Mobil Rarus 427 Mineral Base ISO VG 100 Compressor Oil

Mobil Rarus 427 is a premium performance, ISO VG 100, SAE 30 weight ashless air compressor lubricant designed to meet the stringent requirements of the major compressor manufacturers. This air compressor oil is formulated with high quality mineral base-oils and a high performance additive system designed to provide exceptional equipment protection and reliability for compressors operating under mild to severe conditions.

This oil provides excellent wear protection and the ability to reduce maintenance costs through minimizing equipment problems and downstream deposits and carryover. Based on its high FZG Ratings, it is an outstanding lubricant for compressor systems employing gears and bearings making them an excellent selection for crankcases as well as cylinder lubricants. It also has the following benefits:

Low Ash and Carbon Formation:

  • Improved valve performance
  • Reduced deposits in discharge lines
  • Reduced potential for fires and explosions in discharge systems
  • Improved compressor performance

Outstanding Oxidation and Thermal Stability:

  • Longer oil life
  • Improved filter life
  • Lower maintenance costs

High Load-carrying ability:

  • Reduced wear of rings, cylinders, bearings and gears

Excellent Water Separability:

  • Less carryover to downstream equipment
  • Reduced sludge formation in crankcases and discharge lines
  • Reduced blockage of coalescers
  • Less potential for emulsion formation

Effective Rust and Corrosion Protection:

  • Improved protection of valves and reduced wear of rings and cylinders


  • Reciprocating air compressor crankcases and cylinders
  • Rotary screw compressors
  • Rotary vane compressors
  • Axial and centrifugal compressors
  • Compressor systems with critical gears and bearings
  • Compressors used in stationary and mobile applications
