So what's the worst mileage you've gotten?

The worst mileage was 42 mpg on one tank. That was due to the bladder tank I am sure as it was preceded by a 62 mpg tank and followed by a 53 mpg tank...all with the same driving.

I am not sure it is possible to see a true drop or increase with just a couple of tanks as the bladder keeps one guessing if the tank is really full.

 

i can't seem to get a tank lower than 34mpg.

 

33 MPG at 70 MPH with a 30 - 40 MPH head wind... in most cases I get 44 - 46 at 70 MPH... but at 60 - 63 MPH I get 50+ MPG

 

54 during the winter. My parents bought one at the same time and never get above 52...I am not sure why the differnece. Mine is basic, theirs is Touring.

 

I live in Chicago, I put 125-200 miles per day on mine. Stop and go city and highway. I dont waste time getting places my buisness relys on me getting to my customers as soon as i can. When the weather is above. 70 i will almost always get 48-52 when its 20 degrees out i get 40-42 when its zero and below i get 38 ish. And like i said, im not shy about steppin on the gas.

 

Oh my that's great mileage!!! We have the same year/model and I CAN NOT get above 45 a tank! ??? (could a slight alignment issue be that big of a factor. I'm wondering if I have one)

Worst tank for me was 42. Once for a few miles I was in the high 30's and panicked, but it moved back up quick.

good thread. my lowest is 42. that's driving like an idiot. i came from a 06 STS V8, i punched that car whenever i had the chance. guess it carried over when i first got our prius.

LOFTISHB - the touring has bigger rims, stickier tires, so the mpg is not going to be as good as the standard. i wish i had a touring - i would gladly give a few mpg's for the performance/handling. cheers to your parents.

CHRISSPALDING- have patience with your prius. once you get used to driving your prius in the most FE way,you will also get the great mileage. follow many of the great tips like what EFUSCO and more posted. learn the concepts of pulse, glide and warp stealth and you will love it. getting great mileage requires "mature" driving habits. it will come, have patience. good luck.

 

Worst tank -- was my first tank: 38 mpg in Jan.

5 months later, in the weather & having figured out the hi-mpg techniques -- I'm doing 65 mpg

 

My worst tank was also my first one 40.9 mpg. I have seen the avg go down as low as 38 when I drove up to Sierra At Tahoe (~6800 ft) but it climbed back to 48 on the downhill return trip.

 

Fourth tank early spring '07 @49.2 since then all above 50 with the last 7 all >60MPG.

 

42 mpg seems to be a popular low number. That has been my worst gas mileage so far. My best, not for a tank of gas but for a short trip was 77 mpg. I couldn't believe it. It was mostly downhill, in town, with moderate traffic rarely going more than 35 mpg. Still what a hoot to actually see 77 mpg.

 

My typical drive: less than two miles, stop and go (mostly stop) all the way, and hilly to boot. Below-freezing weather has given me a couple of 37 MPG tanks.

 

I average about 48 mpg. I drive from Bakersfield California to Valencia Ca. (Daily Commute 85 miles one-way) I drive Interstate 5 over the Grapevine. I start out at 400 ft. elevation and the top of the Grapevine is 4144 ft. Valencia I believe is at about 500 or so ft. elevation.

The only time I have seen a big difference in my MPG is when I switched my Integrity's for Goodyear Assurance Comfort Treads... My first tank was 35 mpg. I almost panicked ... but after a few tanks I am now back up to my 48 mpg again... I do get blown all over the road and I bought my vehicle used... so perhaps I should have my alignment checked. But the horror stories I have read here have me scared to death...

 

The bladder won't have an effect on overall average milage. Did you try to use hand calculations for the tanks you mentioned?


My worst tank was during a terrible storm and on my usual 76mile commute. There was debrise flying across the road and rain so hard that you couldn't see more than a few truck lengths ahead of you. I managed around 35-37mpg (I do not remember exactly).

 

my worst to date has been 43 mpg, 42.7 but rounded up

 

What is the "bladder tank".

I was getting 48 MPG, but the current tank is getting 42 via the consumption screen.

Also I see a 3 to 5 MPG worse MPG in my calculated MPG compared to the consumption screen. Anyone know or gets the same indication.

 

We are only on our second tank of gas. First tank we averaged 42.6 - not as good as we expected. I'd read here about how the first tank of gas can be the worst - but we live in the mountains at about 3000 ft elevation, so it's up the hill.. down the hill.. up the hill.. down the hill.. so we weren't sure what to expect. But even so, our second tank is ending it's average at 46.8! We fill up again first thing tomorrow.
