it will show you instant mpg
the mpg you get everysecond
drive like a racecar driver it will show low mpg
drive like a champion trying to save fuel you will get high mpg
I can move my foot up or down on the gas to hold 55 but I can see the least amount of gas I need. I can tell in my car anything over 64mph is low mpg or under 32mph I now know I need to drive with a light foot between 32mph-64mph
I would have never known this without a mpg gauge
