I was surprised how much of a buffer modern Mazdas keep. The "range" is based on 2 gallons hidden. At 3 gallons remaining, it appears as if you have 1 gallon remaining (i.e. 25-35 miles depending on your average gas mileage since the last reset.) So "0 miles remaining" happens when you really could go another 50-70 miles. This is based on the total gas tank size compared to how much it takes to fill, but also because I'm stubborn and have pushed it several miles past "0" out of curiosity (but not regularly, as I have no wish to overheat my fuel pump or run out of gas!)
