FUEL DILULTION.....DPF
I am getting constant fuel dilution, no matter how I drive, how long inbetween services, I think its the DPF that is causing it, I am thinking about having it professionally cleaned and or replaced and then drive and resample and see what difference I get

Fuel dilution can be from a couple of factors..not the DPF itself unless you are having many regens.
Typical regens for a 6.4 can range anywhere from say 90 miles (usually due to heavy towing) to the backstop mandatory regen of 630 miles.
In town regens will produce more fuel dilution then on the hwy or towing regens.

yea see we are in town driving, some hwy to each job, then on the job low speed driving, idling, start and stop, usually we have enough hwy driving to get things up to temp and hot and running like they are suppose to, we try not to shut the truck off while it is in regen. but I have several trucks that are getting up to 10% fuel dilution! several times in a row. I am running around 160 hours/4000 miles a service, see oil sample report (the miles/hours on the report are wrong) I am just trying to find a solution to the dilution, I am preaching good driving habbits, reduce idle time, don't shut down while in regen, serving early, we are doing everything we can be doing to prevent it. our application of these trucks isn't really what they designed for, these trucks are designed to run hot on the highway back and forth lots of miles long trip times. so I think its time to start trying cleaning the DPFS and see what results we get.

As a mini fleet owner what you need is a manual regen that you can do yourself before the truck leaves out for service.
There are a few out there now that can plug into the OBD port and do that.
Deleting the emissions is probably the only other cure.
Be sure you are changing the oil at 5K intervals/hours so that you keep the upper end wear down.

very good point, we have the capability to do manual regen, we could make it part of the standard procedure on a service to do a manual regen, and yes we never exceed 5000 miles, we are usually 160 hours/4000 miles or less. we usually hit the hours first.
