    After you have driven 180 miles see what the gauge reads. It is based on driving habits and avg mpg, no way it knows exactly how many miles you can go on any given tank of fuel. It's an estimate in other words. Anyone else use the car? M.T.E. numbers should increase with good driving skills!

    No I'm the only 1 to drive it to me its just odd because when I would fill up when I first got the car my distance to empty was 200 mile higher. Say I'm at a quarter tank my car will let me know that I have 25 miles left if I keep driving the float will let me know how many gallons and the distance until empty will let me know how many miles I have left just not understanding why it used to read 370 on every full tank and know its in the 100's
