    Trying to find water leaks is sometimes easy, and sometimes not.;)
    last night:
    - 60.5 / 13.0 miles (35F NW@10)
    FCD = 51.2 (+0.2)

    this morning with school drop off and frost:
    - 46.1 / 13.1 miles (19F SW@4) with frost forming on the inside of the windshield so had to use heat and keep the car on so less P&G's
    FCD = 51.0 (-0.2)

    Tank:
    7.65 gals converted
    382.9 miles (eked over 50 calculated now :D)

    Today , 27 deg F , wind W 7. 34.3 miles , 63.0 *.93 = 58.59 MPG. Made it to work with two pips left , this means I won't need to fill up until Sat AM. Tank is at 503.4 miles , 62.7 *.93 = 58.31 MPG.
    If I don't work Saturday , this tank could last until Mon AM. I'm never sure if I'm going to be invited to the Saturday morning "party" , they don't let us know until around lunchtime Friday. But last year , I worked 45 Saturdays.

    I decided to buy the Ultragauge next month, and I'm pretty excited to get my hands on it. P&G down the highway has been working just fine. Traffic has been light enough that I can pulse to 55 and glide to 45 (55 mph zone) without backing up traffic. The only people who get mad are those who aren't paying attention and end up on my bumper when the LH lane is wide open. I don't feel bad for them.

    Odd thing about this week is it looks like my fuel gauge has pooped out. That or I'm getting about 120 mpg. I'm at 180 miles on the tank and haven't lost a pip. There's a little part of me that wants to believe in 120 mpg out of a Yaris. :D It's just odd coincidence that my first full effort at advanced hypermiling techniques and my fuel gauge freaks out. Anyone else have issues with this?

    Haven't seen anything like that with the fuel gauge.

    We dropped down to frosty temps overnight.
    51.3 / 5.3 - home
    36.3 / 0.6 - to a nearby school open house, to see if we want to transfer there.
    41.0 / 0.6 - home

    48.7 / 10 - to school this morning
    55.9 /7.5 - work

    Tank steady 50.2 / 304, nearly down to 1/2.

    TM, did you add a little extra in the fill so that you had more gas in the filler pipe? I have seen close to 120 miles before my needle will move past the full line. But mine is an analog needle so I seen that it is moving down toward the full line. My wifes Sonata is a digital one and usually loses the first pip with in 5-30 miles. Depending on the fill. Getting the UG will help refine your Pulsing technique. If traffic allows you want want o go to 40 for you low end. The longer you have to recover from your pulse the more MPG you will be able to accumulate over the trip.

    last night:
    - 59.1 / 13.0 miles (43F W@10)
    FCD = 51.2 (+0.2)

    this morning:
    - 48.8 / 13.1 miles (28F SE@4)
    FCD = 51.1 (-0.1)

    Tank:
    8.15 gals converted
    408.5 miles
    F____|___>**E (just below about 1/4 a tank.)

    I filled to the first shutoff. It was a different station than I normally use, so it might have added more than I'm used to. I made it to 82 miles on the last tank before losing the first pip, which was a record by 20 miles... 180 miles is uncharted territory.

    Is the long recovery true across all ranges? Meaning that a coast to 0 would be ideal?

    Coasting is the magic part of p&g. Not all the way to zero, because the restart from zero to 20 mph is a killer. All cars are inefficient in low gear at low speeds. You have a 5-speed? Anything you can do in 4th and 5th gear is good, 3rd is ok, 1st and 2nd are bad. I'm usually into 3rd before I've crossed the intersection and don't touch the low gears again unless I've stopped.

    Generally, I like a speed range of 15-20 mph for p&g. 20 mph to 40 is just about the best, 25-45 is nearly as good, and then it goes down as you get faster. If your gear ratios are better than mine (lower rpm, likely they are) then you can push a little higher before the engine is revving too high. Even with good gears aerodynamics take over and hurt high speeds on the highway.

    I agree, a 15 to 20mph delta is probably the best balance when doing P&G.

    Needed to go to physio again early Saturday morning so took a gallon of gas with me just in case, 42°F, raining. 2 miles from home FCD bleeped and told me I had no gas and last pip on the digital fuel gauge started flashing red :rolleyes: so I carried on of course :p :

    As it turned out , I didn't work Saturday. I wasn't supposed to see Cindi until Sunday for her Super Bowl party , but her mother wasn't feeling well enough to go their play at the beautiful Paramount Theater Sat night , so she invited me. I had to fill up first. And since this is the Monday AM after Super Bowl Sunday , of course I can't find my gas receipt ( I'm sure it's in the car). I will have to go back to the car after coffee and check. I think it was about 534,9.2gallons. I will get the numbers and document it here, because................ where else ? Fuelly ?

    Okay, got my numbers now. 541.1 miles / 9.236 gallons = 58.59 MPG. Could have been much worse. Fcd showed 62.5 MPG , so over-report is about 6.7%.
