temperature vs mpg

Global warming is good for gas mileage

My gas mileage dies a bitter death when it gets cold. i'm halfway to work before the coolant is warm. only 9 miles/15minutes from work

I had the same problem on my truck even with a full grill block. since covering about 1/2 the radiator itself with cardboard, it's to 175 in 2 miles, less on highway (50-60 highway), once warm, it wanders 175-190 with the t-stat. my thermometer is also in the bypass/heater hose so it's not quite as accurate as actually being in the housing but it's close.

Having a diesel the engine will never get warm in winter (-10 celcius and below), at least not when driving efficiently.

If i drive over 90km/h or racing style it sure gets hot but then there is no real fuel efficiency benefit either

A block heater helps a lot, especially for the diesel that runs really rough and smelly when it's cold.
