Right guys, I'm crossing my fingers that this will be due to more frequent short trips during the holidays. Typically, my drive is ~48 miles round trip to work with 80% of that highway. Thus, I've been able to enjoy decent mileage.

I expected the drop to about 29 mpg with winter gas, no problem. What I wasn't expecting was the drop to 24 mpg. I really hope this evens out as I return to my normal driving habits.

As a note, all my numbers have been from calculated mileage. The car estimate is typically 1-1.3mpg higher than reality and the instantaneous mileage is a joke! Tire pressures kept at ~35/33 psi, adjusted for temp.
