Aeroshell Oil W 15W-50 is a unique blend of high quality mineral oil and over 50% synthetic hydrocarbon base stocks, plus the Aeroshell Oil W ashless dispersant additive system. This semi-synthetic blend offers high performance in a wide variety of applications and conditions. The synthetic base stock performance provides for better cold temperature pumping and protection than single grade oils.
In addition, the blend of synthetic and high quality mineral base stocks provide high temperature performance superior to that of other fully approved aircraft piston engine oils. The mineral base stocks help disperse lead by-products of combustion, thereby keeping engines free of “grey paint” or lead sludge that can be a problem with some fully synthetic oils. The anti-wear additive system in Aeroshell Oil W 15W-50 provides outstanding wear protection for critical camshafts, lifters and other high wear components.
The anti-corrosion additive package in Aeroshell Oil W 15W-50 helps protect low usage engines and engines in high humidity climates against rust and corrosion of critical engine parts such as camshafts and lifters. Aeroshell Oil W 15W-50 provides superior anti-corrosion protection for all types of certified aircraft piston engines. When used with proper maintenance procedures, the product provides maximum protection and improves the likelihood that aircraft engines will reach TBO.
In addition, this product provides outstanding high temperature oxidation protection for hot running engines. It is designed to keep engines cleaner with less sludge and varnish build-up in critical ring belt and other areas.
Performance, features & benefits:
– Provides excellent rust and corrosion protection for aircraft engines.
– Promotes engine cleanliness, flights wear, offers excellent anti-foam properties.
– Helps reduce oil consumption by up to 50% and provides superior oil flow at low temperatures.
– Compatible with other approved aircraft piston engine oils.
– Functions as an all season oil, no seasonal changes needed.
– Reduced fuel consumption by up to 5% over single grades.
– Provides superior high temperature oxidation stability.
– Aeroshell Oil W 15W-50 is 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.
Aeroshell Oil W 15W-50 is intended for use in certified four-stroke cycle aircraft piston engines. Aeroshell Oil W 15W-50 is superior to single grade oils in almost every application. It offers easier starting, better lubrication after start-up, reduced wear, reduced corrosion and rusting, and improved cleanliness with oil pressures and temperatures equal to that of single grade SAE 50 oils at fully warmed up conditions. The anti-corrosion additive system is designed to prevent rust or corrosion in all types of aircraft piston engines. In comparative testing of camshaft rusting under high humidity conditions, Aeroshell Oil W 15W-50 was almost entirely rust free while other camshafts conditioned on other oils showed sometimes heavy rusting on cam lobes and bearing surfaces.
