Okay so with gas being $2.67-$2.79
What is everyone else getting on gas mileage on a full tank?
Because I'm only getting 280-304 per tank of gas

Sounds about right to me. Maybe 310-320 (around 19-21 mpg) if i baby it all the way . Got new ngk spark, new front o2s, clean tb , new fuel injector orings and new fuel pipe ..

My LHs however gets 22-25 (so about 300+ on the low side) same driving.

Must be the M being a special i guess....

We've seemed to average about 20-22mpg on our '02 300M base.

I average about 20 mpg, it's about 80% City / 20% Highway though.

411 miles to Harrisburg took 14.717 gals=27.9 MPG best I've seen on this car.

Bob did some of his magic at Carlisle I forgot to check return MPG when I got home, will check in afternoon but I did finger the EVIC in CT and saw 29. Finally getting MPG approaching what my million mile 01 was doing.

Upper and lower 02 sensors (4) were replaced about 5 weeks ago, that also might of helped.

when got mine (in really bad shape) and had to get it home from 500km/312 miles away.It did 9l/100km (thats @30mpg).Thing is I drove it at 80km/h.Maybe the thingy that counts the mileage is not working right but I kept it at under 2000rpm when possible.It took me almost a day to get it home.Had to do that since it had other problems ...problems which made me make this account here :?

I think at 50mph (80kn/h)....30mpg is about standard .... Maybe a bit more like 31-32 when new o2 sensors,sparks etc...

*BUMP*
I recently drove back home to Northern Virginia from Durham, North Carolina; and I averaged about 32.5mpg at 70MPH (cruise set for the whole trip)... used just under 1/2 tank for the 220mi trip.
