No coolant mixture, as I stated "in a well maintained engine" at the time of that picture. Pressure testing, and a UOA indicated a healthy engine, with no coolant in the oil. I gave it to my son with 100K on it, and it went to about 150-160K miles when my son replaced it with a new Hyundai Accent in late 2017. Situation resolved? The synthetic oil had done some cleaning, although it was nowhere near as clean the OP posted. My point was only to show how someone who follows blanket statements might find they aren't always correct, and why I always take them with a grain of salt. Long before my Bitog days.You are saying this engine went many more miles and the situation was resolved using synthetic oil? That color shouts coolant mixture to me.
