Hit 500 oil samples on my shop truck last week and the one number that got me was 3
Three of those samples came back with coolant in the oil, all from the same 6.7 Powerstroke customer who swears he checks his levels every Sunday. Any of you running a set interval on sample testing, or do you just pull one when something feels off?

Every oil change on my fleet trucks, caught two head gasket leaks early that way.
