How much gas does it use??? Say for about 10 - 15 minutes.

Cars idle at a low RPM when in park, so it really doesn't use much gas at all. 10-15 minutes worth of warm-up time might use a few cents worth of gas, more or less depending on the vehicle, engine, and temperature outside.

A modern engine doesn't use as much gas, as opposed to the carbureted 70's and 80's cars. Most of them have fuel injection so a small amount of gasoline is required for the fuel pump to push into the cylinders. Starting a car takes a little bit more than actually running it at freeway speeds, but it's such a small difference that it really doesn't matter.
Unless you live in Fairbanks, Alaska, the less your car idles, the better mileage you will get. However, since the transmission/transaxle needs to warm up a bit (the lubricant is pretty thick at below zero temps) and the tires are a bit out of round, the mileage will also be temporarily lower if you just get in, start it up, and drive away.
This is an age-old question that has never really been satisfactorily answered, to my knowledge. For the most part, 2-3 minutes is more than sufficient in cold temperatures; just make sure in extremely cold temps (like under freezing) you start the car in neutral to allow the transmission to warm up. Manual transmissions don't have that problem as much but should still warm up a bit.

Suprizingly enough, you dont waste too much gas at all! The first inital turn your key in the engine is what takes the most gas. So, if you are going to warm your car off leave it running instead of shutting it off after 5-10 mins and restarting it....that takes much more gas than to actually let it run! Anytime it is cold outside it is best on your car if you warm it up awhile before you drive it anyway, PLUS, you'll be warm too!

Depends on the car, If it is something big like a hummer, a lot, they are petrol Guzzlers, if you have an average v6 or somehting similar prob half a litre to a litre. if you have a small car with not much go in it, you could let it warm up all winter if you wanted it to. =D

"...unless it's below freezing, cars don't need to be warmed up at all....driving them gently is the best warm up there is....if it's 25 degrees out, you might want to let it warm up for 30 seconds....if it's 10 degrees out, warm it up for a minute....if it's -10 degrees out, move somewhere warmer...."
