HTHS was tested in the late 1990s on non-formulated oils. In this isolated case not related to formulated oils a wear scale has been shown. Tests done today with formulated oils show little, if any, relationship between HTHS and wear. This is why some people are swayed by the inability to understand the significance of individual scientific articles. The whole article must be understood in order to make reference to engine wear patterns.
I will review with you some recent related articles that I just do not have the time to go over critically at this time.
