Thanks for that; I was considering getting one done, too, but never got around to it. I like how Blackstone says it's a little thick for a 5w-30. Given that it's an CK-4, E6 lubricant, that should be no surprise. That's a lot of boron, and I'm not surprised about there being a fair shot of magnesium, too. You didn't get TBN, but that's supposed to be 11.0.
