It clears up once oil temps reach 20f, not any time related but that's usually 30 seconds. My truck has 222k KM or just short of 140k Miles I suppose. Not stiction issues that I know of, just prevantitive archoil.

 

I really don't think your weather is causing stiction, most likely the oil your using... What are you using?

8 injectors every year or every other year is enough to make me wonder what's wrong and then do some research, but to hear someone tell me it's the weather.

Thanks for the business Ted, see you next year and oh, by the way, injectors are going up, something like an extra $50 dollars each since we change out 8 at a time on every vehicle that comes thru the door... the weather here is a killer!

Man, that Ted.. we love that guy, 8 injectors every time he comes in... What's Up Dave, long time no see... whats it been about a year.. hows the wife and kids?

I'd be thinking twice about going back to that shop.

 

Sorry I think I may have wrote that wrong. By no means am I saying they are replacing them each year! That would be a great way to make money... What I mean is that when they see trucks that have stiction issues from their experience its best to replace them all. They can only speak from their experience. But they used to do just the Injectors that were sticking(like everyone else) but they were getting comebacks within a years time(sometimes sooner) that the other injectors started sticking. They believe with the winter climate and such that it takes a big toll on Injectors. When there's one sticking the others have to work harder. This is exactly what happened to me. I replaced 3 and within about a month what they said happened. The others started sticking. And my fuel pressure, ficm, battery voltage checked out-they do those tests before Injectors. So to be more fair to the customer they really push all 8, because they are paying for labor once(most likely a one time thing for each vehicle). So absolutely not are they putting in 8 a year. If that's how it sounded I apologize. It's just their experience that's the best way to go. I'm guessing warmer areas this is probably unheard of.

Also the oil I'm using is t6 5w-40. Definitely the way to go

 

Don't apologize...
I think that stiction can happen in any location and that using synthetic oil can stave off the inevitable, not cure it. Oil is cooked on, not froze on.... the weather is total crap!

You come in, they hook the truck up and see that your injectors have a contribution code for low performance.. it could have been low fuel pressure, FICM or a number of things that killed it. They surmise that it is probably stiction, because its a 6.0 and see it all the time, read stories of it, they even make additives for it.

Easy sell... I'm in there already, saves me the effort of pulling a valve cover later and you the cost to not have this issue for a while, I'd have to charge you to pull the cover later, we HIGHLY recommend all 8.

Most would say, that's interesting... well, if you think that's the way to go. Mechanic says heck yes, I would.

A $2oo injector, core charge and labor for one... $600

OR

$3000 for all 8, cores and labor...... $3800

He gets his money, a BIGGER job than the initial quote and you get a feeling that they are covering your butt... great guys!

It's heard of here, discussed to death and probably mentioned anywhere a 6.0 comes in for shop work, tests reveal low contribution... you've got stiction!

It isn't his money, no way of really proving that it was stiction and the test revealed bad injector.

I'm going out on a limb.... your going to need injectors at some point, tomorrow, next month, next year, it will happen. Stiction is a known "hot topic" and the mechanic knows that, anybody who owns a 6.0 knows that. New injectors are going to make the truck run much better, no question about it. Pull up the screen to watch the injector contribution graph (the mechanic can), cold truck, first start deal.... see the graph of the low injector and after a little run time, it begins to act more normal and comes into line with the others.... bingo, stiction confirmed.

It's happening now and will happen to the others, lets do all 8.... your coming back, no doubt! Your coming back because your not going to do the work yourself... why your there to begin with. That flat tire you brought in has a nail through the sidewall and needs replaced... but since it's going to happen to the others, lets just do all 4 tires now.... would you buy that? At least a thousand threads here that start with "I brought my truck in because its blowing smoke" (from a ruptured EGR cooler) and get told the heads are toast... because 6.0s are known for that, head gaskets... they are really known for misdiagnosed EGR coolers diagnosed as head gaskets.

If he really knew his stuff, he'd say... that one right there is a problem and because these motors compensate for that issue by giving the others a little more fuel to bring it up, we'll replace that one and watch the others, they are working just fine.

You may have never needed them replaced, some guys go 200,000 miles on a set...
There are hundreds upon hundreds of threads here with the same response.. the dealer said, do all 8. ITS A GREAT WAY TO MAKE MONEY!

Have you done the blue spring upgrade? Low fuel pressure kills injectors, anything lower than 45psi can hurt an injector, wide open throttle can drop fuel pressure to under 45psi (with stock spring installed) and may have been the root cause... he never got that far, your coming back, he's counting on it.
