AeroShell Oil W 15W-50 MIL-L-22851
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.
