Just wondering what you guys are getting un-loaded. I've been lucky to get 15. Is this normal or what? A couple times I've gotten 13.

 

I have 3.55's and get around 18-19 Dad has 4.10's and gets 15-16

 

i get 17-18 unloaded and when i am pulling my trailers i usally see 13-14 never below teens i too have the 3.55. whens the last time you changed a fuel filter????????

 

Sounds just like mine! I got 17 once with Smarty on fuel saver going 300 miles at 65mph....

 

Hey CODODGE... Do you have stock tires or you running mudders?

 

My auto gets 15-16 unloaded. I am not impressed with its mileage even with the ez. I have 3.55 gears with upgraded air filter and changed fuel filter 5k ago. I think the 5 speed gets a couple more mpgs.

 

I get around 20 hwy (70mph) and 15-17 in town. It's not too much different on fuel saver mode w/ Smarty. 3.55's and Michelin LTX M/S

 

i got 14-16 (depending on how it was driven) with my 01 6 speed 4.10 gears and 305 bfg at's when it was stock

 

18-19 on the highway if I don't go over 75. 11-12 pulling the trailer whether I go 60 or 70. Stock size tire, 3.55 gear.

 

I have 4:10s with 35in mud grapplers and and I see 16-17mpg driving it not so easy but most of it is highway.

 

3500 dually, 4x4, auto with 3.55s, I see 16mpg pretty consistantly(unloaded 2/3 highway, 1/3city). Doesn't seem to matter where I set the Juice it stays the same. I'm not sure the tc is locking up though.......

 

I get 16 to 17 regardless of conditions if kept under 2000rpm. 3.55 w/265s. I was hoping to get 20 when I converted from a Hemi @ 14mpg to a CTD , but haven't seen it yet.

 

i got 15.5 pulling a 16 foot light load all highway get about the same in town unloaded.

 

My best towing mileage was 16.5 @ 65-70 MPH. Unloaded varies alot, depending on how much playing I do. These mud tires kill mileage, before them, I averaged 20.5 with mixed city/highway and my best of 24 when I set the truck at 65 and drove non-stop 700+ miles on one one tank.

NOTE: Be sure to hand calculate, the overhead is way off when things are not stock. Mine claims better mileage when running the JUICE on 5 because it does not get an accurated read on how much fuel is being delivered.

NOTE 2: Be sure to adjust for your speedo imperfections/ bigger tires. Stock tires are 30.5" for my 99', which comes stock with 245/75/16's. If you are too lazy to measure your tires and divide the diameters to see a ratio of how much your odometer is off, on your next road trip, reset your tripometer right when you pass a roadside mileage marker and after 100 miles of roadside markers, see what the tripometer reads, if it read 94.4 miles for example, your speedo is 5.6% off and so when you hand calculate your mileage, you need to multiply miles by 1.056 to get the real amount of miles you traveled so you get an accurate mileage read. My half worn out buckshot mudders for example are 34" tall and make my speedo off by 11%. I double checked using the roadside markers cause I wasn't certain that the stock speedo had never been corrected, and low and behold, it ticked 88.7 miles when I had really driven 100 miles.

NOTE 3: You can also do this test with just a ten mile stretch, but you need to be more precise at starting the tripometer and looking at it right as you pass ten miles worth of markers. If you go ten based on roadside markers and 9.5 based on tripo, you're speedo/odometer are 5% off, but this is a little inaccurate as each tenth = 1% so you've got to be nearly perfect at start and stop mileage to get an accurate number.

Hope this helps, have fun, air up those tires, and keep your foot out of it, unless you wanna go FAST!!!

 

I notice a big change with the outside temperature. Here in Utah when its cold, I get 2 or 3 fewer miles per gallon. I probably average 18.5 overall.
