Phillips 66 Victory AW 20w-50 Aviation Engine Oil Containing Lycoming Additive LW-16702

Phillips 66 Victory AW 20W-50 Oil is an ashless dispersant, multi-grade engine oil specially formulated for year-round use in aircraft piston engines. Victory AW 20W-50 is pre-blended with the proper concentration of antiscuff/antiwear additive (LW-16702) mandated by Lycoming Service Bulletins 446E and 471B and Service Instruction 1409C. 

It provides distinct performance benefits compared with single-grade engine oils, including easier starting and faster oil circulation at low temperatures, reduced warm-up time, and reduced oil consumption in most engines. It maintains its film strength under high loads and at high temperatures to protect against wear and piston scuffing. 

The ashless dispersant formulation helps minimize the formation of engine sludge, varnish, piston deposits and combustion chamber deposits, resulting in a much cleaner engine compared with the use of straight (non-dispersant) mineral oils. 

Phillips 66 Victory AW 20W-50 Aviation Oil is recommended for use in opposed piston engines. It can replace Commercial Grade 65, 80 or 100 single-grade engine oils with no sacrifice in performance. 

Meets the requirements of:

  • Avco Lycoming Service Instruction 1014
  • Pratt & Whitney Service Bulletin No. 1183 Rev. U
  • SAE Standard J1899
  • Teledyne Continental Material Specification MHS-24B
  • U.S. Military Specification MIL-L-28851D (obsolete) for additive treatment

Features & Benefits:

  • Ashless dispersant helps to minimize engine sludge and varnish deposits, resulting in a cleaner engine
  • Pre-blended with Lycoming-approved anti-wear additive
  • Easier starting and faster oil circulation at low temperatures compared with single-grade oils

  • Protects against rust and corrosion
  • Reduces oil consumption
  • Suitable for use year-round

    Excellent aviation oil - keeps my Lycoming IO-360 in the Mooney M20J humming along nicely year after year! It's got all the additives required to ensure water and acid corrosion does not become an issue as well as enhanced wear protection. I won't buy anything else for my engine.
