Maybe I'm hard of reading, but I couldn't find what the recommended breakin period is on the 08' Expeditions? I'm guessing that it's 1000 miles, no constant speed for > 10 minutes, no more than 3.5K RPM's.
I have never followed the break in period after the first 250 miles, after that everything is pretty much good to go. Heck we take our F-550s w/ 8 miles on them and load them to over 22K lbs and run them that way for 80K miles. Haven't had a transfer case or axle fail. Engines crap out all the time but thats the 6.0. I think break in periods are a thing of the past.

Did you ever try following some type of break-in procedure? Maybe the engines would live a bit longer. Just curious. The 6.0 certainly seems to have its share of issues, but I've seen some with well over 100K with no problems. Just sayin'....

I've always been told to break it in the way you intend to drive it.

"BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer. For more detailed information about towing a trailer, refer to
Trailer towing in the Tires, Wheels and Loading chapter.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating. See Engine oil in the
Maintenance and Specifications chapter for more information on oil
usage."
It is really amazing how many people do not read the owner's manual. Who knows why, but it's a fact. The owners manual has almost everything that you need to know about your vehicle. Its a big book, owners paid for it, but it wastes away in the glove box or in the trash. Too bad.
Rich,
Thanks for pointing it out for me. I did read the manual, and even took the time to find something on the breakin period, but obviously overlooked what you posted. Thanks again.

Who would have thought that there was no section for it and it was in the introduction? Who reads introductions anyway? Well, me because at NHTSA we were alway ranting about owners not reading their manuals and calling NHTSA because they didn't know why their vehicle did this or that.
I suppose that I am too **** sometimes! I read everything that came with the vehicle and I am part of the way through the shop manual.
Rich, does the manual state normal and maximum operating temperatures?
If you can look it up, I’d like to know about; Cylinder Head Temperature, Transmission Fluid Temperature, Engine Coolant Temperature, and Engine Oil Temperature.
I’ve got a MSD Dashawk monitor and can look at everything except for EOT. I’ve got some datalogs stored in the unit that I haven’t downloaded yet from a travel trailer tow I made last week round trip Phoenix to San Diego.

The shop manual says nothing about temperature other than using it as a criteria for testing, ie. with the coolant at least 152 degrees, then test the xxx system.

The oil from the factory has a dye in it that only shows up while looking at it with a black-light, they do this so any leaks can easily be found. They say the dye will not hurt anything, but in any case I change my oil to full synthetic at 1k miles even though the warranty did not require it until 7.5k miles on my 08. Note: I am using Full Synthetic and not the factory installed Synthetic-Blend, there is a big difference. Oil change intervals went from every 5, 000 on 07's to 7,500 miles on 08's
