Phillips 66® Syncon R&O Oil (ISO VG 100-680) is a premium quality, synthetic, rust and oxidation (R&O)-inhibited circulating oil developed for use in circulating systems, lightly loaded enclosed gear drives, and other industrial equipment operating under severe-service conditions or at extreme temperatures. It is particularly recommended for use in applications where operating conditions may be unfavorable or too severe for conventional mineral oil-based circulating oils.

• Plain and rolling-element bearings operating at very high or very low temperatures, and sealed-for-life bearings.
  Lightly to moderately loaded enclosed industrial gear drives that do not require a compounded or extreme-pressure (EP) gear lubricant.
  Circulating systems of paper machine dryer sections and calender stacks.
  Industrial blowers.
  Industrial worm gear drives with bronze-on-steel gears.
  Reciprocating air compressors where the manufacturer specifies a PAO-based lubricant (ISO VG 100 or 150, typically).
  Lubrication of the upper cylinders of gas compressors handling natural gas or process gas (ISO VG 150 or 220, typically).
  Industrial equipment operating over a wide temperature range where an inhibited mineral oil is recommended.

• Please refer to the attached Safety Data Sheet and SPEC document for more information.
