This multi-grade engine oil is designed for aircraft piston engines, offering year-round performance. Its ashless dispersant formulation reduces engine sludge and deposits, while enhancing starting, oil circulation, and reducing warm-up time. The oil maintains film strength under high loads and temperatures, providing effective protection against wear and scuffing.This multi-gr
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 anti-scuff/anti-wear 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.
