> I am a lead foot and get about 14 city and 18 highway. However, I’ve noticed during winter my mileage drops drastically which i found strange. I average maybe 12 city and 15 highway, at best. I do not idle my truck for any more than 30 seconds to 1 min before driving. I get my fuel at the same gas station year round 99% of the time. So i am not sure what the explanation is. Also, I just took a 6 hour road trip where I was in no hurry, set my cruise control at 60mph the whole way and got 20.3 mpg on the dash. Filled up just before hitting the highway then again when I arrived and divided the miles by the amount of fuel consumed and came up with 20.2 so I found that pretty impressive.

winter your mpg drop thats obvious.
