On my trip to work I have several flat stretches so I held the car at 45 mph to get a level mpg reading and then turn on the heat and my mpg would drop by 2 (4% loss).
Even though I did this test 20 times (16 of 20 lost 2 mpg, 4 of 20 lost 1 mpg) I know it's far from being a scientific set of A-B-A tests.
Frostbite is not sexy so I'll still be using the heater, I was just wondering if anyone else noticed lost fuel economy due to turning on their heater.

Seems like some did not read the original post, or does winter strike the instant he turns on the heater
