Not sure what they use in premium gasoline to make it a premium, but the higher the octane the less BTU gasoline has. Hence you should get lower gas mileage. That is why you get lower gas mileage with ethanol. It has higher octane and less BTU's. You can get more power from it but takes more of it.
