Heating, Cooling, and Fuel Economy
Hi, It's well into winter here in Minnesota and I have a very very simple question about how heating and cooling affects the fuel economy of a car.
Does it require gas to run the heat? (temperature dial is set all the way to red)
Does it require gas to not run the heat? (temperature dial is set all the way to blue)
Also, how long should I run my engine before driving in cold weather?
