W100 and the anti-wear/anti-corrosion additives of AeroShell Oil W15W-50 Multigrade. They are the oils for pilots who prefer a single grade but who also want the extra protection and performance from the additive package.
The advanced additives in AeroShell Oils W80 Plus and W100 Plus provide better rust and wear protection than conventional single grades. The additives work as a protective barrier to prevent critical parts from being slowly degraded by rust or wear, especially when an aircraft sits idle. This protection helps keep the camshaft and lifters coated, reducing the likelihood of premature damage and helping operators reach TBO.
