9200 miles on Quaker State Ultimate Durability 5w-30. For comparison I put up my January oil analysis on the same oil run on a 7000 mile interval. The OLM was at 30% at 7000 miles and at 10% at 9200 miles.

Based on these results, it looks like 8000 miles or 20% oil life remaining is the sweet spot for my car running this oil.

There were questions about the viscosity and zinc, so I asked the lab if there was enough to re-test. I'll know more next week.

Baron is high also, do you use or loose antifreeze? but it is sometimes used in oil as an additive

No antifreeze loss. I think it's just an additive in this oil.

M1 might have done a little better for me. I'll give it a shot on my next oil changes, and do a UOA on the second oil change of M1.

Also, this is on an engine that's been running the Trifecta tune for about 15-17k miles now, and was installed on both those UOA's. Wear isn't outlandish, and this engine's still on track to live a long life.

Syntec 0w-30 seems like a solid choice. I also wonder how M1 0w-40 would do, seeing how it's done well in European makes that are much harder on oil. If I recall correctly, both of those are A3 oils. Right now I'll keep using dexos1 oils while in warranty.
