Decided to take advantage of a free dealer oil change, and as you can see from my results, am regretting it. This OCI did occur through an abnormally cold winter and spring and it did do a lot of idling. Miles were probably 50/50 city/highway. Filter was new Fram Ultra. OLM was at 1% remaining. The two previous samples were with PUP 5W-20.
Dumped the oil and refilled with M1 EP 0W-20 that I scored for $14/jug. Curious to see if the iron drops back down next sample.
