The sample has a little chart that rates overall report 0-4 rating 0 being normal and 4 being critical. Yours is labeled 3 in upper abnormal and it stated fuel dilution has reduced the oils viscosity below grade. They recommend re sample at half interval from this current sample.
Assuming your are undeleted and running a tuner or?
sorry didn't see mods section etc.
The only mods to my truck/power train are the Amsoil dual bypass remote oil filter system and a K&N air filter, I also have train horns and more lights so it really stands out at night, if you can't see my truck at night you need to go to the eye Dr.
The day I submitted the oil sample is the day I changed the oil and installed the filter system.
I left on a 400 mile week long camping trip the next day and I've put another 800 or so miles on it since we got back on Aug 30th.
High fuel dilution in the 6.7L PS is a very well known issue, if you're mainly putting the miles on it from long trips it isn't as bad as if you are mainly driving around town with occasional highway trips of short duration (less than 100 miles). City driving also causes the truck to do more frequent regeneration cycles (DPF cleaning) that also makes your DEF tank to empty faster as a full tank is supposed to be enough to drive 10,000 miles. Because of the fuel dilution issues I will probably never leave the oil in the engine for more than 10-15K miles, and I've already gone from the 10K change interval that the manual says to use to 7,500 miles max.
Once I have 5K miles on the oil I'll submit another oil sample for analysis, hopefully it will have better results than the first one had.
I bought the truck in April 2016 and just today went over 15K miles on it. Being retired and on a fixed income means I have to save for camping trips, especially @ 10 mpg towing, diesel isn't cheap anymore. When diesel was over $5 a gallon I was really crying as I was putting 200 gallons in my Peterbilt every other day, I really miss that truck at times.
