    Some people's commutes don't really allow for that kind of fuel economy. Tell us about your commute and we may be able to suggest some tips.

    I go to work seven days a week and travel about 10 miles each way on the north side of Chicago. Most of my trip is smooth roads with a few small hills. I can travel either on the highway about 55mph or on main roads about 30 -45 mph. I should hit my first 600 mile tank this year with the monitor reading out 63.5mpg in a week which I know is easy now to reach this number in the spring and summer time. What do you suggest to do in order to hit this 700mile tank? I know it is not impossible to hit this mark with a little more knowledge : ) thanks for your help!

    If it's roughly the same mileage definitely take the slower roads (unless there are a ton of stoplights). 30 and 35 mph roads are perfect for pulse and glide. I assume you are familiar with this technique? It's essential for high fuel economy.
    Technically if you wanted to push your tank a bit you can already hit 700 miles with at or anything above your current of around 64 mpg.
    The very best MPG's will come when the temps are in the 80's and you don't mind not running your AC. :)

    Thanks for helping me out and I'll try the side roads and see if it helps! (y) I dont know if I am going to get 600mile on this tank due to the weather dropping from 75 to 32 in two days :( But I am sure to remember that with 64mpg monitor reading I can make it happen to reach 700 mile tank. Also the most I went with my car past the tank reading 0 miles left was about 40miles...how much more can I push the envelope if I am getting about 64mpg reading??
    Thanks markabele!!!

    So you definitely pulse and glide already?

    Also, do you reset a tripometer for each tank? If so, you can very safely go to 10 times whatever your MPG for that tank is. For example if your MPG for that tank is 64, you can very safely go 640 miles on that tank. If you really want to push it, you should be able to even do 11 times the MPG number on a tank. By that methodology you only need 63.6 MPG on a tank to hit 700.

    Yes I can pulse and glide I think lol can you explain just to make sure?

    I do reset the tripometer after every tank! Let me get this straight if the monitor is reading 64mpg I can safely go 640miles on that tank is that correct? 64mpg X 10gallons = 640mile tank....but that is 60miles away from 700mile tank...if I go 64mpg X 11 gallons = 704 mile tank but how can I be sure if I have enough fuel in the car if when I fill up I just let it stop after the first click to make sure its a accurate reading? I know its a 11.9 gallon tank but how many gallons do I have if I let the pump stop after the first click?

    Thanks for your help again markabele!

    Just remember that if you hit bad weather or some other anomaly that drops your current mpg, like say 35 mpg for the last 75 miles. You will need to adjust for this big drop when figuring your DTE. You need to be consistent at 64 mpg for the whole tank.

    Correct. Just let it stop after first click. I wouldn't recommend it as a regular practice, but maybe go an extra click or two if you want to make sure you have plenty of gas for this attempt.

    Pulse and Glide can best be shown by watching this video...

    Thanks for the link and I will give it my all to hit the 700 mile tank. Report back in a month to see if I made it lol

    I've run out of gas over 30 times in our 2003 Prius and 7 times in our 2010 Prius. The Prius doesn't 'putter' but switches to traction battery for about a mile or so . . . depending upon SOC and driving style. I use the last of the traction battery power to reach a safe place to park.

    What symptom caused the halt?

    The first set were to drain the tank for gasoline quality study. The 2010 was initially the same idea for an E85 study only to discover the control laws hide the moment the gas is finally gone. Later I found that the power flow arrows go away.

    I did my E85 study and found E50 works fine without a check engine light. E85 works but throws a safe to ignore check engine light.

    You can tell when its traction battery only because

    1) the ICE is silent
    2) the ICE-electric motor-battery diagram only shows arrows from the battery to the electric motor.

    I have had a couple of fill ups at 600 miles where I only used around 10 gallons, so I could most likely do it, but I dont think I will push my luck ;)

    I made it, I am in! :D I am a courier, and got lots of city runs dispatched to me this week , that really helps my mpg with the slower average speeds, so I decided to go for it! :) No real techniques besides light footing it, eco mode, and having a scan gauge II dialed in within .1 of a gallon, that gave me confidence that I could drive on, even though my low fuel bar started blinking at 570 miles, and my indicator said 0 miles left at 600 lol! Other than that, it is all the car, these cars are awesome efficient, glad I finally bought one after thinking about it, like, too long ;) The scan gauge had me at 11.2 gallons burned and 43 miles to go when I finally got to a filling station at 720 miles, and it ended up being 11.1! no I am not gonna try for 800 lol :D
