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.
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.
I have used it since Exxon discontinued their Elite aviation oil, and it seems to be working fine.
Really pleased with this oil. My T206H engine is at 2350 hours TT, 900 STOH, is turbocharged and typically flown rich of peak, so the oil is black at 40 hour changes. The turbo causes oil to run hot too, and being a Lycoming, there are small, annoying gasket leaks in the casing and other places. Since changing from Phillips 20W50 with Camguard added, to this Victory oil, for about the last 2 oil changes Ive noticed fewer case leaks and less belly oil, as well as lower oil consumption. So Im a fan of this oil and recommend you try a case. The additive in Victory oil is recommended by Lycoming, and is premixed in the right proportion, so the additive isnt diluted if you add oil. Get some!
Purchased the Victory oil for my 2002 Cessna T182T. I have been using Phillips 66 oil plus Camguard since purchasing 3 years ago . 2150 hours on original engine, oil changed every 30 hours, Blackstone oil analysis shows no abnormal wear. Shooting for 2400 TBO!
Finally Phillips gives us a multi grade oil with the Lycoming additive- good value
The Victory 20W-50 is pre-blended with the proper concentration of antiscuff/antiwear additive (LW-16702). Normal 20W-50 does not have this additive.
The Victory oil can be mixed with the standard X/C. It is basically the same oil but with the LW-16702 additive included.
You can if you would like but the additive in the Victory oil is similar to Camguard.
It is mineral but has ashless dispersant and anti-wear additives. It is not a mineral break in type oil.
