York S Oil Lubricant

“York S Oil” typically refers to a specialized synthetic refrigeration/compressor oil used in York chillers (a brand under Johnson Controls). It is formulated for:

• High-efficiency lubrication of York screw or centrifugal compressors

• Stable performance at low temperatures

• Chemical compatibility with refrigerants (such as R-134a, R-1233zd, R-513A, etc., depending on the chiller model)

• Long service life and reduced sludge/acid formation
