AeroShell W15W-50 Oil

AeroShell W15W-50 Oil is a high-quality, ashless, semi-synthetic multigrade lubricant specifically designed for the demanding requirements of aviation piston engines. It is formulated with a special blend of premium mineral oil and synthetic hydrocarbons, incorporating an advanced additive package specifically developed for multigrade applications.

Advanced Technology for Unrivaled Protection

The unique combination of non-metallic anti-wear additives and high viscosity index base oils (both mineral and synthetic) provides exceptional stability, superior particle dispersion, and outstanding anti-foaming performance. The advanced additive package in AeroShell W15W-50 Oil offers superior protection for engines operating in extreme ambient temperature conditions. Furthermore, the ashless anti-wear additive package provides exceptional wear protection for critical engine components such as camshafts and lifters.

Key Benefits for Engine Health and Efficiency

One of the most significant benefits of AeroShell W15W-50 Oil is its ability to promote engine cleanliness. The ashless polymeric additive has been developed to help eliminate harmful deposits that form in the combustion chamber during normal engine operation. Its multigrade performance allows for improved engine operation across a wide temperature range, facilitating cold weather starting and ensuring rapid lubrication of engine parts.

Additionally, AeroShell W15W-50 Oil can reduce oil consumption in some cases by up to 50% and exhibits excellent resistance to low-temperature thickening, protecting against oil cooler plugging. As an all-season oil, it eliminates the need to change between winter and summer grades depending on ambient temperature.

The high viscosity index semi-synthetic base oils used in AeroShell W15W-50 Oil effectively maintain their viscosity, protecting engine components under the high shear stresses that lubricants are subjected to in an aviation engine. This oil is also compatible with other approved aircraft piston engine oils that meet SAE J-1899 specification and are listed on the corresponding Qualified Products List (QPL). No complicated precautions are necessary when switching from similarly approved aircraft engine oils, provided these oils are qualified products.

Finally, the use of AeroShell W15W-50 Oil can contribute to a fuel consumption reduction of up to 5% compared to straight-grade engine oils.
