NAVOIL: Corrosion-Inhibiting General Purpose Lubricant

The US Navy seeks a partner to license and commercialize a high performance general purpose lubricant with the ability to inhibit corrosion

The US Navy has developed the NAVOIL lubricant to provide 2-4x greater corrosion protection than current products without sacrificing other performance characteristics, even at high and low temperatures.
The Technology: 

The US Naval Air Warfare Center Aircraft Division (NAWCAD) has developed and tested NAVOIL, a patent-pending lubricating oil that exceeds MIL-PRF-32033 requirements and imparts 2-4x greater corrosion protection in salt spray testing than current products. NAVOIL maintains high performance at both low and high temperatures and offers a higher flash point than many competing products without sacrificing lubricity. NAVOIL is a general purpose, water-displacing lubricating oil formulated from commercially available feedstocks.

NAVOIL can be used in diverse applications including aircraft, small arms, and wherever CPCs are used. NAWCAD has funding and is pursuing field testing of the product and revision of the mil-spec to benefit greater corrosion protection.  The US Army has just published Solicitation W56HZV- PRESERVATIVE-OILS, which requests information on products that meet new corrosion protection targets, notably the salt spray test, while still meeting performance specs.


  • High Performance: NAVOIL remains effective even at low temperatures and is comparable to or exceeds the performance of other approved lubricants while providing the additional benefit of exceptional corrosion resistance
  • Military Grade: Exceeds standards established by MIL-PRF-32033
  • Reduced Maintenance Costs: NAVOIL offers 2-4x greater corrosion protection than currently approved products, resulting in greater hardware availability and uptime, and reduced life cycle costs
The Opportunity: 
  • A pending US patent application is available for license
  • Potential for collaboration with Naval Air Warfare Center Aircraft Division researchers
