Aeroshell Fluid 4 Aviation Hydraulic Oil Meeting MIL-H-5606A Specifications

(Aeroshell Fluid 4 is discontinued and is replaced by Aeroshell Fluid 41)

AeroShell Fluid 4 is a mineral-based hydraulic oil with low temperature characteristics that is capable of operating over a wide range of temperatures. 

This fluid is oxidation inhibited and contains a special anti-wear additive. It is dyed red for identification and leak detection purposes. 


  • Superior low temperature properties 
  • Compatibility with synthetic rubber components
  • Dyed red for easy identification 
  • Good anti-wear properties 


  • Aircraft applications where a MIL-L-5606A fluid is specified or recommended 
  • Hydraulic oil systems, particularly those that are subject to a wide variation in ambient operating temperatures 
  • Winter service for bucket trucks and other portable equipment subject to severe low temperature operation 
  • Should not be used in aviation applications that call for a MIL-H-5606G type fluid 


  • MIL-H-5606A* (obsolete) 
  • DEF STAN 91-048 Grade Normal* 

* AeroShell grade meets the requirements of the listed specification but is not necessarily fully approved to that specification.
