    This is not a reward for having the best commute. This list is meant to recognize those individuals who can push the car to the max and have the endurance to keep pushing it for 500+miles. Most of the Eco challenges are performed over short distances of less than 30 miles. What we are doing is much much more difficult. :)

    How's that different list for different models thing coming? I didn't really hear anyone on here that was really against it, only a ton for.

    At present, in its un-updated state, 15 genIII, 3 prius c, and 2 genII are on the list.
    I don't see the need for the various lists to be a pressing one as yet. It's F8L's thread, so my suggestion is to let him do things at is own pace and through his own good judgment. :)

    I've got my new wheels and tires:
    IMG_3597 (900x530).jpg

    Drag DR9 15 x 6.5, Pirelli P4 185/65. I ordered 185/60, and when I checked, found these installed. The 60's would have decreased the rolling circumference from stock 16.59 mm ( -.9%), but these add 39.21 mm (+ 2.14 %). Stock on the c with steel wheels - 15 x 5 and 175/65. I found it very difficult to locate alloy wheels that mirrored the stock size and were reasonably priced. I was out the door under $700 for the whole shebang.

    This is a softer ride with increased stability while cornering. I was running 39/37 in the old tires at the end, and 40/38 in these. I expect a significant difference in MPG's, so I'm glad I did the last little run at the title when I did. I detect a resistance to rolling now. :)

    Update: I was requested to fill out an online questionnaire regarding my experience at Discount Tire. I gave them pretty good marks but added that they had installed a different tire from what was ordered. They called to ask me to come in and make the switch to the 185/60s, so that's what I'm running now.

    I'm not saying get rid of this list, just do other top 10's for each model. I think there would be more C's if it was listed in their own forum and their was more competition over there. Also, don't you think the V's deserve their own list?

    Dear F8l,
    Yes I am keeping 35psi. My local area sometimes gets quite a huge rain that floods everywhere, so high tire pressure could lose the grips on it and thus is a dangerous practice, I think.

    I totally agree. Getting >99mpg for 10 miles is nothing. I love it not because of the high mpg itself, but it is a real way for reducing our footprints on our Earth.

    I feel like such an idiot. I just we nt out to see how to implement Vincent's method for calculating MPG above 99.9.
    10 mile runs notwithstanding, I ran 10 miles anyway. I set fuel cost at $9.99. (Vincent's idea of $10 0r $100 doesn't fly because it will only go to $9.99. :)) They obviously weren't planning ahead for the coming idiocies of cap and trade.
    IMG_3599 (530x413).jpg
    One can see that using the computer's calculation and a little math yields a result in excess of 108 MPG. Thank you so much, Vincent. If I had been smart enough the figger this out for myself, there would be less doubt about what I really accomplished. Oh, well. Live and learn. If one adds the 2.14% for the increase in rolling circumference o the new tires, it would be near 111 MPG.

    But driving for 500 miles just to get on a list is not reducing one's footprint on earth. Should I find a 50 mile stretch where the slope is mostly downward and get a tow truck to bring me back to the starting point 9 times so I can really crunch the list?

    If you want to leave a smaller footprint, buy smaller shoes. If you want to leave tire tracks, drive.
    Yes, but don't forget to tip the driver. (()f the truck.)

    The list is updated.

    I apologize to ufourya for not updating his record in a timely manner. I got really busy and simply forgot. I used his 99.9mpg number at his request despite us both knowing he was much higher than that. Without careful recordkeeping on fuel input price it is difficult to know how your exact FE is. With this in mind. If you are attempting a 100mpg+ tank please record your fuel input price and post that information as well. I know we are all honest folk but lurkers may not know us and we want our records to be a credible as possible. Remember, this is for posterity. We are the ones who "go before". ;)

    It's not but the tiny amount of fuel used by the competitors will likely be mitigated and much more by those who now know what their cars are capable of and who will strive for better FE even though they are not trying to compete with anyone but themselves.

    As for towing cars back and forth up a hill. That would be dishonest. We don't work that way. You know that, bro. :)

    Dear F8L, that's exactly what I meant. Thank you

  16. It's a Top 20 list, that's what it's there for. At some point someone has to push the envelope.

    Personally, I'd be content with getting spot #20 by going on practical trips (e.g. to work, supermarket, for fun), rather than go for #1 just because I have that much free time... (plus someone else will try to beat that #1, and then someone else again, etc.)


    As it stands, I do too many 1-mile trips so my avg. fuel economy hovers around 50 mpg...might take me a while to get on any sort of "Top" list here (n)

    If information is available from those who made it on the list, maybe put a short description/codes next to the entry about the technique used or any special circumstances/handicaps that led to his record eg. (P&G, DWB, city 30%, EBH, 17s, drafting, winter, hilly, etc). That way, everyone will be able to get an insight behind the successful entry in summarized form and learn what to do or what not to do. It's a lot of work for F8L but it will be a valuable source of information for everyone on what really works.

    There's no shortage of write-ups about how to get good/better mileage in a Prius. There's no reason to attempt to recreate them all here. Here's a link that seems pretty good.

    Advanced Prius Mileage Tips


    Here's my list:
    • I do not take the straight-shot to work because it's a four-lane highway of competitive commuting. I take a slightly longer, slower route through nature preserves and past schools. Instead of 45 - 50 mph speed limits, I cruise along in 35 - 40 mph zones which allows me to hypermile without impeding traffic flow. Also, it's much more peaceful for me.
    • I keep my tires slightly over-inflated and monitor them at least monthly.
    • Brisk acceleration. Don't nurse it up to speed but don't stomp on it either. Accelerate like you're in a hurry but not like you're racing. Once up to speed, ease back and relax.
    • Coast to Red lights. How stupid are those people who race to red lights only to stomp on their brakes. Then they have to dead-stop accelerate. Wasteful.
    • Drive with this in mind: every time you hit your brakes, throw a dime out your window. Every time you come to a complete stop, throw a quarter. I challenge you to track your expenses for each trip for a week. Then make it a game to save as much money as possible.
    • Learn from your commute. If you're like me you drive the same route ~250 days per year, twice a day, for many years. If you haven't figured out the traffic light patterns yet, you're either not paying attention or brain-dead.
    • Barring traffic, if you have to brake going into a turn, you didn't plan enough. I can safely make a left turn at 30 mph. The goal, then, is to cruise down to 30 mph before I get to the intersection and simply make the turn without braking.
    • No matter how many cars speed past you (some rudely) you are still making progress. It's human nature to think that getting passed by cars is some sort of loss. In the grand scheme of things, you are driving exactly the way you would be driving even if those cars didn't exist. Don't let them get to you.
    • Hypermiling is supposed to be a game. A fun game. When it stops being fun, you're done.
    ABOVE ALL ELSE: DO NOT IMPEDE TRAFFIC, BE RESPECTFUL OF OTHERS' DESIRE TO NOT FOLLOW AN nice person, AND ALWAYS(!) OBEY THE LAW.

    Great list! The only thing I would like to add to your quote above is:
    • Hypermiling is supposed to be a game. A fun game, that literally pays dividends. When it stops being fun, you're done.
