It would be nice to check the HTHS on some of these oils, especially those who apparently only give out the category minimums (Castrol).
Do any oil analysis labs run HTHS on new oil?

Well, HTHS is an ASTM standard test, not a run-of-the-mill oil analysis test.
Specialized labs with the ASTM test apparatus will run this for a good price.
Good price for the seller. Oh well, I kind of figured. Thanks
