Tallpall...the 6.0 is the Diesel 365 from International isn't it?

Didn't Ford send out a TSB on running the new 365's on 10W30 diesel or something? Just asking.

I'd stick with Rotella (Dino for break in, Synthetic after 10,000 miles) or Delvac. I'm a HUGE Motorcraft fan...but those two diesel oils cannot be beaten.
