    Very well done Donee !
    I figure you have about two months to get the hell out of Chicago, or your MPG's are gonna get deep sixed.

    You hear me ? :)

    Hi All,

    Thanks for the compliments. It takes mostly dry weather in the mid to high 80s, carpooling rides to lunch with co-workers AND lucky timing at the lights. This time I did it without any instrumentation, but with the knowledge (primarily peddle push levels learned with the instrumentation). I did cheat a little bit, and filled up a day before the tank indicator would have dropped to two bars, because I did not want to take the time to fill up in after any slow rainstorm delayed commute, that was predicted.

    With the Obama bucks flowing into the roads on my various routes, keeping up with the best route for mileage has been a challenge this summer. The day before the fillup, I ran into an unexpected construction project that had only the left turn lane open at a stop light. Allot of people make a left turn there. Due to the cross traffic priority given this light (since the road I was on is very busy) when ever there was a left turner, he would be blocked by oncomming traffic, and so the line of traffic in my direction was backed about 1/2 a mile. This was right after the startup, so the car pretty much completely cooled before I got going again.

    The rainstorms have been occuring just after I get home too. Which was lucky. On a few days I drove the "slot" - rain started at work after leaving work, and at home just as I left work but was over when I got home. On the weather radar my route was a slot in time and space between the rainstorms!

    The cross traffic priority lights that turn for one car, and 30 or 40 cars have to stop are in a few places are a real problem. I have been nailed by them repeatedly in the middle of good glides since filling up, and am at 68.3 mpg for the first couple of days consequently. They really need to put a long delay timer on those things when they are on heavily travelled secondary roads.

    I can usually stay above 60 mpg till it gets below freezing in the morning. Which can be as early as the end of October, but as late as the end of December.

    My original post on this thread indicates the first time I achieved 70+ mpg for a tank was in the first week of September - about a month from now.

    If weather averages out, we may not see cold weather till late this year - hope hope. We have had a cooler than average summer as aPriori points out, so we may have a warmer than average fall. So, that would mean 60+ mpg tanks till the end of the year !!!

    Hi All,

    New record. 70.7 mpg Gen II MFD mileage, although it was quite hot today, and the tank took allot of fuel so the fillup mileage was 66.6. 589.3 miles. Could have gone another day, but my rules for this, is on the trip home after the tank drops to two pips, I fuel up. It dropped about half way home/to gas station.

    In Chicagoland? I'll be darned. How do you do it? I never get more than 48 unless I'm on the highway

    Hi All,

    And twice in one Summer! Just finished another 70+ tank, and a yet another new record (!) - 70.9 mpg indicated on the Gen II MFD. 595.9 miles, 8.642 gallons pumped, which works out to 69.0 mpg. Temp today was similar to the last fillup.

    Can I do it a third time this summer? Stay Tuned to this channel !
