Use more gas in winter?

Just a quick question.

do you use more gas when its cold outside than when its warmer?

any comments would be helpful,

Cooler air is more dense and therefore requires more fuel to achieve a stoichiometric(14.7 parts air to 1 part fuel) mixture in your combustion chamber.

Also it takes your engine to reach optimum(read: most efficient) operating temperature when its cold outside. Factors such as removing heat from the engine to warm the interior and the running of the A/C compressor to defrost your windows will also increase your fuel consumption.

Not to mention no traction in first gear, fuel wasted when you put your foot on the gas and car does nothing but spinning its front wheels.

everyone wastes a lot more gas warming up their cars before they drive (if you dont then its just bad for your engine)

also the gas companies have addatives in the fuel in winter (probably so its less likely to freeze) which reduce fuel economy.

Its not bad to drive your car when its cold. Its bad to rev the **** out of it when the engine is cold. Actually driving the car is better than letting it warm up at idle.

Hope I'm not high-jacking this thread but do you think I should let the temp. guage on the dash show normal temp. before going on the highway? Cause I live 5mins. from it and in the winter I bet it wont warm up by the time i get there unless I let it warm up.

i live like 3 mins away from the highway and my car was always at operating temp before getting there in the winter, this is with no more than 1 min ofof warm up.

i believe you should keep the revs 3000 rpms or lower until its at operating temp

Electric....and coolant. The electric fan blows air past the heater core, which is like a rad with hot coolant flowing through it.

k thanks, I guess I won't have to let it warm-up very much or anything. But just incase it isn't warm, do you know what speed in 5th is below 3000rpm? (thanks to my CX model I don't have a tach)
