Just prior to adding this oil, I did a 30 mile rinse cycle with some leftover oils. I drained the old oil, added a frankenbrew of leftover jugs, took it on a 30 mile highway drive, then dumped it and added the M1 HM that's in this report. Seems like it might've helped drop the aluminum, iron and copper levels as drastically as they did, but the lead has me a bit puzzled. Any ideas? Particle streak or legit bearing issue? I guess we wait for the next report to see if it's an anomaly or a trend.
Previous oils from left to right: Castrol Edge 0W40, M1 0W40, ST FS 5W30.
The 1qt of make up oil this time around was M1 HM 10W40. Because of that, I expected the viscosity to be higher, but the 10.41 KV100 looks like straight 5W30.
