I did it, runs great. I hope youv'e done some hard pulling to break it in. I run thw HDD 5W30 with remote filter and bypass. Tbob

No reason at all. There are some out there that feel that 15,000 to 20,000 mi is when your engine is fully broken in. I haven't seen any documentation on this from cummins and it would seem reasonable to me that 10,000 is sufficient. I have 11,000 and just changed w/ Delo at 10k but will switch to amsoil 15-40 when I hit 15k.
My reasoning is I'm going have my oil tested after this batch of oil has 5k and use that as a baseline to my future synthetic analysis. Amsoil charges around $17 to test oil and fleetguard charges around $13. I'm interested in how non-syn compares to syn analysis after 5k. And I'm going to use oil analysis to determine when I need to change my oil. I'll be changing my filter (stratapore) every 2500mi.
You should be fine. I recommend oil testing its a great way to quantify proper maintenance when/if warranty comes into question. Especially if you change your own oil.

Your good and broke in. Don't worry about it. When I talked to Amsoil the other day about fixin' mine up the tech said that even 5,000 miles would be sufficient provided you weren't putt-puttin' around. You can switch the transmission and rearend at any time. You'll be very pleased with Amsoil if that's what you decide to use.
In general, 5000 miles. This depends on the type of driving the truck is subject to; hauling or towing a load will shorten the break-in period. Light duty hauling or "babying" the engine can delay full engine break-in for up-to 20,000 miles.
Cummins recommends that you not use synthetic motor oil during the break-in period of 5000-20,000 miles, based on the type of driving, to allow proper seating of the piston rings. Beyond that mileage it is OK to use synthetic oil.
The use of synthetic oil would require that it be changed using the guide lines for oil changes set down by DC. Which means that you would either be changing it at 7,500 or 15,000 max
