New 6.4 should be here soon and my question is the best way to break it in? I have owned 3 Dodge Cummins and this is my first Ford Powerstroke. With the Cummins the first 1000 miles was pretty much take it easy and after that you turned it loose. Pulling loads was recommended for good piston seating and occasional red line was good. The Cummins never let me down so I hope I have the same experience with Ford. Feedback would be helpful. :

Read and follow the owners manual.

Also if it's an automatic I would avoid coasting and idling for at least 500 to 1000 miles. You can do this by using the tow haul. Keep the rpm's low for the first 500 miles. Don't tow anything for the first 1000 miles.

Avoid long idle periods even after breaking it in. Idling is bad for any diesel.

All my touring photos. (except the two massive trips in 2011-soon to be posted eventually)

Coastal Maine road trip 2007

Alaska tour 2008 - 14,000 miles in 28 days

Replaced "The Beast" 6.4L with 75,000 miles. Hated to see it go.
