Well, all I know is that this occurred shortly after using MaxLife. As most on here know, I've only used good oils and very moderate drain intervals throughout the life of this motor. I never went past 12k miles per drain. Usually 8-11k, sometimes less.
Can't explain it yet. If this current fill doesn't clean it up, I'll switch back to Mobil 1 HM/M1 mix or maybe their 0w40.
