BS.
The overall majority of all gas in a area comes from the same refineries. The quality of the tanks at the station are more important

Don't put higher octane gas in your car than it requires, look in your manual. If you put in higher, then you are a COMPLETE IDIOT, ok that is really harsh, if you continue to do it after you read this, then you are one. A higher octane does not mean your engine will run cleaner or more efficient or have more power. Octane keeps fuel from combusting under pressure, the higher the compression (a higher performance engine) needs this to keep the fuel from combusting before the spark plug sends it spark (called detonation) which can destroy an engine. Lower compression cars (most) using high octane gas helps NOTHING, except sending you to the poor house.
