5th fill up: Miles to drive reads 551. Total MPG reads: 50.1 Total Computed MPG is 47.4. Last tank computed MPG is 47.25 Gas price went UP a couple of cents in the past 2 weeks. So this is consistent with the car "thinking" that it is getting about 3 MPG more than it is. This has got to be some sort of calibration error someplace. I drive a lot of hills and freeway miles. So ~47mpg is OK by me. Read more: Most recent tank | Page 16 | PriusChat Follow us: @PriusChat on Twitter | PriusChat on Facebook

I think mileage is also dependent on the level of charge in the battery. Whether it's depleted or topped-up when you start, it would influence the mileage.
6th fill up:I got the alert and the blinking. Miles to drive was 15 when I filled up. I put in 9.600 Gal. Miles to drive reads 541. Total MPG reads: 50.0 Total Computed MPG is 47.3. Last tank computed MPG is 46.9 So this is consistent with the car "thinking" that it is getting about 3 MPG more than it is. Gas is 2.669 - 41 cents higher in 17 days I haven't been driving so much the past few weeks [For 1 and 1/2 weeks I didn't drive at all], and when I did I wasn't trying to drive in an eco friendly fashion. I was "driving" like heck most of the time [that is accelerating quickly and sometimes had to actually use my brakes]. I also needed to use the heater a bit while stuck in traffic.

My ScangaugeII Flv Xgauge which read directly from the Prius' internal fuel tank sensor tops out at 11.4 gallons and bottoms out at .7 gallons. The Prius internal fuel tank sensor readings will vary depending on whether my Prius is going uphill ( higher than normal) downhill (lower than normal) or is on level ground (normal reading). My 2010 Prius low fuel warning alarm rings once when the Scangauge Xgauge FLV reads 1.7 gallons on level ground - but there is a tad more fuel in reality. The 2 gallon of fuel left estimate after the low fuel warning alarm and blinking bar is about right ( I use that tidbit to get 800 miles on one tank of gas) Because its pretty cold now, my Prius' overall MPG is lower than it would be in the summer time. To avoid getting all stressed out from driving - I allot more time to travel. The price of regular E10 gasoline is about $2.20 in the DC Metro Area which is affordable so that makes my wallet happy. Learning to hypermile my Prius - has helped increased my overall MPG almost 20%. Hypermiling isn't always possible but when it is - it can help boost the Prius fuel efficiency.

7th fill up: Total Computed MPG is 46.3. Last tank computed MPG is 47.1 Put in 6.872 Gal So this is consistent with the car "thinking" that it is getting about 3 MPG more than it is. Gas is 2.749 (Feb 22) [Posting about a week late] 8th fill up: I got the alert and the blinking. Miles to drive was 7 when I filled up. I put in 9.678 Gal. Miles to drive reads 531. Total MPG reads: 49.9 Total Computed MPG is 47.3. Last tank computed MPG is 47.8 So this is consistent with the car "thinking" that it is getting about 3 MPG more than it is. Gas is 2.259 - A big jump! I turned "eco" mode back on. I seem get about 1 MPG more with it on. I could probably go to 600 mi if I go "past" zero (on the "reserve") but it would make me really really uncomfortable.

Good on you for calculating and tracking mileage. But as far as seeking to extend distance between fill ups: pointless, and risky. I'd fill up sooner, say any time you're nearing 1/4 tank remaining.

Here's mine from Northern Cali. These results are from 17 inch Persona wheels with a pair of toyo proxes and a pair of cheap non lrr valera tires. and the temperature keeps climbing.
9th fill up: (10Mar2015) Miles to drive [after fill up] reads 523. Total MPG reads: 49.7 Total Computed MPG is 47.05. Last tank computed MPG is 45.5 So this is consistent with the car "thinking" that it is getting about 3 MPG more than it is. Gas is 3.19/Gal MPG is a bit lower due to heater use and more aggressive driving at times. 10th fill up: (today): Last Tank MPG: 48.2 Lifetime MPG 47.2, What the car thinks: 49.7.

Wesayso. How are the ep -20 tires treating you? Did you purchase two more or are you still only running two. Hal
Not sure what you mean with the 2 tire comment. I replaced the original ep-20 tires a few months back at 41K. They were shot. Replaced with Michelin Energy Saver A/S.

My first tank: 409 miles 9.29 gallons 44.02 calculated mpg Most of my rides were higher than that, but the car did have 10 miles on it when I got it - though that couldn't have swung it much. Curious to see how it changes over time. My best ride (not counting 5 mile little rides) has been 28 miles @ 55.6 according to the computer.
