Let's face it, these trucks just suck with fuel. For winter, I'm averaging 8.5 city, and 12 highway. In the summer, I get about 10.5 city, and 14 highway. The winter kills my mpg because 4wd is frequently engaged, and I often leave it running to keep the cab warm and the windshield defrosted.

 

With frequent 4x4 usage, I get about 9-9.5 in the winter, before the Flashpaq. Now on economy tune (and some report better MPGs on the performance tune with 93 fuel than economy with 87), including a 80mph 60 mile trip to my second job and back, frequent 4x4 engagements in town before and after that trip, I got just over 10. 1/3 the tank was stock tune, another 1/3 with Flashpaq economy tune, and I filled up with 1/3 left in the tank. Will be interesting to see what I get with the tune on all the time.

EDIT: Yes, I know, SCT would have been a better tuner, but $600 for #1 or about $350 for #2... sorry, on a budget. Wife barely let me get away with this, she would have killed me after the SCT. Will sell the Flashpaq and switch to the SCT if I add a lot more upgrades, but for the forseeable future, the Superchips is excellent.

 

98 4x4 1500 with 5.2-----Got a average of 15.8. I keep the rpm,s down and leave it in OD unless towing.

 

I had a 01 1500 4x4 quad cab, 5.9l with intake and exhaust i was getting 8-10.

 

95 3/4 ton 5.9l 4x4 = 10.5mpg

 

3/4 ton 5.9L 4x4 getting 10.5mpg is pretty decent in my book. I got 11 on my best days, and I weigh less than you. What kind of upgrades did you do, Mr. Iowan?

Greetings from your neighbor in SD.

 

i get 15 around town and 18 highaway with mine, and i have a 4.10 gear ratio.

 

What kind of specs for yours, breeves? 5.2 I am assuming? Manual maybe?

 

Greetings From Iowa. So how's the snow up there, all of ours melted today. Went from 3" of ice and 4" of snow to bare grass in a day.

My ram is bone stock with 160k miles on'er. (Side note has a 150-250lb topper). I might have to crack the engine open in the next 100k miles tho. She's burning about 1 1/2qt of oil per tank of gas now.

I knew the gas mileage wasn't the best but I didn't care since I have a I4 wrangler getting 22.1mpg for that.

 

jason, look at the sig 5.9 HO Diesel.....
