Mine still has some white smoke on the initial startup of the day. Rough idle is gone. I'm going to go through a bottle of Howes Meaner Power Cleaner (recommended dose) and that should clean it up, I hope. I'm consistently getting 18mpg highway now. Haven't had that kind of mileage in awhile. I'm going to have to quit babying this thing and drive like I stole it.

My truck has been in the shop since last Tuesday. Bad #6 injector. Of course, non in stock and had to order it. As of Friday afternoon, status on the shipment only said "inroute to UPS".
This really stinks that it takes so long to get a part. I'm tempted to go take it from them Monday and go have some DDP 50hp's in. Then write a letter to CC............but that wont achieve anything.

things don't make sense
My truck gets fired off around 5:30-6:00am and gets shut down 7:00-10:00pm every day, with periods of hauling 20-26k lbs for +- 1.5 hrs. and sits idle for 1hr. at times I get a rough idle during the day but even with all the idle time I am getting 8-9 mpg if I shut the truck down while loading and unloading i get 5.5-6.5 mpg.
the "tech' @ the local dodge shop whois a "level 4 "( what ever that means) told and showed me how long i spen in the 0-10% of HP usage (65%) of my time according to his little 'puter.
he said that DC would frown on that data if there were any sort of issues with the engine( least of my worries)
I quit shutting down while loading and loading and i am still getting 6+- mpg
PS
the mpg figures are hand figured( as if there were any questions
)what do i need to do to increase mpg???????????

The reason for your bad fuel mileage is all the idling. Your using fuel without moving. If the engine idles for "X" amount of time and uses 1 gal. of fuel you don't have any miles on the truck to account for that gallon of fuel you just burnt idling. If you shut down the truck after every run (after letting the turbo cool down of course) I'd bet your mileage would improve. If you just keep idling the truck you won't ever see an improvement. Your bad mileage is just the nature of the beast.

I THOUGHT THAT I SAID THAT IT WAS BETTER WHEN IT SAD IDLE INSTEAD OF SHUTTING DOWN WHILE LOADING AND UNLOADING. SO WHA DO I NEED TO DO TO GET BETTER FUEL MILAGE.
I AM GOING TO TRY TO KEEP BETTER RECORDS FOR THIS WEEK AND SEE WHAT MY FUEL CONSUMPTION PER HOUR IS ; I AM THINKING IN THE NEIGHBORHOD OF 3-4.5 GAL/HR

No I am talking about start to finish - daylight to dark - fuel consumption idle time + pulling time. I think that starting and stopping in town is one of my biggest setbacks B/C I was getting more mpg on the longer runs than Have been on the shorter ones.

Bringing this back from the dead. I had to take the truck back in. 2 more injectors down for a total of 4 in less than 23,000 miles. Same symptoms as before so I knew what it was and I was right. This time I caught before it started getting really bad. It's the only problem I've ever had with the truck so I'm happy.

This is a very debatable topic here. These 06+ trucks seem to be a hit or miss with injector problems. I have a early 06 with 65k on the clock. On a cold start up mine will occasionally smoke white for about 5 seconds and very rarely have a little stumble during the smoke. It has done this every since i bought the truck with 27k. The way i see it is this: If your not making any oil every oil change, your truck runs and idles fine when temps are normal you are fine. Also i hear adding pressure boxes on these 06+ motors are asking for trouble unless you have aftermarket sticks and proper filtration.
JThiessen with the symptoms you are giving i'd say it's time to get some Flux's.

A lot of people are VERY QUICK to state it is an injector problem. That is totally UNTRUE & a lot of times without merit!
There were many posts here that were more "reasonable" and talked about the heater grid and cold startups. There is a temperature range that the trucks are "finicky" with. If it is cold, the grids activate, the truck starts fine. If it is around 45F-75F, the grids don't come on sometimes, the truck will smoke and idle rough as it is still "too cold" of an intake charge.
I just don't like the "fear mongering" that goes-on sometimes when people have issues like this. White smoke on start-up does not equate to "melted pistons" and "leaking injectors that will fill your crankcase with fuel and destroy your engine". Can those disasaterous things happen? Yes, but it is NOT that common and stating those types of replies scares the poster, gives our trucks a bad name, and causes undue fear & worry.
Diesel engines are a different beast compared to gasoline engines. We have engines that run loud, smoke, idle rough, smell. Things guys love!
IF it was an injector, like the diesel mechanic stated, you would have long cranking times. Due to the fact that the leaking injector is filling your combustion chamber with excess fuel, now the engine is trying to ignite that fuel and it cannot, so the engine does not "fire" until some of that fuel has dissipated. It is sorta like "flooding" a gas engine. You must crank it over numerous times to get rid of the excess fuel before it fires.
So, IF you had:
1 - long cranking
2 - increased oil level (due to fuel contamination)
3 - running rough when warm, hesitation, violent misses, bad acceleration
4 - smoking ALL the time, even when warm
Then YES, I would say it is time to take it in, as the signs show it might be an injector that is bad. The one poster who stated he had the same symptoms as you and it WAS an injector. READ HIS SIGNATURE. He has TONS of engines MODS.(Twin turbos, numerous fuel & power stacks, etc.) That makes a HUGE difference compared to yours.
You gave only ONE symptom, white smoke on start-up, and then all of a sudden some people posted the most absolute, cataclysmic, fearful, dreaded responses.
That is where I find a problem with such quick and unmerited responses.

You RULE and are TOTALLY RIGHT!!! I was looking at this thread cause i can make my truck blow white smoke like a mother if its between 50-75 degrees at start and i hammer on the gas b4 the trucks had a chance to warm up at reg idle, and kinda got freaked out fer a sec till i read your post.... thanx fer making a stink about that for all the knowalmostnothing guys that enjoy our beasty trucks and come here for help..........
oh and btw, this comment comes from a 96 owner, but after reading everyones posts, my boss has all the testing equipment nessecary to do injector tests,so one sunday im gonna just check it out, cause now im paranoid... rofl
