I love the FE so far. Only have 650 miles but acheived 43.89 mpg on first full tank with manual calc. So far on this tank, at about same level. 5M helps tremendously. Shift @ 2k on flat surfaces and not over 60 on hwy. I baby it and it treats me well!
I like to camp in my vehicle vs in a tent where bears can get to me. I can lay down in the back with nearly the room my 4-Runner had but with a much more FE vehicle! 18 overall mpg vs about 44 mpg so far.
