to wind resistance).
* Proper Tire Inflation: Under-inflated tires increase rolling resistance, leading to poorer gas mileage. Check and inflate your tires to the pressure recommended in your owner's manual (usually found on a sticker inside the driver's side doorjamb).
Maintenance:
* Regular Tune-Up: A well-maintained engine runs more efficiently. Ensure your engine receives regular tune-ups, including spark plug replacement, air filter replacement, and fuel filter replacement. These are especially important for a supercharged engine.
* Check for Leaks: Leaks in the intake system or vacuum lines can reduce engine performance and fuel economy.
* Keep the Supercharger in Good Condition: The supercharger itself needs maintenance. Consult your owner's manual or a Buick specialist for specific recommendations. Issues with the supercharger will drastically impact fuel economy.
* Use High-Quality Fuel: Using higher-octane fuel (as recommended in your owner's manual) can sometimes improve performance and slightly improve fuel economy, but the difference might be marginal.
Things to Consider (that are less likely to help significantly):
* Weight Reduction: Removing unnecessary weight from the car will improve fuel economy very slightly.
Realistic Expectations: You won't magically double your gas mileage. A supercharged V6 is inherently less fuel-efficient. Focus on consistent, smooth driving habits for the biggest impact. Even small improvements will add up over time and reduce your overall fuel costs.
