Reply to "4-Ball Wear Test- Slick Marketing ?"

The 4 ball wear test under ASTM D 2266 indicates the EP/antiwear property of a Grease. The method clearly is for grease.

If Amsoil is using this test, or its variants, as a gimmick for Engine oils, I fear thier Oils become grease over a period of time. I would not like to patronize such oils.
