A bad O2 sensor is my first guess.
Improper inflated tires. --check the door jamb for proper pressure.
Or inflate to max pressure on the tire. It will +2 mpg.
Lots of stop & go. --Try to keep it rolling.
Short trips on a cold engine. Bad.
These can kill your mileage.
A well maintained engine is important.
Run the on board diagnostic test.
Click the ignition on, off 3 times leaving it on after the 3rd.
This give a very good rundown of trouble codes.
Anything broken may still be covered by warranty.
I have found the trip computer to be a great teacher. If you have one.
So far the trip computer has taught me to keep the RPM's low. Period!
Approx 2K RPM will allow all 4 gears to shift.
Also, Overdrive is your friend.
If you can get the car into 4th gear, your mileage jumps up.
It kicks in at 38+ mph, But you can slow it down to 32mph before it kicks out.
This works pretty good around town.
It can kicked you up to 17-18 mpg.
Also drive with a light foot. It increases mileage.
Good Luck,
Tom
