its a fairly uneventful report, i changed oil & filter at time of sample and used the same type oil.
driving conditions are 90% highway with a little towing and hauling upto 4000# in the bed.
from what i have seen from my last two runs of 10w-30, powerstroke owners can run this year around without hesitation, weather conditions here over the last two months have been 90f+ more often than not.
