C-94 injector info
I tried to search to find a little more info on the C-94 injecter problems with not much luck finding my anwsers so here goes....
I have a 03/03 build that I bought with 20K, now it has 40k miles. I am very happy with the truck and have experienced no problems. (knock on wood) Is there a thread that I am not finding that will discuss whats going on with these.
Am I an exception that does not have problems with these injectors? Are there things I can do to extend the life/chance of future issues.....latest flash or fuel additives? Do others have this many miles with no problems?

Yes IMO there is help, I like running Mobile Delvac 1 oil, and a secondary bypass filter system (OilGuard) and keep you oil 2/3 of the way down the dipstick. Sounds weird but if the oil is to high in the pan it foams form crank wind-age. Foam has no lubricating properties
All of this is what I do, however there are no guarantees that this works....just my own personal way of helping my good-O-C94’s.

yes, the additives are good for inj. maintenance. This is unrelated to the C94 parts problem. Was there a connection here, or did I imagine it from the thread? The additives cannot correct part tolerances.

I don't remember any discussion of incorrect tolerances causing the problems with PI injectors. If that was all it was it would be simple to replace them. It is more than that.
The idea that overfilling of oil creating a situation where the crank beats the oil to foam to the point that the oil won't operate the hydraulic parts like the injectors and the VGT valve has been proven correct.
It is likely that oil foam is a poor lubricator and can contribute to advanced wear in all parts on these engines.
Injector addatives such as Stanadyne and Powerservice have proven (in our unscientific survey)to increase mileage by 1-2 MPG.
The fact that there are several of us with PI injectors with 25,000 or so miles without a problem might indicate that there may be connection (like Tim said)between PS/Stanadyne use, low oil level and synthetic oils remains to be proven.
In any event, it would be impossible to convince any of us that we are doing the wrong thing.

No, additives are generally a good thing. But increasing MPG on fairly new trucks ... I don't think I'd buy that. Why?
(a) good additives demulsify water, and pull it out, and eventually it comes out your water separator. If you measure MPG from tank-fill ... guess what ... your MPG will seem just slightly lower IMO. Because the separation also takes some fuel with it, but the water running through the engine, though damaging, brings slightly more fuel through with it.
(b) the chemical energy content in additives that is combusted does not necessarily help your MPG.
Now, in a fairly new engine, the additives are going to increase MPG by cleaning anything. Everythings already new and clean. The older the engine, the more potential for cleaning to affect mpg.
You will/should see more MPG rising from engine-break-in ... than anything else. I.e. if you never added anything, you'd probably still see your 1-2 mpg increase over the first 50K miles on the engine.
The jury is still out on the complete issue with the C94's. A fix was put in place. In my opinion.

WOW!!! IMO. However, I will tell you all something that is far from an opinon since changing Air filters' and since using PS in the grey bottle I've found 2 MPG on my combined mileage. And it makes me Happy. Except for the fact that So. Cal Diesel fuel is going up in price again.

Diesel fuel prices have gone up everywhere. There is a lot of speculation why. Instability in Middle East, problems in Russia, Venezuela, demand increases in Asia, the fact that we in the US haven't built a new refinery in years current refineries are running at full capacity, etc. Thank you bunny huggers.
