After 1000 miles since my 4.56 gear, and 35x13.50 tire install, I'm getting a consistent 14-15mpg on the highway. Which is down from my 17-18 when I was running my 3.55 gears with 265/70/17 tires. Oh well, at least I shouldn't get stuck as much.

 

I got a new gas gauge that says it all....

Just got Back from Wenatchee...about 310 miles each way with two mountain passes. 2004 2500 4X4 and a stock Hemi. Got 18.8 going over....no 4x4...and 17.5 on the way back with 45 miles of it being in 4x4 and moving at 25-45 mph.

 

I have an '03 5.7 hemi Ram 4 X 2 with a K & N. I average about 13.6 combo. On a recent trip, I checked my mpg vs. mph using my trip computer.
60 mph = 20.9 mpg
65 mph = 17.8 mpg
70 mph = 16.9 mpg
75 mph = 16.3 mpg

 

2003 4.7 QC. I got 19.1 cruising at 80 on a recent roadtrip I just got the truck under 3 weeks ago. It has CAI and Magnaflow duals.

 

Hello Rammers, since I've had my leg in a cast for almostsix weeksnow, I just been going to the doctors, gettin' coffee different places, maybe to the stores to ride those electric Wal-Mart typecarts(a person could get too use to those carts)....So, since my work trailers been un-hooked, I tookthe truckto the local detail shop; put some good fuel in her; babied it around town, checked the mileage, almost 15.5 !!She's got 112M on her, I'm thinking that's pretty good.....

 

When you buy a truck get a diesel. Once you do you will never go back to a gasser I average 19.5 just normal driving back and forth to work never over 55mph. If I get to gunning it and racing around on the interstate 85 and 90 mph it'll suck it down really fast to about 17.5 but I can set the cruise on 75mpg and get 18. I have a hard time believing some of these 18-20 mpg claims from Hemis. The 14 to 16 sounds more like it. And the fellow diesel driver with 4:10 gears averaging above 20mpg? Ha! Not gonna happen[sm=forgetit.gif]

 

I'm getting about 14.5 on hills and city driving. I still need to do a road trip for a long distance to check highway miles. Hopefully with the MDS it will help.

 

03 QC hemi im getting 10.4 with 31's lifted front to level it out dual exhaust. what can i do to get better mpg?

 

Today we took our 04 hemi quad cab out for a little spin. we went about 70 miles in the country. usually I don't get over 13.4 but since I played around with myCTM Fuse asI was instructed to do in this forum I got 15.4 today. No interstate driving, just two lane roads with some stop signs. Never went over 60 mph.
