With the new requirement for ULSD diesel and the new diesel motors that use particulate filters, there is a new motor oil that is MANDATED for them.
Older motors, like the 6.0L PSD can use the old (CI4+) or the newer CJ4 motor oil and the new diesel motor like the 6.4L PSD must use only the CJ4 oil.
The CJ4 oil (I am waiting for a synthetic version of this API rating) is too have better all around better soot contoling ability, better anti-shear abilities and more.
Here are several attachments showing the graphical differences or writeen improvements between the CI4+ and CJ4 oil specs.
