Taking my first road trip in the beast from CO>SoCal>NorCal>CO and am hoping I get over 30mpg. Currently holding steady at 25mpg with 80% highway.

I'll report back what the car says (too lazy to do the math myself) as I go along each leg of the trip.

I forgot to to add that I have > 5k miles on the car
