Hey Canuck - there are very few places on Earth that are "routinely" -40F/-40C - and it's not Canada or Minnesota -

Uhh -40C is like arctic tundra. -40F is still pretty damn cold, but not anywhere near as cold as -40C

^ -40C = -40F. and it occurs frequently in edmonton (and many other locales) in the winter. google "unit conversion" FYI.

it's not a linear conversion. but at -40, they are equivalent. i won't try and explain the reasoning, it's science. 0C = 32F, but -40C = -40F. check out a unit conversion tool...

Weird! I never knew that....Also, once you hit -40, anything colder, the Fahrenheit temperature is then lower than the Celcius...interesting to know.

It's because 1* F (a unit not the temp) does not equal 1* C.

It's about 2 units F for every unit C....give or take.

^ for everyone's info, here's the conversion formula:

F = 32 + (degrees C) x 9/5.

for example, at -40C:

F= 32 + (-40) x 9/5 = -40F

I get pretty bad gas mileage I average about 16 miles per gallon..
Seems about right as I live in the city and rarely drive over 20 miles to a destination. Not only that but the all wheel drive sucks more juice!
Well worth it though..

When I bought the car used (04 sedan) it was getting 16-17mpg city-- I was in complete shock given gas prices. Drove around with this mpg for about 2 months and then decided to take matters into my own hands. Disconnected the battery cables and pressed the brake pedal 3 times for 5 seconds each. Let it sit overnite (12 hours), came back the next day (12 hours later) and depressed the brake pedal 3 times again for about 5 seconds each time (to discharge any potential charge remaining in the system's capacitators) and then reconnected the battery.

My driving habits resulted in a "retraining" of the ECU and an increase from 16mpg to 22-23mpg city and 27-30 highway. And this is extremely steep, in highly hilly terrain.

Understand that I drive my car like "on old man in a hat"-- don't speed around corners, gentle braking, very, very limited spirited driving, etc. The ECU programs itself to an extent (much like artificial intelligence) based on your pace and feeds your engine, over time, in a way that reflects your style. The previous owner like speed and power: I don't mind taking my time-- thus the difference in mpg.

Had the car now for nearly 3 years.
