I have an 05 Ram 4.7L with Lone Star package running 20's and I get between 15-20 mpg

 

2005, 5.7L, 30,000 miles, toneau, magnaflow duals, 16.1 m.p.g. for last 6 months

 

05 1500 Quad Cab, 4WD, HEMI-POWERED!!! I've been averaging 16.6 on the highway.

 

04 1500 crew cab with 4.7 and a Tornado! 17.6 MPG. Up almost 2 MPG by adding the Tornado. Plus a lot more low end throttle response immediately obvious after installing the Tornado.

Also, just a little information that may be helpful. Using current gas prices and my current mileage, I calculated out the cost per mile from the MPG and what I paid at the pump. It is actually more economical for me to buy the EXPENSIVE higher-octane Supreme gas than the regular. It hurts when I fork out the cash at the gas station, but the numbers don't lie. It's about a 1 to 1.5 cent per mile improvement for me. And when every dollar counts, every little bit helps.

Of course actual mileage may vary. Not applicable in all vehicles. Not valid in Alaska and Hawaii.... blah blah blah.

ALSO!!! Can anyone recommend a Cold Air Intake that'll fit my 4.7 that isn't $300?????

FYI

 

for you 4.7 liter people out there intakes help alot. I put an A.F.E intake on my truck and it gives it about 1-1.5 mpg better economy. 16.7city 21+highway in my 03 qaud cab 4X4 off road.Just ordered my TB spacer and next is Gibson super exhaust.~~~anyone know where i can get good headers for under $300?~~~E-Bay has an AFE intake up now at 75 bucks i picked mine up there for $120 regularly almost $300

 

just did a 2k trip and on the way back to NC from MO it did 18.8 MPG on 91 fuel. Ran mid grade on the way out and it went from 15 to 16. Time to mod this bitch~

05 quadcab HEMI

 

04 hemi, QC, 17s, 3.73 K&N drop in

14.5 avg

Have seen as much as 21 mpg on a 350 mile trip at 70mph. That was reseting the mpg at the pump till I pulled in the drive. I have checked the computer reading to the manual reading several times and it has always been within .1 of the actual milage.

8mpg pulling 24' camper at 65mph


Does anyone have 17 inch wheels with 3.90 or steeper gears? how did that effect you milage?

 

only had it one day. but i have a 2005 1500 2wd quad cab hemi with 34,000 miles on it and it is getting about 16.8 miles per gallon.
