    My new to me 2008 is getting around 45 in the city and this is with me constantly watching the screen, coasting, gliding, using cruise control etc. I am just curious if anyone has experimented with going an entire tank where you just drive and not worry about hard accelerations, coasting, etc and how much of a difference that made in MPG

    If I drive my 2007 without a care in the world then I'm around 44-46 in the nice weather. If I pay more attention, using the same exact travel routes, currently 53+.

    Here's a picture I took this morning when I stopped to fill up.

    Yup. It's the difference between 55-60mpg vs. 47-50mpg when I had the Gen 2 back in the day.

    on my 08, i could go from 45 all the way to the low 60's under the right circumstances. (on the screen, not actual at the pump)

    I don’t think I could do that. It’s not JUST for fuel economy; it tends to bleed into tailgating, lane jumping, speeding and flipping off “slow pokes”, rolling stops, and so on. Oh, and leaving it running with the AC while you run into 7-11, idling in drive-thru’s. Ugh…

    I haven't found too much difference between "driving like a saint" and a little less saint-like between identical trips on different days.

    Biggest variance I've seen to date has to do with how fast you cruise.

    Next bigger one is the outside temperature.
