Well, there are a lot factors involved. Was he doing the same type of driving (same ratio of highway vs. city) when he measured fuel consuption with both set-ups? Was one possibly during a time that he may have been using the A/C more? Did he merely measure one tank of gas with each set-up? Did he fill up at the exact same pump that he first filled up at in order to measure the consumption.
That last point may sound crazy, but I found that there is big difference in when pumps shut off when the tank is full. I filled up one morning in Anniston and drove 50 miles to work. During lunch, I filled up and it took over 3 gallons to fill it back up. When I got back to Anniston, I filled back up at the same pump and it took just over 1 gallon.
My conclusion is that my coupe must get better gas milage when traveling east-bound for some reason.
