    As of today, my tank is at 116.7 over 813.9 miles with 8 of 20 bars on the gauge. The tank average seems to go up a couple of tenths every day. I'm not sure there is enough fuel left for me to get to 120 mpg by the end of the tank but I'll do my best.

    Andrew, with a little help with the missing anti-evaporative system on most European Prius :D so I filled up 14+gallon today

    My best day up to now is 70.4. Hope I'll reach an average of 68.1 this tank so I can reach my 1st clean kilo-tank :cool:

    Air quality in Toulouse should be at near pollution alert level during next days :(
    I don't know if this is the reason, or he has same pollen allergy as his mother, but Ludo has an irritated and inflated eye since a couple day.

    Denis.

    It occurred to me that I last filled on 5/11/2012. Since then, I have been riding my Harley and only used the car a couple times to run the kids to baseball/softball practice, and one run for pizza.

    Unless something comes up I will not be filling again this challenge.

    Looks like I won't be doing marathon division for the next challenge. I am interning 4 miles from home three days a week.
     
  6. back above 35 for this fill up. 36.3 to be exact :)

    Up over 46 for this tank. Slowly improving...

    Filled up this afternoon. Was pleasantly surprised with the result as it was a record 52.8mpg :D :D :D (UG was showing 51.97) and a record distance tank of 733.0 :D and I still had 1 gallon left. A new double PR :woot:

    Excellent, Eric! I'll eventually get another tank posted! :p

    6/7/2012 marks one year of driving smarter!!!
    This is the third consecutive >400 mile tank.

    22 days on this tank, with an elapsed (engine on) time of 14 hours and 48 minutes (trip computer figure).
    95% city driving.
    Average speed of 29 MPH (trip computer figure).
    A computed 0.7564 gallons per hour average for the tank (spreadsheet figure) UG reported 0.79 gallons per hour.
    Cost per mile of $0.090 (spreadsheet figure), $3.379 per gallon.
    11.195 gallons consumed over 435.3 (adjusted) miles for a whopping 38.8853 MPG.

    No highway to speak of this time. Just my usual daily grind.

    Hi , Jon. Your average speed looks a lot like mine. But for some reason , I consider my commute to be 50/50 city/highway. I consider highway to be anytime I am in top gear,locked,for at least a mile before stopping. I'm not criticising you , just noting that we look at it differently.

    Also , for the tank that you calculated (38.88) what did the Elantra's Afcd show ?
    I'm assuming it does have one , but don't remember for sure.

    I'm such a dummy at times. Late last month I was thinking it was the end of the challenge, but now realize that it ends at the end of June. Anyway, Monday I will have gone an entire month on my current tank. Unfortunately, all my driving on this tank has been done under time constraints, very short trips and mainly with kids in the car.

    I think this will be my worst tank of the year. Currently I'm showing 42.7 mpg with just over an eighth of a tank left.

    Kirk, for you that's horrible ! But I do understand that not all tanks will have ideal driving conditions.

    Edwin,

    Just what are you trying to say :p:D.
    I guess we do look at "highway" differently.
    Just today, I was in Winston-Salem and there were plenty of times where I was in top gear/locked for at least a mile before a stop light, but it was over and over and over and over, which I would consider "city".
    My higher-than-it-should-be average is probably caused by a 6 (or so) mile stretch leaving from home.
    The short version:
    Leave my (uphill) driveway
    Stop
    Turn, accelerate to ~40-45 then N coast to the stop sign (I usually roll right up to it), <1 mile
    Turn and accelerate on a hilly section until speed reaches ~60 (more throttle on downhill, less throttle on the uphills)
    N coast for a while through a hilly section (just about a mile) until I reach a particular hill
    DWL up that hill (not too steep)
    N coast for a little while after cresting that hill, keeping my speed above 35
    DFCO down a steep-ish curvy hill
    DWL up another hill
    Maintain ~35-45 on a straight section
    N coast up a smaller hill, then down hill again
    DWL up a long curvy hill (I like to keep the aMPG from dropping below 40 at this point, but that doesn't always happen)
    DFCO down another steep-ish curvy hill
    N coast up the next hill to the stop sign.

    That takes me to the half way point, and I can't remember the last time I went straight to work, as I usually make a stop or two on the way.

    I lose lock-up frequently (it's either that, or go backwards on some hills :D) and my speed changes so much that I could never consider that to be "highway".

    I normally end up with ~40+ MPG on my first stop, depending on where I'm going.
    Then from there it's stop/go-ish (some times I can time/smart brake everything, sometimes I can't) until I get to work (which is up another hill, noticing a trend?).

    My definition of highway is pretty similar to yours, just for longer distances between stops.

    The Elantra's in-car aMPG registered 39.7 on this tank, so it's not too far off, once you account for the odometer's under-report (3.5%).

    I didn't intend for this post to be this long...
    Wups...

    Now, I'm using the term "DWL" in these instances as locking the throttle to keep the engine load gauge ~80% going up those hills.
    My speed will drop down to ~30-35 most of the time on the longer hills and then stay there, until I reach the top.
    I may be wrong and please correct me if that is the case.

    Jon

    P.S. They don't call this area the "Foothills" for nothin'...

    Thanks, Jon. It sounds like you are getting pretty good results on that hilly commute.

    I do the best I can, well... most of the time :eek:.
    Over the past year, I've slowly changed my methods on most hills.
    I've went from locking the throttle/load, to gaining speed before the hill and letting off the throttle bit by bit as I go up the hill and now I'm doing it the second way, but instead of just letting off the throttle on the way up, I'll N coast up to the crest and gain my speed while still in "N".

    IMO, the only thing better (for me, in an auto trans) than locking in an efficient load while crawling up a hill, is to crawl up the hill in "N" :D.
