Did a quick mileage check a couple days ago (only about 150mi.) driving for MPG, doing 16 MPG in town (street and highway) my truck is cold blooded, got to be towing the 5er to get it up to 190, never seen 200 even towing in 95* + in town

Rodram I will try driving like that, but it will be hard. First I have to get my hoopty working correctly now. I'm throwing over boost codes and I my fuel pressure gauge said cya later.....

MPG shouldn't be that low. For the freebies, the max cold air pressure is a good thing. Saw 10% increase just doing that. I have an 03 2wd 2500 6spd, and I know about that shifting problem. I put a BD short shifter in place, now all I need is some way to move the stick closer to me ;-). Back to mpg, I went with ATF in the tranny for about 15000 miles, then back to 75W-90. Loosened up enough that my wife quit complaining (about that, at least ;-)). I run Rotella synthetic. I cut the entire bottom out of the stock air box, fitted same with a K&N. I got the front end aligned (which was way out, even though it never pulled). With just those changes, I could squeeze 24mpg on the hwy running 60 without the a/c. Then, the Banks kit went on, and if I can keep my foot outta it, I see 26mpg, yeah, laugh it up you unbelievers, that's at the pump and at my back pocket!

I too only get about 350 miles per tank, so watching this thread with great interest. I used to get 400 per tank, not sure when it changed exactly. I also have a new LP and IP in the truck, probably has 8k miles on the new IP.

I just filled up, and my mileage was 18.35 MPG with combined driving. Comp mostly set on 2, with some 3 and 5 settings.

My temp is 190 normal operating temp, with it going to 200 empty up hills. I relocated my blowby tube, but will try and wash the rad and cooler out.

I don't have the 4x4 and I am getting between 19 and 20 mpg
