Here's a bit of a question...I have an 05 Prius from Nov 05 and just
moved. When I lived in my previous location, I was getting between
48-52mpg regularly...like clockwork.
Since I moved, it's dropped to 39-42...quite a drop. I am taking
similar roads as before (mostly highway) and my mileage will not
improve...I tried different gas stations, new oil change (I use Mobil
1), checked the tire pressure. Nothing...
I'm getting a bit frustrated, because nothing has changed except where
I live and that can't be the only factor for the mileage change...
I have 22,500 miles on the car, and was wondering if any others had
similar experiences or solution suggestions?

Temperature different where you are now than where you were then? Winter
gas (with 10% ethanol) vs. summer gas?

Temperature...no, not colder by much, maybe 3-5 degrees max. When I got
the car it was winter time and was getting 50mpg, so that's what's
concerning me. I wish there was a reboot of the car, maybe it would
reset anything that has adjusted itself.

It may seem a long shot, but there was at least one report of a similar
economy drop after the car was serviced. It seems the parking brake was set
too tight; operating the parking brake forcefully a dozen times or so
cleared up the problem.
Otherwise, is it possible the drop is from terrain near your new home,
sucking down gas during the first mile or so of cold driving?

Are your trips shorter now than at the old location ? Efficiency is poor
for the first 10-15 minutes so if your trips are < 30 mins then this
tends to drag down the average MPG quite considerably.
