Well... Even tho I don't think the break in is done yet.. But I've noticed for a couple weeks now.. MY gas has lasted a decent amount of time.. Basically 1 tank a week... Pretty good for me... But I fill up Thursday mornings and it usally lasts... but this week .. I filled up thurday and As of 2 nights ago... I only had a half tank left... I know i did extra driving.. But i did'nt think enough to burn an additional 1/4 tank of fuel... Will this fix itself? or is this how the Hemi works?... Any help would be nice.. Thanks...

 

When I got my truck brand new july 06, I got 10-11 mpg. I drive the same as I did then now (7000 miles) and i get about 14 mixed. But I can get 21 going 65 on the highway. Let it break in some, possibly consider a tuner. I know my fuel mileage went up when I got a Superchips and put it on the 87 economy tune. I always run it on the 91 performance tune now though, never know when a guy in a f150 might try to make a fool of himself.

 

yeah my truck was the same way...when i first got it, it was only gettin like 13 around town...now (47000 later) it's holding steady at 15-16 in town and avg 20 on the highway doin 75

 

LMAO, You dont need a tuner to put an *** whoopin on a Dorf!
