Aeroshell W80 Plus offers superior rust and corrosion protection to engine parts that may be susceptible to extreme rusting when an aircraft is not in use. W80 Plus brings together the best qualities of two of the world's best-selling four cycle aviation oils and has the single grade, ashless dispersant performance found in AeroShell W80 and the anti-wear/anti-corrosion additives of AeroShell Oil 15W50 Multigrade. This single grade heritage means outstanding resistance to heat, especially in the summer months and the ashless dispersant formulation reduces deposits of harmful metallic ash in combustion chambers. While the advanced additives work against rust, corrosion and wear in a way no other single grade does.

Aeroshell W80 Plus Benefits:

• Superior Rust and corrosion protection giving that extra protection to engine parts that may be susceptible to extreme rusting when an aircraft is not in use (for prolonged periods of non-use please use AeroShell Fluid 2F).
• Improved anti-wear characteristics particularly at engine start-up and eliminates the need for supplemental additives required by certain Lycoming engines. AeroShell Oil W100 Plus and W80 Plus already contain the Lycoming additive LW 16702 in the correct proportions and meets Lycoming requirements as well as the US Federal Aviation Authority Airworthiness directive 80-04-03.
• Promotes Engine Cleanness. The non-ash forming, polymeric additive was developed to eliminate the harmful combustion chamber and spark plug deposits that form during normal operation.
• High Viscosity Index Base Oils used in AeroShell W oils maintain their viscosity and protect engine components more effectively under the high shear stresses that an engine places on lubricants.
• Provides Compatibility with other approved aircraft piston engine oils. Mixing with other products, however will result in some loss of the superior performance features of AeroShell Oil W100 Plus and W80 Plus.
