Proper break-in for the 6.7l

[kwak12r]

Hello everyone.
Just bought a 2011 6.7L. Traded in my 2002 F250 7.3L

Been looking for proper break in procedure but can't seem to find any info other than what is in the manual.

How did you break in your 6.7L?

I drove mine non stop (except to get fuel) for 850 miles, then hooked on to 15000 lbs of trailers and drove non stop for another 850 miles then added another 4000 lbs and headed into a strong wind and drove non stop for another 1400 miles. It worked hard enough to bring the fuel milage down to between 5.5 and 6.5 miles/gallon and made the transmission shift down two or three gears on every hill. I'm thinkin it might be broke in.

Why would there be any need to do something in addition/contrary to what the manual states?

Agreed! Drive it like you would normally, that's how we break in all our BMW race engines

I'm gonna drive around normally for around 500 miles and then hook up my camper and tow it 1200 miles.

I was reading something and it said change transmission fluid / filter at 150,000 miles. It that what the manual says?
