To me, the real value is doing oil analysis over time. You start to see how your engine is holding up. Also, as stated, always get a TBN done if not standard. This shows how much of the additive package is left and in reality how long you can go on the oil. I have had good TBN numbrs at over 15,000 miles with Amsoil's best. Will be interesting to see the numbers on the 370 when folks start doing tests with some miles on them. Perhaps we will learn more about the effects of any high oil temps.
