Read Something Interesting
We have all noticed the drop off in MPG during winter and wondered why. Well, we aren't alone.
If was reading through a EPA paper and the generally accepted reason is that cold weather air is denser than summer air. The vehicle has to push aside CFM of air but in winter that air is 10-15% denser and the truck has to do more work to bulldoze that heavier air.
There's your answer. Normally I don't trust the EPA, but checking against a psychrometric table confirms this.
