I'm in LA, so I'm doing a combo of every kind of driving you can do everyday. A mix of highway and city. Stop and go traffic and high speeds. Strong accelerations and sudden stops. I'm been using Eco, PWR, and normal modes depending on the driving situation. I live in a canyon so I'm up and down steep grades everyday. And I've been using AC much of the time. With all this, I'm not surprised at the mileage, but now that I'm getting a better feel for the car, I'm hoping to crack 50 with this next tank.

On my way to the gas station yesterday I hit a new best -- 63 mpg!

Except when I switch to pwr mode, I'm consistently topping 50 mpg. Think I'm going to do much better on this second tank.

After 600 miles, I'm averaging 57.4 MPG.

I am very impressed with this total considering my commute is only 6 miles each way, and I have to climb some pretty steep hills.

So far on my second tank (70 miles) I am averaging 62.3 MPG.

Guys, it's it me or what if I do the simple math, if people are getting as good as 55MPG, then 55 X 11 gallons = 600 miles per tank with about .9 gallon to spare. What is the expected range on a tank before you will run out of gas?

Danny mention that he only did 501 miles and he was happy, shouldn't we expect to have at least every tank hit over 500 miles before filling up with at least 1 or more gallon to spare?

Just questions from a new Prius owner.

the bladder induced fear of running out and the resultant habit (at least for me) of filling up as soon as 3 pips turns to two (or sooner) will be overcome over time as people report their experience.

i should get my 2010 IV solar this week (its in "F" status). I have 4.5 years of the same commute in my gen 1. Last summer i averaged 50.0 MFD. I will report here after a few tanks on the same commute. I am confident any improvement will be objective and real when i have several tanks experience.

btw - when i got the 02 in 05, my first tanks were very low 40s until i learned

Exactly, I have that exact bladder-induced fear. I'm not sure how far I could have pushed it, but on this tank I'll get a better feel for the actual cruising range. After I filled up it said something like 640 miles DTE, and now averaging around 56.5 it's saying 400 DTE with 140 miles on the trip ODO.

well on my tank before the current one. i had gone to blinking bar at around 470 miles (give or take) went to zero DTE at around 550 miles... filled up at 614 miles. so there appears to be a minimum of 1½ gallons (actually bob and ken figured nearly 2 gallons but i fudging on the safe side. ken i think said just over 7 liters so kinda spliting the difference a bit on the low side)

so basically i went over 100 miles after the blinker. bob actually ran it dry, did around 120 miles or... so looks like the gauge is still not going to be accurate if you really want a good gauge to empty. Toyota has made sure that when the car says "empty" there will still be enough gas to get to a station.

all in all, the only real way to know how far you can drive is simply get to know your car.

Added side benefit. It's a safer way to drive, especially with children inside.

Generally speaking it is better to lift off the throttle sooner then glide to the stop sign than it is to stay on the throttle for longer and then have to use the brakes to slow down quickly. On country roads you can sometimes go almost a 1/4mile or more just gliding which uses no fuel OR battery power. Anytime you are using battery power means you will have to regnerate it and succumb to energy transfer losses. In your case by braking early to regen battery power you stayed on the throttle too long and thus you used fuel to generate the power for the battery and you had energy conversion losses. Gliding is your best friend.

Also...as long as it's safe and legal ...try not to come to a dead stop - ever. Having to overcome the inertia of a 3000 lb block of steel, glass and rubber at rest requires a lot of energy, Newton's 1st Law.

• Try to time stop lights such that you don't actually have to stop.
• If a traffic stoppage up ahead may breakup then let off the go-pedal earlier so that you glide up to the stoppage and hopefully don't actually have to stop.
• California right hand turns where legal and safe.
• Anticipate traffic patterns ( makes for much safer driving as well ).

"try not to come to a dead stop - ever". It's not legal to do that at stop signs, and impossible with traffic lights. I thought that when you accelerate from a dead stop you use EV as long as you have a very light foot. So much to learn and still my dealership can't deliver. Thanks to all for so much information.

I've got almost 900 miles on mine now. Abput 625 highway and the rest city.

Total MPG to date is not as impressive as many but it is better than my 2006 was at 46.7 mpg.

On the road trip this weekend which was over 600 miles I got an impressive 50.2! I think as things break in I will see an increase in my overall mpg though.
