    You do know that taking two tanks to do it doesn't count right?

    Anyways, GL to you. It's too hilly around here to P&G. I'd be in P for .5 miles and G for like .1. I don't think that'd work too well.

    Also, on the tank I'm on right now I'm not even bothering to look at the consumption screen till I fill up. I'm still hypermiling it, I just not watching it. The one time I looked at it, more to see if my engine was still on while I was coasting, I thought I caught a a glimpse of 65.x MPG, but I'll only know once I fill up at 500 miles.

    I've also decided to fill up at 500 mile intervals now, until I can go 750 miles a tank that is. I feel it's easier to remember a round number. That and it means I'll fill up my tank when I get my oil changed every 7500 miles. I'm weird like that.

    I wish I could get those 70+ MPG tanks, but alas... I don't think my '02 Prius has it in it. Those newer models are just superior.

    Wow! Living in flatland Florida, I am getting 500 to 550 miles or so a tank, but you are awesome! My only question is running on low fuel. Don't you worry about hurting or damaging the fuel injector? I was brought up (or brainwashed) in beliving that running a car too low on gas will really damage the fuel injector. So my 500 to 550 mile tanks are as soon as I start "blinking" or before due to that train of though. Any comments?

    Could you answer the following questions?

    1) Do you have an EBH (Engine Block Heater) If yes, do you use it everyday?

    2) Do you have an EV switch installed? If yes, how do you use it.

    3) Do you have a Scanguage or CanView or other device? If yes, how do you use it?

    4) What is the average length of your trips.

    5) What do you do in the first 5 minutes to help with the warm up cycle.

    6) Could you briefly describe what your pulse technique is. Specifically how do you set your pulse.

    7) Anything else that gets you this MPG.

    Thanks

    Congrats. That must be a North American all time record.

    How many gallons did you squeeze into the tank after completing that run?

    I share your frustrations pingman - I have a similar commute.

    I only have 12k on the clock so maybe the ICE is not broken in yet but with all the P&G I can , no arrows, using EV as much as possible, I'm on 69.8 UKmpg at the moment.
    Although I get close I've never had a 600mpg tank yet.

    There is another thread on PC at the moment about looking at mpg not as how many mpg you can do but how many gallons you consume say, in a month. Its more realistic I'm thinking.
    I fill up when I get to the last pip and although UK models don't have the bladder I put in around 9.5 UK gallons

    I have to say that I find what VABeachPrius is doing is quite frankly astonishing -does NASA know :lol: .
    I'm so impressed - but he must have, not ideal, but PERFECT conditions.
    I guess they are things like long flats, few lights, good temperatures, little traffic, no tailgaters, no A/C.
    Am I missing anything ?

    congrats beach, if you can do that where I live (British Columbia Canada) i'll give you 100 bucks. I have way too many one laners + aggressive drivers its just a fear for my life when I try to coast. I wish the goverement would build roads made just for hypermiling!

    1. Yes. I use it each morning. I do not have a plug at work.
    2. No.
    3. No.
    4. 20 miles
    5. Try not to use any energy from the battery. Glide with N to a stop while trying to keep the impg as high as possible. In the summer my first 5 minutes are between 25-35 mpg.
    6. I pulse to 31ish mph and coast without using EV (as best I can) to 22 mph and repeat.
    7. Average speed 20 mph. If you dirve slower, the car will do better. Taking back roads gets me to work at almost the same amount of time. There is a lot of traffic on the roadways when I leave for work. The back roads are almost empty for me.

    I am at 200ish miles at 93.2 mpg displayed. I have been "driving" a speacial course on occasion this tank to practice for real world driving.

    Chris, how do you manage to only get 25-35 in summer with the block heater? You should be easy north of 45-50 MPG. Maybe it's that warm-up routine you do, might not be the best for early MPG.

    Wayne,

    In the morning, I have 0.5 miles of neighborhood driving. Then its 1.5 miles of 45 mph driving that is on a two lane road. There is always traffic and out of courtesy I am forced to drive 45-50 mph. If there is no traffic I can P&G at the very end and glide to a stop at the stop sign. With not traffic, I can usually hit 50 mpg during the first 5 minutes.

    Suggestions?

    Thank you for responding. I have not heard of pulse and glide at those speeds before. I had always heard of pulse and glide at 40 and 30. I will try it at the slower speeds.

    I have learned a lot it the 3 months that I have had the pri. I am now able to consistently get 71-72 MPG on my commute to work and back. I am hoping to refine it even more and approach 80 with the addition of an EBH and refining my techniques and route selection.

    My circumstance is different here in the Cincinnati area then in Virginia Beach. I must navigate several 500 ft. elevation change hills on my way to and from work. Also there is one bridge that goes over the river on my commute that is interstate. If I don't use that bridge I have a 5 mile detour to go around. Out of my driveway I have to go up a steep 220 ft. elevation change hill right as I exit the driveway. Almost every time I have a 3 bar green or 2 bar purple battery when I get to the top of that hill. Needless to say it has been a learning experience. Many may have similar situations as I do. I am trying to pick people brains and use the techniques that work for my situation.

    Anyway thanks for the info.

    P.S. My wife has always been after me to "slow down" and smell the roses. She has finally got her wish. I think she may be having second thoughts.

    Chris, I also find it interesting that your pulses are at such a low speed. Are you consistantly able to get into stealth when you only speed up to 31mph? I often find that unless I hit 35mph (minimum) before feathering that the ICE will continue to run. If one used and EV button I could see a pulse to that low of a speed working.

    If your commute is 20miles and your average speed is 20mph....it takes you an hour each way? You could beat that on a bike! (not that I would/could do that). I think I'm just going to have to be satisfied with highs of around 65-70mpg and average speed closer to 30mph for my 15 mile commute. There's not a lot of traffic, but enough that those speeds just would not be acceptible...I get enough angry looks when I "only" go 39mph in the long 35mph zone that make up about 50% of my route.

    My hats off to you too VABeach!!! that is truly amazing!! and just think, yesterday I was excited about trying to get my first 57 mpg tank........ (actually i still am)

    but you are truly AMAZING !!! :lol: :lol:


    also, I'm with Dr. Fusco, my pulses are usually up to 40 mph then down to 30 (sometimes 28 or 25 traffic allowing).. i also find that when my water temp is around 175 the ICE won't shut off when i feather the pedal, but when the temp gets up to 184-188 it will..... hmmmmmmm.....

    Evan,

    When the car is cold, it will not shut off below 36ish mph. I experience the same phenomenon as you regardless of engine temperaure. I believe after it warms up (Stage 3? or 147C?) I get the engine to start below 36 mph (for example just before I come to a stop at a long light) and then come to a complete stop. The engine will shut off. From there, the engine will stop at any speed below 35 mph when I feather the pedal. If I don't get the car to do this (stop after it is warmed up), then I am forced to go above 35 mph to get the car to shut off during a glide. Make sense?

    Rangerdavid,

    Yes, it takes forever to get places sometimes, but I am on off the deep end as far as MPG. I cannot let go until I get a 99.9 mpg tank. Most of my route is on 35 mph four lane roads.
