Ive been averaging 22.3 indicated (23.3 actual) w/ normal driving 15% city/85 % highway.
I decided to try coasting down the hills on the interstate and in town where possible. indicated MPG went up to 25.5 MPG and actual was 27.0 MPG..
It is a pain to do this but it was pretty interesting to watch the MPG go up when coasting.

Just thought i would share....

 

was doing that too for the first couple of tanks, drive almost only city, had it about 20-21.
but doing the opposite passed few days.. seeing how low i can get it
seems to have bottomed out at 18-18.3

 

Short shifting(2000 rpm max), super soft throttle application, keeping the rpm as low as possible and running in as high a gear as possible are the real keys to best fuel economy.

 

There was an other thread like this today on here already

 

Ha beat that!

 

Damm bottom out at 18?!?!? If I slightly get on the car my avg MPG is about 14 and that's all city and babying it 85% of the time. If I'm always on it I'm down at 10.5

 

I get 17/18 all around in my 500

 

The smog must be combustible.

 

I push it by hand a couple miles every gallon.

 

You should do the Fred Flintstone mod. Easier on the hands.
