6.4L Power Stroke oil?

[Engineer9860]

Is anyone using Shell Rotella in their 6.4L Ford Power Stroke?

My last company truck was a 2004 6.0L PSD. We had used Rotella and after many, many problems we switched to Motorcraft 15w40 at the recommendation of our Ford dealer. My current company truck is a 2008 6.4L PSD. We continue to use Motorcraft in the current truck. The reason we switched was in response to issues we kept having with the HPOP on the 2004.

Since the 2008 doesn't have an HPOP I'm thinking of switching the '08 to Rotella so I can use up some old stock I have laying around.

Has anyone used it? Should I be concerned by switching back?

Thanks,
Eng.

Between those two, use the one which is cheapest and easier for you to get. In other words, they're both great for your 6.4L.
