I use Rotella 15W-40 and change it every 3k miles or so with motorcraft oil filter, and change the fuel filter every 10k miles with motorcraft filters. I think if anyone is looking at a 6.4L they should get it. I know the early 6.4L might have issues but if you are looking at a job 2 or 3 truck I wouldn't hesitate of buying it. And if you have a pretty good relationship with a dealership then I would go ahead and do some mods to the truck. You won't regret it. You get the best of both worlds more power and better mpg. So I want to thank Ford and International of building a great truck. I'm really looking forward for the next 30k miles and many many many more.
My story is almost exactly the same, but I bought the truck with 44K on it, now have 69K. I use Motorcraft DMO, Motorcraft filters, (oil & fuel), and change them on the same schedule as you do. This truck is awesome!!! I too was worried about all of the negative talk, but in "Typical Ford Fashion" this truck does everything that I ask of it, and more. Hell I even pulled a tandem axle gravel truck out of the mud, and my 350 did not even break a sweat! Just wish I had someone there to take a pic. My next one will be the "Scorpion" though, I test drove one and it will definately do when this one get's replaced. (though that will be a long time)
