Mobil Aero HFA Aviation Hydraulic Fluid

Mobil Aero HFA is formulated for aircraft systems where use of hydrocarbon-based hydraulic fluids is required. This product is a low viscosity, high VI (viscosity index) fluid with excellent low temperature properties, good anti-wear performance, and good chemical stability. This fluid is composed of mineral base oil stock and contains shear-stable VI improvers. It also has the following benefits: 

High Viscosity Index (VI): 

  • Allows equipment operation over a wide range of temperatures 

Excellent low temperature properties: 

  • Provides high performance operation in low ambient conditions 

Good chemical and oxidation stability: 

  • Resists the formation of acidic constituents, varnishes, and deposits 

Meets super clean requirements of U.S. Spec. MIL-PRF-5606: 

  • Ensures reliable performance of pumps, servo-valves and other hydraulic system components 


Mobil Aero HFA is a premium quality fluid that meets the quality requirements of the U.S. Military specification MIL-H-5606A (now obsolete). It has a very high VI and is suitable for use at temperatures down to -54 C (-65 F). While this quality fluid is no longer used by the U.S. Military, it is still used in older, small private, and commercial aircraft. It is also used in industrial and commercial equipment requiring good fluidity at very low temperatures and situations requiring trouble-free service over a wide range of operating conditions.
