Product Description

Mobil Rarus 827, 5 gallon pail, is a supreme performance air compressor lubricant primarily intended for the lubrication of severe duty reciprocating air compressors but not recommended for air compressors used in breathing air applications. It is engineered to meet or exceed the stringent requirements of the major compressor manufacturers.

Mobil Rarus provides excellent wear protection and outstanding resistance to oxidation and thermal degradation, greatly superior to mineral oils. Its unique formulation provides the ability to help reduce maintenance costs byminimizing equipment problems and downstream deposits and carryover. It also has the following benefits:

High Performance Synthetic Base Stocks:

  • Significant performance capabilities relative to mineral oils
  • Improved safety

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



  • All types of air compressors but specifically recommended for reciprocating air compressor
  • Units operating under severe conditions
  • Multistage units with a history of excessive oil degradation from mineral oil-based products
  • They can be used for cylinder and crankcase lubrication
  • Compressor systems with critical gears and bearings
  • Compressors used in stationary and mobile applications

  1. 5 Star Review Air Compressor Oil

    Posted by on

    I use it for my 5hp compressors that run almost continuously in the winter. There are cheaper air compressor oils that maybe would work, but I'm afraid to use those since my compressors are used so hard. I don't really have much to compare it to.

    Do note that the container is not as shown. It comes in a silver metal can, not a red plastic pail. Not that it matters to me.

    I buy one or two a year.
