Heres mine, and I use Rotella Syn 5w-40 too. This sample was after an extended regen cycle where I could not, because of time constraints and things I needed to get done, get on the highway and drive needlessly until the regen process finished. I was in town and the cleaning started up after every stop I made where I had to turn off the engine. I think I made like 7 stops that day over a period of 6 hours and I remember thinking how bad my fuel dilution might be. This was taken at 41000 miles and the mileage was 6100 on the oil. Thats one of the aggravating things about these things, when you dont have the time or ability to get on the highway every time it goes into regen you have to just drive around letting it start up and stop, and then restart until it finally gets the job done. I liked it before when it would just go into regen and clean the filter even when in park.

SCOTT: Wear looks pretty good in the first sample from your Power Stroke, but we found fuel and the possibility of coolant contamination. Fuel at 3.0% is in our cautionary range and lowered the viscosity slightly. This could be related to something in the regen process, so we suggest having this checked out. If you are gaining oil on the dipstick, then a problem exists. Potassium may point to a coolant leak, and this may have something to do with the fuel as well. Watch for any loss of coolant and check back in another 6,000 miles to monitor these findings.
