    Reset a trip meter. Drive and keep track on that meter. When mileage travelled equals posted MPG, post a photo. I'll start the car rolling. (My calculated MPG is consistantly about 2 MPG less than the indicated figure, so this is just for fun and kept as easy as possible.)

    Don't do anything dangerous or stupid to snap your photo - plan ahead.

    If you are going from an elevation of say 2,000 feet to sea level one gallon will
    take you a lot further than on a straight level road with no wind and/or elevation
    change. So, the one gallon used would need to be consistent.

    The best way would be a round trip from your residence to a distant point, than drive back
    and than calculated mpg's.

    You could also load your car on a flatbed truck, take it up Pike's Peak and coast down. Then repeat.

    This is supposed to be fun.

    For the record, I live in central Texas with gently rolling hills. I left home and ended up close to home (within 2 miles) when the photo was snapped. One would need better computational skills than I possess to start and end exactly the same point when the MPG figure matches the mileage travelled.

    How can one gallon be more consistent than one gallon?

    Please post an entry. You should be able to easily best my meager effort. :)

    Dang, I didn't take a picture at the 1 gallon mark, but waited until past 100 miles:

    This was a year ago in my 2010.

    You came closer than I did. I forgot to take a pic until after 200miles and 2.4ga. :( LOL [​IMG] ok ok I'll stick to the rules of the thread and try again but I doubt I can top ufourya unless I go pulse & gliding.

    I did it with a higher average speed (42 vs 34 mph). But from your distance, I'll bet you had a shallower average slope. Since Ufourya ended within 2 miles of the start, he probably had a shallower slope too.
    My photo album does show a round trip, cold start, exactly zero net elevation change (despite 3400 feet gross climb), of 72.1 mpg over 71.6 miles, or 0.993 gallon. That was just a month after getting a hybrid. I should be able to do better now, especially with a hot start, but probably can't reach Ufourya's figure without some elevation change.

    About 40 of those 233 miles was my normal commute from 1,200 to 200ft over the first 12 miles then a gradual decline from 200ft to 20ft for the remaining 28miles. The remaining miles were spent pulsing and gliding for 6hrs like an idiot. 25mph to 41mph over and over and over......

    ^^ I haven't yet had the right situation, lack of traffic, and patience for the really long P&G. So I reset the trip meter at Chinook Pass (elevation 5430) and headed towards town. Picture elevation about 500 feet, and a big chunk of that elevation was wasted in B-mode compression braking. There must be better roads somewhere that make better use of the gravitational potential.

    Didn't lose the first pip on this tank until 146 miles. Then I had to go to work and watch the MPGs drop and drop and drop...

    That's really impressive! Is this the start of your 800 or 900 mile tank?

    No, this tank is already down to 67 MPG due to the nature of the car's use in business.

    First one decides to do it and then one uses hypermiling techniques on an appropriate terrain at an appropriate tme until it is done. All the information is available on Prius chat and cleanmpg.com.

    Have you been watching the 99.9+ thread? This mpg is within a hair of qualifying, and your distance would easily own the current title.

    Something tells me F8L may have just clained the lead.

    That 98.7 over 98.7 is truly impressive. That had to have been pretty boring. :p

    Seriously, I'm very impressed. It's one thing to go out for 10min and post a high number but to drive for an hour+ and maintain essentially 100mpg is dedication.

    I blew the logistics and failed to snap a shot at 99.9/99.9, but it's pretty close.
