* Engine variations: Even within the same model year and engine size, there can be different engine variations. The spark plug gap can vary depending on the specific engine code, the type of spark plug recommended, and other factors.
* Safety and accuracy: Providing incorrect information about spark plug gaps could lead to engine damage or safety hazards.
How to find the correct spark plug gap:
1. Consult your owner's manual: This is the most reliable source for information specific to your vehicle.
2. Look at the spark plug packaging: The packaging of new spark plugs often includes the recommended gap.
3. Refer to a reputable repair manual: Haynes, Chilton, and other repair manual publishers provide detailed information on specific vehicles.
4. Contact a qualified mechanic: Your local mechanic can access the correct specifications and provide guidance on the proper spark plug gap for your 1995 Buick Regal 3.1 liter engine.
Remember: Always use the correct spark plug gap recommended by the manufacturer. A too-wide gap can cause misfiring, while a too-narrow gap can lead to fouling or damage to the spark plug.
