Nothing...  I assume what you mean by "mineral oil" is the older
Pentosin CHF-7.1 whereas "pentosin" you mean the newer synthetic
Pentosin CHF-11S.  The new fluid is backward compatible with the
old oil (but the reverse is not true).

Please search the Audifans archives.  There are lots of posts on
this subject in the past.
