Phillips 66 Syncon R&O Oil ISO VG 680 Synthetic Lubricant 

Phillips 66 Syncon R&O Oil 680 is a premium quality, PAO based synthetic, rust and oxidation (R&O)-inhibited circulating oil developed for use in circulating systems, rotary air compressors, 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. 

Phillips 66 Syncon R&O Oils have the following benefits: 

  • Outstanding resistance to thermal breakdown at high temperatures 
  • Outstanding oxidation resistance to minimize sludge and varnish formation 
  • Protects against wear 
  • Protects against rust and corrosion 
  • Good water-separating properties 
  • Good foam resistance 
  • Excellent low-temperature fluidity 
  • Low carbon-forming tendency for use in rotary air compressors 
  • Extended service intervals compared with conventional mineral oil-based lubricants 
  • Compatible with mineral oil-based lubricants 


  • Rotary air compressors where the manufacturer specifies a PAO-based lubricant 
  • Plain and rolling-element bearings operating at very high or very low temperatures 
  • 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 
  • Electric motor bearings 
  • Industrial worm gear drives with bronze-on-steel gears 
  • Vacuum pumps 
  • Industrial equipment operating over a wide temperature range where an inhibited mineral oil is recommended
