Mobil Rarus™ 800 Series air compressor oils

Mobil Rarus™ 827 and Mobil Rarus™ 829 are high performance oils, primarily intended for the lubrication of severe-duty main and emergency marine reciprocating air compressors. Their balanced formulation provides optimal wear protection and maximized component life.

These lubricants can boost drain intervals up to 2,000 hours compared with 500 hours typical mineral oil alternatives.

Mobil Rarus 800 Series oils offer a range of advantages* including:

  • Outstanding resistance to anti wear and corrosion providing excellent equipment protection and helping enhance equipment life
  • Resistance to oxidation and thermal degradation, helping reduce maintenance downtime and enable long oil life
  • Controlling sludge and deposit formation for improved valve performance and cleaner compressors
  • Broad seal compatibility for many specialized materials
  • Longer running periods between maintenance intervals
