In the last 2 weeks since I picked up my 2004, I have filled it up, then put 2 full tanks through.
I put in 13.3 and 13.2 gallons, and averaged 22.1 then 21.6. This had a slight increase in highway miles from my typical driving (Mainly on the first tank) but on the same driving I got 14.5 - 15.5 in my Charger R/T. This is actually about the same I used to get in my 2001 PT Cruiser with 5 speed.


It was 296, then 285 miles per tank when the light came on with suburban driving and rush hour driving into work.
I think I will save about $50/month on gas, which I will put straight into a fund for tires.


Everything I read about the estimated MPG lead me to expect high teens in my driving, not over 20.
