AeroShell W Oils were the first non-ash dispersant oils to be used in
aircraft piston engines. They combine non-metallic additives with selected
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.
AeroShell W120 Oil APPLICATIONS:
AeroShell W Oils are available in four different viscosity grades:
AeroShell Oil W65 – AeroShell Oil W80
AeroShell Oil W100 – AeroShell Oil W120.
The suffix for each grade corresponds to the viscosity of the oil at 210°F in
Saybolt Universal Seconds.
AeroShell W Oils are intended for use in four-stroke cycle certified
reciprocating piston engines, including fuel-injected and turbocharged
engines. AeroShell W Oils are not recommended for use in automotive
engines. For automotive engines converted for use in aircraft, the specific
engine manufacturer or the conversion agency should be consulted for
proper oil recommendation.
Most radial engine operators use AeroShell Oil W120 in warm weather
operations with AeroShell Oil W100 or AeroShell Oil W 15W-50 being
used in cooler ambient temperatures.
AeroShell Oil W100 or AeroShell Oil W 15W-50 are the common choices
for most operators of Lycoming and Continental flat engines but, during
colder parts of the year, use of AeroShell Oil W80 in place of AeroShell
Oil W100 would be an excellent choice.
Although some engine manufacturers and overhaulers suggest in their
service bulletins the use of a straight mineral oil in new or recently
overhauled engines for break-in, other rebuilders and manufacturers
especially for engines such as the Lycoming O-320H recommend use of an
AeroShell W Oil for break-in. Operators should therefore check with
engine rebuilders or manufacturers for the correct recommendations for the
specific engine.
