Tank Miles: 281.9
Total Miles: 4166
Tank MPG: 34.2
Lifetime MPG: 44.08
Avg Temp: 20s
Price of Tank: $15
Price per Gal: $1.92

Some of the variation is due to the cold weather. At 4000 miles I had the first oil change done. The Toyota dealer seems to have put the right amount of oil in (just a hair over the full mark at operating temperature) and the tire pressure I requested (40 psi front, 38 rear).

If memory serves:

1 500 miles at 42.7 MPG (75+ mph for long trip)
2 640 miles at 56.6 MPG (normal commuting)
3 440 miles at 51.7 MPG (70+ for 1/2, normal commmute for the other half)

I have a brand new Prius - this is my first posting. On a trip to Pittsburgh, I put in some gas at 291 miles and got 45 mpg. Just filled up yesterday again and it took 8.03 gallons odometer 694 miles so that works out to just about 50 mpg even. You folks who are getting milage in the 30's must be pushing the car too hard! http://priuschat.com/forums/images/smiles/...nsfiring_v1.gif
Guns firing It can't all be because of the cold temperatures. I like the instantaneous milage display - they ought to require such a display in all vehicles - hybrid and conventional - then these guys driving the gas-guzzeling SUVs and luxury cars could see how much they're wasting in real-time.

Tank number 4 590 miles at 53.7 MPG

A casual trip to Cache Creek Casino from Sacramento registered 58.3 MPH on the MFD/ about 3000 miles on the car, speed extremely conservative 55MMPH freeway and speedlimits on CA State roads. I am inclined to believe that the MFD computer calculated mileage is extremely accurate as compared to a calculated figure mainly because it is impossible to determine when Full is Full, so 8.03 Gal for 694 miles turns out to be 86.43 MPG. One cannot stop filling at the first click and thus far I have not gone so far as to overflow. So......that leaves the computer. Also if one wants to go to the trouble, one can use moderate power up a hill, then remove foot from accelerator and step back on lightly, at that point you will either get total electric or freewheeling, does not matter. Then after entering downslope let her ride. If you want faster go to freewheel, if you want slower go to B. This system works very well on small rolling hills. I noticed that every small regeneration will allow a freewheel or electric only mode. A 50% workcycle may even be possible. Will also not work at all without a full warm-up. (20 min) Andy

Well, I was never a lead-foot by any stretch of the imagination. Trust me on this:

At -40, snow routing so stuck in creeping city traffic, Max Heat and still shivering, around 9 to 10 litres per 100km, or 31 down to 28 MPG Cdn.

At -40 on the Trans Canada at the posted 100km/h and minimal wind, around 7 litres per 100km or 40 MPG Cdn.

At 0 C, more "normal" city speeds of 40 to 60 km/h, around 4.6 litres per 100 km or 61 MPG Cdn. At 0 C on the Trans Canada at the posted limit and minimal winds, around 4.4 litres per 100 km or 64 MPG. That's with the Dunlop Graspic DS-2 snow tires on too.

So temps do make a huge difference. You just don't notice it as much in a vehicle that is already getting crappy fuel economy, like an Expedition.

Due to the extreme weather here in Northern California I have only been averaging about 47MPG. We have actually had rain! and the temps have been in the frigid 60's, that"s Fahrenheit. No matter how I drive I get good MPG, I'm totally disappointed! Somebody said when it finally warms up my Prius should get 387MPG. At least that's what he got coasting down Mt Everest!

Jayman, you get under 5 at 0°C?? Do you have a long commute? I got 5-6L/100km during the winter.

[Wolfman]

My last fillup for the month was done on the way home from work last night. 5 tanks of gas this month. Looking at my spreadsheet, I can watch how the temps have risen slightly over the month. First tank was 51 mpg by the computer, with the last one at 52.6.

Anyway, my averages are:

Tank Miles: 2513.0
Total Miles: ~43000
Tank MPG: 52mpg according to the computer (averaged), and 48.9 by the calculator (averaged)
Lifetime MPG: 50.8 by the computer 47.5 mpg calculated
Avg Temp: upper 20's to low 80's

Well, my Prius isn't starting at that temp. I have heated underground parking at my condo, and where I park at work is also heated underground parking.

My commute is usually 10km one way at fairly consistent speeds of 50-70 km/h. If I time the lights just right, I can feather it and coast part of the time.

My absolute worst fuel economy was near -40 just after the blizzards here when the Snow Routing was in effect. Traffic was a giant PITA mess, the commute time was 2X, and most of that time was with the foot on the brake pedal.

Couple that with Max Heat and rear defrost, and 9 l per 100km. Of course, that's still *way* better than most of the cars and especially SUV's around me.

Oh, my coworker with the new VW Golf PD diesel appears to have finally solved most of his winter starting and running problems. He's had it towed three times now with a gelled up fuel system and even a plugged filter. I helped him carefully investigate what was going on.

It turns out he was getting diesel at a small corner station. Well h*** that fuel could have been sitting in the tank for years. I pointed him to a large PetroCanada truck stop on the Perimeter that does very high volume.

Once he got over some irrational fear of parking next to a Kenworth, he has religiously purchased all his fuel at that truck stop. All his problems have gone away.

Still, his Golf gets around 5-10% lower fuel economy than my Prius. Although his Golf is more fun to drive, my Prius also doesn't stink like a Kenworth either.
