Surprisingly, I could not find any threads on Tank MPG for gen 3. Most of what is posted regards to short trip MPGs, which has little value in my opinion, because often circumstances are optimized for enhanced fuel efficiency. So, to address that need, I decided to open this thread. I got impressive 61.1 MPG in my last tank after driving 513 miles! There was just one pip left on the fuel indicator. Weather was mostly dry (rain can have a negative impact) with temperatures between 50's and low 80's (it's the Midwest, what do you expect?). Winds variable but often calm and humidity normal to high (60-90%) (Winds can definitely have an impact but not sure about air density). Driving on ECO mode all the time, AC on 76-78 F for about 50% of the time, 70% city driving. I was consistently getting 57-58 MPG but boosted it up to above 60 by just changing my commute route a little bit. Now, I’m leaving a bit earlier and driving on the back roads.

Indyking, your right, we can all pull miracles out of a hat for short distances. My best tank MPG was 64.3 and over 700 miles. Can't take a pic because I stupidly disconnected my 12V battery when I didn't need to, so all my trip data was lost. Give me a week
Even MPG over a tank is suspect, due to possible variations like overfilling, underfilling, etc. The average MPG over a few thousand miles, always filling with the same gas at the same pump will reduce the impact of those vairations.
Agree, but tank MPG is a lot better than "Hey fools, I got 90MPG", of course, the hidden part is: after a short trip downhill as many are reporting here... Just as a FYI, my lifetime MPG is 57.8 after 3968 miles at 35 MPH. My lifetime is going up after every tank now, it used to be 54!; however, it will start to drive down in few days as my new commute will change to 95% hwy, 5% city driving
Here's why we should all remain skeptical without further evidence: Gen 3 Prius tank capacity: 11.9 gallons Your claimed tank MPG: 64.3 First grade math: 11.9 x 64.3 = 765.17 miles We all know that the MID in gen 3 is too optimistic for their estimated MPG, so adjusting your numbers according to Bob's data: (64.3x 0.85) + 4.3 = 58.955 for calculated "real" MPG. Let's round it up to 59 and redo the math: Gen 3 Prius tank capacity: 11.9 gallons Your claimed tank MPG: 64.3 First grade math: 11.9 x 59 = 702.1! Conclusion: We must remain extremelly skeptical…
My best "tank" MPG? 61.3 for 503.8 miles at 26mph. Other "bests" are shown in my signature, below, as well as my lifetime numbers for City, Highway and Overall. At 7,081 on the odometer, yesterday, my lifetime fuel economy (from the MID) was at 56.8MPG. The total calculated fuel economy, for 15 tanks, is at 54.1MPG. My mileage has taken a "hit" lately, as I've been taking my new Prius to the body shop a bit too often. (Ref.: Again!! Second Prius to be Hit -- Back to the Same Repair Shop, I Guess and Again & Again!! Third Time to be Hit in Four Months -- Back to the Same Repair Shop . . Again!)
Very nice, you beat my best "tank" MPG by 0.2! The explanation may be your average speed was 26 mph vs 31 (mine). Just curious, how are you calculating your lifetime combined mileage? I'm not sure what the best way to do it is...
Nice! keep up the good stats, and hurry up with the first Gen III 700mile per tank. I still remember how jazzed I was about doing my 1st 700 mile tank. Immediatly I was encouraged to shoot for an 800 mile tank. whew! that tough! ... still workin' on it ... but it's closin' in .
hill, you are the MAN, and I will never reach your numbers. I just don't have the commute for it. My daily drive kills my mileage, and the only way I get really good numbers is when I am doing long drives to out-of-the-way places. I get a few of those trips each year, but only one of those, typically, will be long enough to give me a tank's worth of gas. If that trip is in the late spring or early fall, when A/C use is lower, then I may have a shot at a high tank. BUT, I also need to start the tank early in that trip, otherwise I just get two tanks with little increases! Think about this: My most recent fill showed a tank at 54.0MPGs at 483.0 miles (20mph). This tank covered 26 days, and the last 93 miles were in one day. That means the previous 390 miles happened across 25 days -- fewer than 16 miles per day. Now a good week of that was while the car was in the shop for repairs, but think of the great mileage it was getting at the hands of those folks. Can you imagine what it got during the test drives and moving it around the yard? Eck!
What? Your numbers are right there in the high end of what has been reported here and there (above average)... Your commute may not be the ideal but you're doing a great job!
Don't worry, you'll be getting better tanks along the way. I expect you'll pass me by soon enough! For calculation of lifetime combined mileage, I divide the total miles by the total gallons. When it comes to using the MID info to do this calculation, I simply determine the gallons used (according to the car's calculations) by taking the MID's displayed miles and dividing it by the MID's displayed miles per gallon: Miles/(miles/gallon) = gallons. I don't know how other folks do it, but I've been a bit worried that people simply take ten MPG readings, add them up and divide by 10. If each MPG reading was for the same number of miles, then there would be no error. If the MPG readings were all for tank fills, and each tank fill was pretty darn close to the same mileage each time, then the error would be fairly small.
I take my best single segment mileage and claim it as my mileage. It has no basis in reality or accuracy, but it feels good. Besides, always remember that you can hit Reset if your tank mileage looks too bad. Tom
