    Well, there are here some "no brand" gas stations that offer cheaper prices, but prices are not that good. Imagine that 2 months ago, gas prices were up to 1,850€/l.

    Ouch! I hope that prices will stabilize. Thanks for the response.
    I still can't imagine how you did 2.9 l/100km for the whole tank :)

    Who are you talking to?
    I see you hit 63 a couple times. My personal best is 54.4.
    Did you have a Prius before you got your 2012? If so, what was your mileage in the winter out there in Nebraska?

    Great tank! When you fill up, what does your cruising range say? So far my best is 605 miles.

    Nope...just got my first one in April. It will be interesting to see what winter will be like. I am looking forward to the traction control and anti lock brakes though. ;)

    Sorry, I've never looked at the predicted range. But here are the actual ranges for the last five tanks: 563, 569, 603, 623, and 621. The average range since I got the car is 544 miles/tank.

    You can figure it out after the fact if you track your tank. Just add the mileage you put on your tank to the existing cruising range.

    This last tank went pretty well despite a long trip which dropped me from 66.6mpg at around 300miles to 64mpg. I had claw my way back up. RE the short tank; I thought I was going on a long trip today and I'd be testing AC wattage use but the trip was terminated too. lol

    07/08/2012
    Miles: 463.8
    Gallons Pumped: 7.477
    MFD = 65.1mpg
    Calculated = 62.3mpg
    MFD vs. Calculated = -2.79
    % Error = 4.49%
    Avg Spd = 38mph

    Tires: Energy Saver A/S at 44/42 cold pressure
    Temps: mostly high 90s in the evening and 55-60F in the morning commute.

    Not bad for my third tank. It took 2 1/2 weeks to get through it. Zero highway, but i did have a 80 mile round trip through some 50 mph hills, with traffic lights halfway up some of the hills.

    653.3 miles
    9.57 gallons
    $3.499/gallon
    $33.50 total
    68.3 calculated mpg
    72.7 computer mpg on tank.
    $0.0513/mile
    25 mph avg. speed

    As Cypress Hill used to sing "Insane in the membrane!"

    Very nice numbers! I'm jealous of the avg speed. I can only dream of no highway driving.

    525.8 miles
    9.628 gallons (2nd click; 9.455 gallons 1st click)
    $3.149/gallon after $0.10 per gallon discount
    $30.32 total
    54.6 calculated mpg (using 9.628 gallons)
    57.5 computer mpg on tank.
    $0.0577/mile
    24 mph avg. speed

    Pretty happy with my 4th tank, running with 17" wheels. Tires at 46/44.

    The last pip started blinking at 513 miles which, based on the calculated economy, means I had about 120 miles remaining before empty. I will confirm this on a couple more tanks and then will feel better about ignoring the evangelicals preaching getting gas right after the pip starts to blink. I routinely went 100 miles past the last pip blinking on my 2004 and expect to be able to do the same in the 2012.

    ^ Thanks, F8L. I have a long ways to go to catch up to your numbers. 60 avg ain't shabby at all.
