I'm pleased to see wear metals continue to drop...although there isn't a lot of room to go lower. This drain interval saw a tough winter combined with a highway trip from Northern Michigan to Western Colorado and back.
This appears to be the drain interval that gets me the maximum mileage without taking TBN lower than I would like.
This engine is excellent. The MI-CO trip was 3795 miles, average fuel economy 18.0 mpg.
