Checked out some bad injector/bad ficm startup videos on youtube and the good news i guess is that my truck is not nearly as bad to start/smoke like them so i guess thats not it....my truck will idle fine it was just that little bit of white smoke that got me worried. Is that a sign that it will eventually turn into that?

Wonder if maybe it's stiction? Maybe try running revex or archoil in your next oil change and see if it helps any

Little update: ran the looney fuel and was getting 8.5 mpg as opposed to my 10mpg on the regular looney?!!!?!? Switched back to the looney now and getting a consistant 10-11 on the dash. Ran my buddys scangauge 2 and all my numbers were fine. Why would the looney fuel have worse mpg? Help

Had a couple hundred pounds in the truck and got 19mpg. I might be sold on diesel kleen

Before injectors work and 4 bad -17mpg
After work with some atf in tank - 16 -17
Diesel kleen 19

Id like to try optilube on the hwy because when i had it in the tank i got 16 hwy/city.

How aero dynamic are out cabs. I heard tail gate doesn't matter up or down. Weight though.

I use the #road trip le app for iPhone and I am averaging about 11.5 mph. The in dash display is close to this, within .5 mpg.
Airaid filter
4" lift
35" Toyo mt's @ 50psi
Amsoil full syn oil
Current fuel add is the XDP brand. I used diesel kleen last time and was getting 1mpg better.
Truck is otherwise STOCK.

You know, I'm not feeling so bad about my MPGs after seeing this thread, I actually feel a little proud of my truck

I haven't run any diesel kleen or any other fuel treatments, and I've got a bunch of junk in the back of my truck. Damn, I bet if I started running additive and cleaned out the truck, I might have the highest MPG 6.0 around
