Phillips 66 - Victory Aviation Oil, 100AW


  • Ashless dispersant helps minimize engine sludge and varnish deposits
  • for a cleaner engine • Pre-blended with Lycoming-approved antiwear additive
  • High film strength for protection against wear and piston scuffing
  • High viscosity index and low pour point for use over a wide temperature range
  • Protects against rust and corrosion
  • Formulated with the same high-quality base oils as used in Phillips 66 X/C® Aviation Oil

Phillips 66® Victory Aviation Oil 100AW is an ashless dispersant, single-grade engine oil 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 is recommended for use in opposed piston and radial piston aircraft engines where cam lifter wear is a concern. 

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. This oil has a high viscosity index and low pour point compared with many other single-grade aircraft engine oils, allowing its use over a wide temperature range.

Victory Aviation Oil 100AW is FAA approved as an alternate method of compliance to AD80-04-03 R2, paragraph b.1.
