    Do you coast while driving?

    That's Awesome! I checked mine today and it was 40.6 but I'm betting it will go up a lot more this summer. Car has 670mi now.

    I coast up to traffic lights quite a bit if I can do it without ticking people off behind me. Sometimes I coast in neutral and other times with the car still in gear. I never do engine-off coasting, which I think some people on here might do.

    Today I had both my gauges reading 50 and 51mpg on my work commute. I realized just how awesome this car coasts in neutral and even in gear. Seems to go a long while even on flat ground. I will use the technique more. I always did a lil before lights but not on flat ground coasting.

    I found the factory gauge quite accurate. It was almost always right on. I coast a fair amount. How we're you guys measuring your "actual usage"? Were you filling up at the same pump every time @ just let it click off?
    I always go after the click. I have gotten almost 9 liters after the click once. I don't like filling up that much if I can avoid it.

    Side note wtf happened to gas prices this week? Haven't had to fill and looked at prices yesterday. sheesh

    If you get a Scangauage (which will display your instant mpg), you will observe a big difference in coasting techniques. Sometimes when the car is coasting under the right conditions, the instant mpg reading will jump from 100-200mpg to 9999mpg. I think under the right conditions, the computer can almost shut off the injectors completely when the car is coasting.

    I have a Scan gauge E. And I get it to 9999 all the time. That's what I shoot for. I hit 55 the other night on the SG and cars computer.

    Sounds like you've got it figured out. Unless you are driving under perfect conditions all the time, that's the only way to get one of these cars knocking on 50 mpg consistently.

    Yeah I used to have a autometer ecometer in my last car, 08 elantra for the last 6+ years so I figured out long ago how to manipulate the gas pedal to work in my favor haha

    The injectors are shut off. It is called "Deceleration Fuel Cut-Off" (DCFO). On my Mirage the injectors kick back on at about 1200 rpm when I am engine-braking to a stop. Not sure if this is what you are talking about.
