Premium gasoline costs more for two reasons. It costs more to make. And, there's more profit added to premium by refiners and retailers. But, premium gasoline doesn't cost more because it is better.

Premium gasoline has a higher octane rating. Higher octane is only one thing: an index which indicates the gasoline's ability to overcome knocking or pinging in engines. That's all. If your car doesn't knock or ping on lower octane gasoline, paying for higher octane is a waste of your money. And, rest assured that the octane level posted at the pump is a minimum level for each grade. QuikTrip ensures the octane never falls below this level.

Higher octane does not mean better quality and it will not result in more power, better performance, greater gas mileage or anything else.

Some high performance cars were designed to run on premium gasoline. In that case, the owner's manual will clearly state you should use only premium gasoline in that vehicle. That's what premium was made for.

Why does QuikTrip expose the premium myth? After all, we stand to make more money as long as some people continue to believe the myth.

The economics of doing the right thing are pretty simple. QuikTrip gives you the facts rather than trying to sell you myths. You test the facts and find they are true. You save money. You buy more gasoline from QuikTrip. We overcome any short-term loss by selling more gasoline.

You win. We win. It's that simple.
