AEROSHELL Oil W100 – 12/1 Quart Case
AEROSHELL Oil W100 combines non-metallic additives with select high viscosity index base stocks to give exceptional stability, dispersancy and anti-foaming performance. These additives leave no metallic ash residues that can lead to deposit formation in combustion chambers and on spark plugs, which can cause pre-ignition and possible engine failure. SAE Viscosity Grade 50.

Approved for use in four-stroke (four-cycle) certified aircraft reciprocating piston engines, including fuel-injected and turbocharged engines.
The common choice for most operators of Lycoming and Continental flat engines but, during colder parts of the year, use of AeroShell W80 in place of AeroShell W100 would be an excellent choice.
Most radial engine operators use AeroShell W120 in warm weather with AeroShell W100 or AeroShell W 15W-50 being used in cooler ambient temperatures.
Not recommended for use in automotive engines.
