About 25% towing. I changed the air filter , probably accounts for the dirt.

Overall a good sample IMO. I don’t like the fuel dilution but I’m not familiar with the Power Strokes. I try to keep my Cummins below 2%.

Just my $0.02

Higher fuel dilution shows up randomly in my uoa. Next one it's likely to be lower, I speculate it matters when you take the sample. Could be this sample was right after a regen (I don't really track all of them). I won't really start worrying about it until it becomes a trend.
