Average my truck gets about 18 mpg. About 15-16 city, 20-21 highway. I didn't get it for gas mileage. I got it because it's a beast! I do regret not getting a 4WD beast....

 

I get 19 HWY and 17 CTY, which is a big improvement over my 04 4.7L that on a good day got 16 HWY.

 

i got a couple more mpg by holding the trip reset in and turn the key one click then let off the trip reset and all the lights came on on the dash and the needles went all the way up and back down. and then it flashes something where the odometer reads but not 100% sure what it said.

 

I have a Super Chip and a K&N CAI. I get between 13.9 and 15 in town. I save a little by setting the Super Chip to the 878 octane setting. Thats 20 cents per gallon. But I didnt expect this truck to get good gas mileage.

 

On my last trip I got about 15mpg, but that was going 75-80 most of the time, plus we were heading into the wind.

 

if you have higher milage and you havent changed your EGR valve or spark plugs are due...change them- you'll see an increase of mpgs.

 

dont care about mpgs thats why i got the hemi all i want is some more hp.lol

 

I never check my MPG's anymore. I figure on an average tank though I get about 10 smiles per gallon. I get an extra smile per gallon by lining up next to f150's at the stop lights.
