Research indicates that fuel dilution is intensifying due to
the use of in-cylinder post-fuel injection during the engine’s
exhaust stroke to regenerate the diesel particulate filter
(DPF).
this aint good but if a feller runs good oil with a decent flash point everything will be fine...........also another key to flashing off excess fuel in the oil is a feller must bring the motor up to operating temps for a minium of 20 minutes so the oil can do its job, big mistake with some folks running diesels on short commutes.........JMHO

Just a little more info on this matter for you.
Again, this can be a concern with any 07-10 ford 6.4L, dodge 6.7 and chevy 6.6 with the DPF in intact. It sounds like for the engine exhaust to do the passive regeneration, you need temps of around 1100 degrees, otherwise it will use the fuel.
There's some good and not so good news for the 2011 model and this may not be definite yet. Dodge may be sticking with the cyclinder injection. It is also going to be used for the NOx coverter, so more fuel may be used...not good.
Chevy may be swithing to the 9th injector in the exhaust so could eliminate this issue.
Ford not sure yet.
Looks like I'll be sticking with my 05 for a while
