I recently bought a 08 QC Hemi 2WD and drove it from the west coast to the east coast. I averaged 19-20 mpg doing 80-85. In the city I get 13-15 depending how much I play with it.

 

Getting about 15.3 to 15.5 MPG on 60/40 hwy/city split. Did a run from Tulsa, Ok to The Woodlands, TX (just north of Houston) on a single 26 gal tank with only vapors left in the tank. Trip was started around 11pm in August so there was little traffic and i could keep the engine at a steady rpm setting. No stops where made.

 

07 Ram 1500 QC, 4.7 FFL

Im getting 16 in the city, 20 hwy somehow...K&N cold air + Royal Purple saved me 2+ MPG

 

New update:

Our 2008 QC 1500 with 4.7 is now up to 16.3 average over it's 3,000 mile life. It seems the price of gas has finally taught my wife to stay out of the throttle, and it has let the overall average creep up a little bit. And maybe the engine is loosening up just a bit with a few more miles under it's tires. Also, just changed over to Pennzoil Platinum full synthetic. We'll see if that helps any.

 

[sm=boohoo.gif]HELP!!!! 08 2500 5.7 hemi 4x4 with QC and 8 foot box. 11.3 in the city. Now I realize it aint no dang prius, but c'mon...... I'd feel a whole bunch better about it costing $125 to fill up if it at least had ballzzz. At least it looks purdy. Someone tell me the best bang for the buck upgrade?? Mebethinking a programer.....but which one?

 

I'm listening...??? ...last week ran10mpg ...felt good hitting 12.8 this week...that's just sick.

 

will i see a mileage difference with a tire swap? i have 275/55/20's now. will going to a 245/70/17 do anything? i have 3.92's

 

03' sclb hemi 4x4 w/ new plugs and bed cover-19-20mpg at 62mph on hwy

 

just checked my mileage today, and I figured out its only 11mpg city driving.

 

I dunno if I already posted in this thread but I get 16 city 23 hwy...a lot worse or a little better depending on my mood.
