Look in the valley of your motor for fuel. Sounds like the infamous drain leak.

yea fixed that that bumpped me up 1mpg to 12.5 on the next fill up then i got 9.6 on the following

edit: i have been running the 80 economy dp tune i got the dp around the same time as the fuel economy took a dump. i have been trying to figure out if they are related or not. i filled up and am running it on the stock setting now, my summer fuel ecomomy was running a quadzilla

Its all stock except for a stack but i have a TW on the way so we'll see how that helps...if i can keep my foot out of it long enough to get an accurate measurement :D

ya i really do use around 4 gallons of oil per tank, i have a connection with team petroleum, Not on every tank but most tanks i use a lot of oil
I don't care if you get the oil for free you are wasting it and I call BS on your MPG :blah::blah::blah:

18-19 here, with 4in lift and 35s, but usually dont go over 70, but I usually do get to 70 quick:D about 50/50 highway city, I would say I might be able to get 21 if I babied it all the time, which is what my dad gets in his bone stock 250 2wd auto, but i mean dang I do like a little excitement. I've heard that red dye gives you a little better economy, but of course i've never done thatLOL

Forgot about this thread...with the new tuning I bumped up to 20.4 MPG mixed driving. Up about 1 MPG overall from my last tuner.

The ONLY thing that changed was the tuner. Nothing else, so I think it was worth the switch for that alone...
