I've been averaging about 19.5 mpg with my SXT AWD. I have done the calculations based on fill-up and it is very close to the trip computer's onboard reading. It read 19.7 when I calculated 19.5.
By resetting the mpg reading on different trips (same route - 40 miles to work), I have seen that at the same speeds (around 60 mph), I can get my Journey up to 23 mpg if I don't use cruise. Since it's a long fairly stright trip, I usually use cruise control for 90% of my ride, but I may try a week without cruise to see if it makes a big difference. My thought is that since my trip is very hilly, so the cruise control may not be regulating rpms as well as it should. Over the 40 mile ride, I go as high as 1650' and as low as 550'.
Has anybody else seen any difference with and without cruise control set?
