It's not that much of an inconvenience to use a fuel additive each fill up, especially if you plan to keep the truck for many years. Why take the risk of having a fuel injector failure after the warranty runs out when you can use an additive to increase lubricity and (hopefully) increase the life of your injectors.

I have an 03 6.0 w/120000 miles and was having EGR problems at 80000.
After disconnecting it 40000 miles ago I have had no problems at all , I still get high idle when cold and my oil is still clean at 5000 mile which never happened before.

The reason (mine) for the EGR knock off is this (and if theres a chance it is still open, then its going to be "modified" so that it is definately shut)
We pay quite alot for air filters, quality oil, fuel additives etc etc and then, we let a % of exhaust gas back into the intake manifold? Burnt diesel. I know why they do it, but it makes no sense from a life expectancy stand point.
Maybe it does no harm, maybe it doesnt contaminate the oil, maybe, maybe.
Heck, why should I care, I have a 5 yr, 100k warranty. The reason is I absolutely loathe anytime my truck has to go in for service (my last one had a persistant pinging problem, and rather than try and fix it, I sold it) I loathe service departments. Sooooo, if I can help my engine stay clean and healthy, I'm sure going to try

To LVEILLON's question:
"Again...What are ya'll wanting to achieve by disconnecting the EGR?"
Zero shop time and longevity.
My EGR Valve was disabled immediately after being replaced when I got my last re-flash about 14 months ago. Therefore, I am extremely confident that it is closed.
Keep in mind that I have only advocated the disabling of the W. A. R. T. on '03 / '04 6.0 engine builds.
FYI: My truck never blows smoke...at any time. Clean as a whistle....But, I also use PowerService @ each and every fuel up.

I think using a fuel additive is just as important as buying fuel from a quality station. I'm curious to see the setup on the new 6.4's when they hit the street.

From what several of the FORD techs in the forum have reported is that crappy cheap fuel is a main problem and too much idling. The HighIdle mod greatly helps this. Also use of a fuel additive is best.
