I know this topic has been discussed extensively, but I wanted to poll you
knowledgeable folks as to whether you can mix the mineral and synthetic
versions of Pentosin.  I've got a leaking high-pressure hose that is being
replaced.  I know that the label on each carries a prominent "Achtung!" and
I've heard that mixing the two will turn the seals into mush.  However, my
mechanic is telling me that there is no problem mixing the two.  Currently
I'm running the synthetic (11S) version, but the shop only stocks the older
kind.  Any advice?   TIA,
