    I found out a couple of things this morning.

    1- Covering the windshield overnight does indeed prevent frost from forming on it!
    2- The windshield is still cold enough that any water which hits it will freeze, greatly reducing the effectiveness of point #1.

    The windshield started to haze a bit when I started driving, so I turned on the wipers. Big mistake; the ice on the wiper blades smeared onto the windshield and froze again. So I tried the washer fluid. Bigger mistake; the fluid was spread into a layer by the wipers and froze. So I had a nice frost layer on my windshield, and I was still driving! I had to pull over, put the defroster on SUPER HIGH, and wait for it to melt off while the engine did its high-high cold idle (2250 RPM, yikes!) getting 0 MPG the whole time.

    ....This tank is gonna suck.... I'll probably be filling in the next day or two, and we'll see how badly it sucks.

    Horrible, horrible tank from me! It has dropped my average down enough to dump me into 2nd place. I do have lots of excuses, though... ;)

    They range from the very cold weather we have been having, to needing to warm up the car enough to melt the frost off of my windshield, to low battery voltage forcing me to give up FAS (for the most part), to a good bit of rain... And probably sun-spots and El Nino for that matter. ;)

    It just means I'll have to work even harder on the current tank, which is probably my final one for the Challenge!

    I finally put the radiator block back in, and I am thinking/hoping my battery has recovered enough for me to start FAS'ing again. We'll have to see....

    Wow i haven't even put in another tank and im in first! xD Wow from 170%+ down to low 160% goddamn your winters suck.

    That cold weather must hurt like hell, too bad i don't drive more often since i work where my Dad does so i just take a lift with him x) actually i think its been nearly 2 months since the last fillup though i need to do it soon as my brother is coming back from brisbane and he's gonna be using my car EEEEP!

    Sounds like a good time for a clinic to school him on hypermiling. :D

    I am filling up tonight and it will hurt :mad: But it should be the last fill up of the comp.

    Actually, we generally have very mild winters. The downside is that we aren't prepared for anything worse than "very mild". So I am trying to re-invent strategies for dealing with windshield frost, etc. Plus my battery is not real happy with me, and I'm trying to stretch its lifespan as much as I can.

    And, of course, the wind and the rain aren't good for FE either.

    If we had real winter around here, we (I) would have better coping mechanisms in place...

    BTW, I may not need another fill up by the time I put the car away--but I'll fill it just the same, 'cause I really am not happy with that last tank and I want to try to drag the average back up!! ;)

    Will no way I could bring mine back up :(

    404.0 / 19.352 = 20.8 (Avg down for the comp 0.6 MPG and 5% EPA)

    I guess that the temp was about 20 degrees cooler than the previous tanks and so it look like it took 2 MPG off for that temp. So, I am getting a feeling that my vechile has a sliding scale of 1 MPG for every 10 degrees up or down.

    This is the last tank as that one started on 11/19.

    Oh yeah, I really like the new look of the site. Kudos guys.:thumbs_up:

    Jason, my stats show a 3 mpg drop per 10 degrees, which works out to the same 5% / 10 degrees drop you're seeing.

    Am I sensing a winter handicap? :D

    I'll be participating in the next run :).

    Ricardo, you don't want me competing with a winter handicap. ;)

    Hey didn't you dropout!? :p

    I did, but you don't want me coming back with that kind of incentive!! It took a month of -20F temps last year to get my tank average down to just above highway rating. ;)

    Well, hypermiling just hit me with my second bill. The savings will more than pay for the cost of the new starter, but the OEM starter is not behaving well. It was a bit marginal before I started hypermiling, as of yesterday, it has become completely unreliable. All things considered, it isn't too bad. A battery and a starter (both of them were past the end of their projected service life).

    Healthy competition is always welcome:D, I'm sure it's up to Andrew though, but it's hard competing when winter creates an unfair advantage. We'd have to report daily temps to make it fair...70F and lower gets additional percentage points, while 71F and higher loses percentage points? :p. OK so maybe not, but however it goes it goes. Increase the fun factor!

    Here's my climate:

    I'd use an average of these "normal" temperatures for the months of the challenge. For a Jan-Feb-Mar challenge, using the link above, I have average highs of 57,63,70 and lows of 34,37,44. Average all those to give 51 degrees. If everyone who wanted a winter handicap used this, we'd have a somewhat level playing field.

    Then comes the question of how much adjustment to make, and against what control.

    That would certainly be a lot of work. I guess that's why it's up to you ;). I would say let the majority of the competitors decide what should be done, possibly a thread for suggestions. Find the %age mpg drop for each 10 degrees in weather change like you and Jason posted. Modifications and a ton of other factors could make a messy comparison though. There would have to be some kind of controlled experiment to determine the amt...if the figures aren't already available on the web.

    I wouldn't mind seeing sean join in with a winter handicap. We can make a special division for him and larry the (engineer):p:D

    Tank right now is sitting at 39.7 mpg@ 229 miles on odo. sitting just under half tank on the dash. I'll have one more fill for this challenge.

    I just noticed that my son never entered a vehicle in this challenge. He will be filling in the next day or two but I will leave it up to Andrew as to whether or not he can enter his vehicle and tanks at such a late date. At any rate, I'll make sure he gets a vehicle entered for the next session.

    I will be filling up by this weekend sometime. I just dropped to 4 pips today and with the poor weather forecasted for the the weekend, I don't want to be caught with a low tank. If everything goes well, I may be an "engineer" by around the end of the year.;)

    :woot: Sounds like a great time to be had. :D

    Colder temps this morning making it rough on the Beast
    to school for drop off and then to work>
    - 11.7 / 1.4 miles (14F NW@13 wind didn't help either, head wind)
    - 18.6 / 12.3 miles

    home (a little later than usually, work:()>
    - 20.2 / 13.3 miles (24F NE@5)

    it doesn't help that it take almost half the distance home to get fully warmed up:eek::(

    daily avg - 19.0 / 27.0 miles
    tank is still above F and 31.0 miles on the ODO.

    Whine, whine, whine. Lots of people complaining about cold weather, but I'm still not seeing any real competition for last place. ;) My next tank is on track to be below EPA.
