A few years ago I was commuting 180 miles a day in a Silverado that got 18MPG so I was burning 10 gallons of gas per day. That can lead to desperation at the pump. At that time Speedway was usually 5 cents per gallon less than BP so I was buying it regularly. I decided to see if the BP was worth the extra money or not. I logged each tank and only compared tanks used only for commuting, no weekend in-town driving. After I had 10 tanks of each I found that the cost of the BP was 1.6% more but the mileage was 8.3% better.

Not all engines respond the same, my Impala doesn't seem to have a preference, at least not that I have found yet.
