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.
Applications
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.
