You may well be a retired mechanical engineer,so is my dad and neither of you are oil exerts. Engine oil attracts water fact. Engine oil left in my shed open goes milky fact. Engine oil open to the air especially small amounts like in a turntable bearing goes milky and like in my bearing that milky goes brown milky as rust sets in. The motor oil did not harm the spindle it was the water that formed the emulsion due to the emulsifying agents in car engine oil. THIS is what pitted the spindle and THIS is the reason car engine oil should not be used in an open bearing.Chris, I'm a retired Mechanical Engineer. I spent 40+ years in the automotive field, and have quite an extensive knowledge about motor oils and lubrication.
If you had a steel spindle that was dissolved somehow by a motor oil, I'm sure there is some engineering firm that would pay you a great amount of money for that piece of steel. Or send it to ESI and associates, a metallurgical firm west of Chicago. They would love to have evidence of steel eating oil.
That would put snake oil to shame.
