Did you notice poor gas mileage before you had the repair done? as you all know the best mileage I ever got 12 mpg and for the past month or so I am down to below 9 mpg. I just found out today that I have an engine misfire code from 280 miles ago, from reading all your posts it seems that almost all of you got the same code also. Just wondering if this could be the reason I have always got bad gas mileage.

 

Now we've got 3 "head/Valve" threads I have to keep up with? GRRRRRR [sm=alcoholic.gif] Killer, I was on a trip when I had my prob happen - therefore I was checking gas mi. closely. I averaged approx 15-16 mpg the whole trip until I could get home to the dealership. 9-12 MPG OMG!!?? Uh could it be the way you drive? <just askin> If not..WOW how bad for you...might as well be gassin up that big ole #2 hog! (One big reason I chose to go 3..didnt want to go broke in gas alone!)

 

I thought it was my style of driving because I hate getting passed[:@] But when I was in the hospital a few weeks ago my wife was the only driver of the truck and she got 9.5 mpg for the entire week, so it can't be me. BTW...my wife drives like an old lady....well you know...like a woman J/K!!

 

Yeah, so does the hubby when he gets in it...so I don't let him drive it much![ [sm=nothatway.gif]

 

Below - find my mileage - do understand i fish on the beach, so mpg may be down due to the 4x4 factor... this is PRE-VALVE issue...

wow..those numbers are alot better than mine ever were

 

Yeah, I am pretty psyched...

It is the 06' Adv and Lux package Automatic (kind of wish I had the stick)...

Was getting 13-14 with my LR

 

My mileage was slightly lower than average when my light came on. My lowest mileage was a few tanks before that, and I think that was probably still breaking in.

I am actually hoping my heads go and soon...my mileage is terrible and getting worse and no dealer seems to be able to anything about it. they all just say...due to larger tires. I asked the last one if they could check the pcm and see if there is something out of whack or maybe flash it and i was told there is no flash available and that they couldn't do anyhting with 35" tires on it. I called three other dealers and they all gave me the same crap. I just filled up again tonight, went 187 on a full tank, filled up with 20.4 gallons---9.16 mpg...impressive. [:@]

 

What you might want to try, to prove your tires aren't the prime culprit in your mileage is to go out and get some cheap 33's to put on, run a couple of tanks through while keeping serious trak of your pre and post tire change fuel economy, then go in and say WTF with the 33's on.

Also, I was thinking, aren't you the one who only puts $20 in at a time, and only when the tank is empty? If so, try actually going from full to something less than full, then fill back up and not the mileage traveled. This will be more acurate then guestimating. If not, sorry for the confusion.
