No, I think the world is down with a TBN of 3.0 indicating time to change the oil. Also, not understanding the need for boutique oil in a prosaic car (where Mobil 1, Castrol, Pennzoil, QS would deliver all day long). Also, not getting reusing filters. While we are here, the economics of performing oil change analysis on this higher-mileage, econo sled are confusing.
