Couple of strange things I noticed on my first long trip. First filling the gas tank with fuel on first cut off stops 3 to 3.5 gallons shy of total tank capacity. If the gas pump has a slow pump handle I can put an additional 3 to 3.5 gallons into the tank which get me an extra 75 to 80 miles on a tank. Second, I have never had a car that gets better gas mileage around town than on the highway. Around town I get 29 to 31 miles to the gallon driving very conservative. On the highway at 70 to 75 mile an hour I can barely get 27 to 30 miles to the gallon. Did they not gear this car correctly? Also the car really has high RPM's at freeway speeds. Don't get me wrong I love this car, over all good gas mileage and a pleasure to drive. Just a little quirky to top off the tank. Other wise very happy with my first Mazda. An additional note: I can boost my gas mileage 1 to 2 MPG by using middle grade gas, have not tried 93 octane yet.
