Hello to everyone,

I'm changing the oil on the above Compressor due a large oil leak. The Compressor is on a watercooled frimair chiller running on R22 with a set point of 7 deg leaving chilled water temp. The nameplate on the Chiller advises an oil called KYOSEKI, no other oil details are listed. Would I be right in thinking this is a mineral oil? Has anyone heard of this oil and could advise a shell/mobil replacement. Im guessing the oil grade would be quite high?

Any help would be very appreciated.
