Toyota Prius: Question about MPG

The car has a built-in mileage computer. According to that computer, I
averaged 51-52 MPG from last September through the end of May of this
year. Mileage dropped to about 48 in June and 46 in July, but it's now
back up to 51.

I live in the Phoenix area, and temperatures were 110+ most of June and
July. Now they're in the high 90s or low 100s.

My driving is a mixture of metropolitan-area freeway and suburban/rural.
I use cruise control wherever possible and try to keep it set at 65 on
the freeways.
 

The Prius in the US has a bladder inside the gas tank, so fillups are
not consistent because of bladder elasticity changing with temperatures.

Also keep in mind that a ten percent variance from 55 MPG (EPA average
MPG for the Prius) is 5.5 MPG, whereas a ten percent variance from 20
MPG is only 2 MPG. When comparing variances from the EPA rating use
percentages, not absolute numbers of miles per gallon.
 

How do you expect anyone to email directly to org?

I do not understand how your Prius can get such good of mileage. I'm in
the same hot environment in the So. Cal Central Valley and I'm only getting
38 mpg now with AC running almost always. Very odd, although the local
dealer has no explanation as to why a couple of Pri's in a company pool vary
so widely in their mpg's. Even though the drivers rotate between them, they
still produce the same mpg for the most part (one at 37 and the other at
46). Must be good ones and bad ones?

Best I did was 51 mpg in San Francisco, but that area didn't require AC.
Fwiw, my AC does work pretty darn well and cools down within two minutes or
so. Maybe the compressor drag accounts for some of the differences?

Running I-5 the way I do (85+) can get it down into the upper 20's to lower
30's. Also, our gas is pretty watered down during the summer months with
the "blend." Don't know if Arizona has accepted the watered-down ethanol
stuff yet?

I can tell a Prius isn't in your future. Buy something else which already
has a bad reputation that can't suffer from more negativity.

I don't understand why people wonder why they are getting low MPG when
they continually drive on the interstates at high speeds while running
the A/C. The Prius is very capable of achieving over 60 MPG once you
realize it's not a sports car.

I suspect there are some Prius that have undiagnosed problems that drop fuel
economy into the 30s. We used to see a lot more of those reports in the
Yahoo Prius forum, but they have become less common for some reason.

Assuming your tire pressures are okay (the stock pressures will cost you
about 5 mpg and wear the tires rapidly in the first generation - not sure
about the current version), there are a couple things that have been known
to cause such poor mileage. The first one is easy enough: some shops
overtension the parking brake cable and the parking brakes drag. If you use
the parking brakes regularly that goes away in a week or two, but applying
the parking brake hard and releasing it about ten times apparently does the
same trick. The other one was only reported once: the fuel injectors tested
bad and were replaced under warranty. Problem solved.

I don't know why you're getting such low mileage. As I said, I tend to
keep at 65 on the freeway; most of the rural driving is at 45 to 50, and
in the city it's 25-35. The lowest I've ever had was 42 MPG, and that
was on my first tank.

I make heavy use of the cruise control whenever I can, and the rest of
the time, I keep a light foot on the go-pedal, and try pulse-and-glide
whenever I'm able if I can't use the cruise control.

I know people who routinely get the high 50s or even low 60s; I don't
know how they do it.
 

We get MTBE in the Winter and ethanol in the Summer.

What tires did you get? I want to avoid them when I have to change
tires.
