Toyota Prius: Frustrated prius believer question

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.

I think it is due to the locale and not the car.

Where I live, I get around 42 mpg.

If I venture to the San Francisco area it jumps to around 50 or better.

I go back home and it drops.

It's been consistant in its behavior so I no longer doubt the car, but the
area has more impact.

Alignment?

I would guess a combination of temperature and local driving conditions.
My economy dropped by 10 mpg between September and December. The only
difference is average temperatures in the 30s instead of 70s. Also, the
first five minutes or so of driving can have a huge impact if you do
mostly fairly short trips. If you sit at lights a lot or go uphill in the
first few minutes, your mileage will really suck and it takes a lot of
driving under more favorable conditions to make it up.

Should I be letting my car warm up on colder days to minimize any gas
sucking from driving?
