Drop in gas mileage

[AK]

I moved from a relatively flat area (Houston) to Central Texas close to Austin.

My gas mileage has dropped from 20 mpg to around 16 mpg.

I would like to find out why. I have a 2009 Mazda CX-7,

The engine is running fine. I do live in a very hilly area.

Thanks.

Hills maybe but are you driving more city streets and less
expressway? That's a big change too.

I found that my tires were at 22 p.s.i .

I filled them to 32 p.s.i.

I anticipte an increase in my my miles per gallon.

I mostly drive in my little town and get around 18 MPG in a 2011 RAV4. I drove to work on the other side of the mountain and got 30 MPG. I typically get 27 MPG when I drive to work. The main difference was that I didn't use the AC. Having the temperature in the low 70's and no passengers and no stopping probably helps.

After airing my tires to 32 p.s.i., my mileage went up to 20.2 mpg from 16 mpg.
