May I suggest that you join fuelly.com and keep track of your accurately measured MPG? I find it a helpful site. Then show us a picture of your 61 MPG segments or tanks at Best MPG segments - Picture Thread | Page 3 | PriusChat Great going and welcome aboard.
A similar segment at same temperature. I am running 40/38 psi, don't use ECO mode, and manually manipulate AC to stay relatively comfy. Thanks for the picture, OP.
I did not like fuelly until i got the phone app - now i don't have to remember the stuff until I get to a computer, and its no longer a hassle to add my fuel-ups.
Thanks! I wasn't aware you could put a shortcut on the phone. This makes it much easier now! FAQ: What is Fuelly Mobile for phones? | Fuelly in case anyone else(like me) didn't know
