So I've been struggling with my overall efficiency in the winter. Averaging well into the 330's+ at roughly 20 degrees. Some say that's normal some say that's way to high. Then of course the "don't use the heater," "use heated seats only," "pre-condition the car before leaving."
I've tried the no heater thing. And it gets cold quick and even with my coat on it's just not pleasant. But I don't need it a thousand degrees either. So my thought process was I'll set the heat to auto 68. Should keep the heater usage low and I won't be miserable. Car efficiency really didn't change at all, still in the mid-300s. So I decided to tinker with heater and set everything manually, my gosh that improved my efficiency greatly, and I have it set warmer then I did before!
Manually set to 70, fan speed 1 (or 2 if it's in the single digits), vents+defrost and I've been averaging under 280wh/mi.
I've yet to see anyone say anything about moving off auto and manually setting the temp (or maybe I've just missed it) but for any new owners out there like me experiencing winter for the first time maybe this will help you!
