Once again, high fuel in the oil and lowered viscosity. Oddly enough though, the iron per km is lower, silicon is lower, lead is the same and only the Copper has went up.code:

Any ideas? Do I have a problem with the injectors?
The truck runs great, no romps or stumbles or hesitation. I can't tell from the dipstick if there is fuel in the oil.
My driving habits are: on Fri and Sun I distribute and pick up signs at various intersections, for about 8-12 hrs per night, 350km per night. So I drive to one intersection, stop in park for 1-3 min, put/pick up the sign and then back in to the next stop. The stops can be 50m away or 500m away. But I also do regular street driving and hwy driving during this time so it's not a straight 10 hrs of stop and go. During the week, it's "normal" driving, mixed city and hwy.
I'm going to request that Ford checks the injectors but I'm afraid they will say nothing is wrong and that this is "normal" contamination for vehicles that idle more than "usual"
Any ideas/suggestions? Why would I have lower wear with so much fuel and lower viscosity?
Is idling in Park different than idling in Drive with the brakes on?
