What's the harm in a rank number greater than 20? Look at the MLB batting average rank order - it goes well past 500...
Here's a 59.x reading from the latest tank. fwiw after the prior tank is was about 40F while filling up and I only got 8.1 gallons in, this time it was 60F and I got 8.5 gallons in. Maybe I could have squeezed more in by going past the first click but I don't want to stretch the bladder so I'm limited to about 8.5 x MPG for my tank for now. Maybe in the summer I can get a 9+ gallon fill up.
Top 20 works well, as it encourages people who's commute or terrain isn't ideal to try to get their best MPG because they still have a shot of getting in (assuming they can get up to 60 mpg). I know, for me, that it is "game on" next summer. I want to get back into the top 10.
If I lived closer I would thwart your efforts by letting air out of your tires every night. *evil grin*
On cleanmpg.com mileage logs there's a top 50/top 100/all - but they don't differentiate from marathlon fuel efficiency and daily driving fuel efficiency so the top 50 is mainly marathlon results by the expert/elite hypermilers. Fuelly doesn't sort the individual car-driver pair results by fuel efficiency but they provide a statistical distribution chart of the overall results. On Fuelly.com which has 1678 Prii registered, the top 1% is achieving +61 mpg and the top 2% is achieving for MPG is 59 mpg or over. The top 5% cut off would about 56 mpg and the top 10% cut off would be about 54 mpg overall. The 3rd gen Prius (2010-2013) fuel efficiency is averaging about 48 mpg - ISTM that getting 10 mpg more (20% more) than the approximating average/mean is statistically meaningful benchmark but being just 6 mpg more than the average (slighty above 10% better MPG than the average) put the driver in the top 10% wrt to FE.
First, thanks to all for the warm welcome. Grateful to be allowed to post in a GenIII forum with the kind of real-world strivers which I suppose myself to be. Mr. Walter Lee among the rest of you seem to always touch on points of interest and education for me. I filled this morning (Big Day!) for only the 4th time since buying my gen2. Hit 600 miles on the dot and kept my indicated 67.5. First click at 9.39 but I have a system for fill ups been using forever in which I pump beyond to the nearest even buck. I figure makes my bank statements a little clearer and reduces likelyhood of underfill. So my calculated was down under 64, a bigger discrepancy than prior tanks. Yes I will jump on Fuelly soon! Anyway y'all have motivated me to couple goals. 1. 700 mile tank. Shouldn't be difficult despite guess gage blinking at 524 miles! 2. 70mpg tank. For this I'm going to need your help! I've got admittedly some near ideal conditions to make this happen. A commute of enough length to get warmed up, on smooth wide roads at good times of the day to avoid heavier traffic, warm temps thru the year, a 2nd car I prefer to run errands with, and so on... Stay tuned This is what gives me hope!!
Please do remember that if you are driving a second generation Prius manufactured for the US, you will have a "bladder" in your gas tank to reduce vapor emissions. This means that you never TRULY know how much usable gas you have in your tank (because the bladder is flexible and in colder weather it won't flex as much, meaning you won't get as much gas in the tank as you'd like....tendency to underfill). The gas gauge for the Gen II is jokingly referred to as a "guess gauge" because of this bladder (and it is a guess as to how many miles you can drive with a flashing pip). Many a Gen II driver has found out (to their chagrine) about this after they have run out of gas. If you search the Gen II forums, you'll find many threads (search bladder, guess gauge, running out of gas). Still, congrats and great job on this tank!
Outstanding job for a new owner! You've really absorbed lots of useful information about the car and put it into practice in less time than most of us here. It took me months to digest and get used to hypermiling the prius. Just a pre-caution, make sure you consistently monitor or calculate your estimated fuel left on the tank in relation to your tank mpg readout especially towards the last and blinking pip as it's volatile. I hope you've put in more than 10 gallons on your last fill-up if you're aiming for 700@70.
I love this car So much because it so responsive.... to informed driving! So pardonez-moi the boring biography but the hypermiling ethos is sorta intuitive to me - well with a huge thanks to priuschat and cleanmpg - but I'm 60 yrs of age with a crapload of driving experience underpinned by the 2 and a half years I spent as a test driver for Ethyl Corp the folks who used to put Lead in our gasoline - in the early-mid 70s while I was a college student in my hometown of Detroit. Yes I lived was raised on the Detroit side of 8 Mile went to high school at Cass Tech downtown and finally worked for my family's "company" Ford Motor Company. Booked out for Florida 1982. Still Love Michigan and Detroit. But I drive a Toyota and Honda Odyssey with 275000 trouble and bad-surprise-free miles on it. Cant lie friends. Anyway the test driving - 8 hrs daily over suburban and highway dyes in Wide variety of vehicles
Routes I meant to say. Gave me and buds I drove with time - on the midnite shift - to figure out light timing coasting driving with no brakes... 500000 thousand miles per year. So that's why its intuitive. And yet I learnedr All about This car plus some things I never satisfactorily answered for myself like DWL right here and recently and every day I start my car up. I love my car something fierce because nothing has ever had the wherewithal to help me - uh - pilot like this before.
Well, I'm proud to say I made the top 20 yesterday. 1) Time of year: Late Fall here in Northwest Florida 2) Tires: standard OEM with pressure of 36/34 3) Car: 2012 Classic Prius. 7800 miles on ODO. 4) Techniques: I'm just your typical hypermiler. I used to own a 2006 and it was a lot easier to use the pulse and glide method than my 2012. Nevertheless, I do try to emulate that technique in my newer Prii. I have used ethanol free gas the last few tanks and so I have noticed an increase in MPG of about 2. During this stretch, we had a few days of colder weather so I'm sure I could have gotten it a bit higher with all warmer weather (average weather of around 64 degrees) My goal is the 700 mile club. Last month I acheived 692 miles but was afraid to run out of gas (no gas can in the back). Anyway, I love my Prius and am glad for this community. Ken
Nope, gotta beat 59.6 at the moment to get 20th and anyday now 20th place will be 61.9. I figure I'll be bumped off the bottom of the list shortly. I may not be back on the list for many months after that, might get over 65 on a tank in the warm weather. I might even have to wait until I get new spark plugs (I'm at 99,000 miles on the factory plugs and I'm not sure how much of my MPG is the weather, the tires, or the plugs). Come spring if the MPGs don't pick up like I expect I'll put new plugs in.
I'll add a little dilemma to this thread. What if the same person (I'm not naming any names) posts two or more tanks that meet the requirements? Both tanks would be among the top 20. Are we tracking the top 20 tanks or the top 20 persons with exceptional tanks?
