Does anyone know where to find compatibility charts for lubricating oils against metal materials.

Hans,
the first page of the link dont answer your question, but is a light in the tunnel wich will help you to find it.

A strange combination, since all lubricants I know are coming in contact with some metal.

The lubricants will rather attack non metals or alloys.

I suggest a search on google wih "oil-seal compatibility" or "lubricant compatibility chart"

The additives are probably the "agents" initiating the damage. One of the first thing I learned from a designer/engineer/equipment builder that EP Gearoil is a nono is you have copper rollers or bushings.
