I just sent in another oil sample to 2 separate labs. They are both doing TBN, & soot, along with the regular testing. Will be interesting to see what levels of soot in the 2018 3.5 Ecoboost, & variances between the 2 labs on the results.
This is my 3rd oil change, & analysis in 12,670 kilometers. Fuel dilution has been my biggest concern.
