AeroShell Oil W100 Plus and W80 Plus – The premium single-grade aviation oils.
Single-grade ashless dispersant engine oils
AeroShell Oils W100 Plus and W80 Plus are new single-grade oils that combine proven AeroShell ashless dispersant technology with advanced anti-wear additives. They’re the oils for pilots who want a single grade that delivers extra protection and performance.
The above oils bring together the best qualities of two of the world's best-selling four-cycle aviation oils. They have the single grade, ashless dispersant performance found in AeroShell Oils W100 and W80 and the anti-wear/anti-corrosion additives of AeroShell Oil W 15W-50 Multigrade.
Their single-grade heritage means outstanding resistance to heat, especially in the summer months. Their ashless dispersant formulation helps reduce deposits of harmful metallic ash in combustion chambers. And their advanced additives work against rust, corrosion, and wear in a way no other single grade does. There are simply no better single-grade aviation oils.
AeroShell W100 Plus and W80 Plus product 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. These engine oils also eliminate 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 meet Lycoming requirements, as well as the US Federal Aviation Authority Airworthiness directive 80-04-03.
- Promotes a clean engine. The non-ash forming, polymeric additive was developed to help 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 help 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.
AeroShell W100 Plus and W80 Plus specifications and approvals
- Lycoming Service Bulletin 446C and 471, plus Service Instruction 1409A.
- MIL-L-22851 (obsolete).
- SAE J1899 – SAE grade 40 (AeroShell Oil W80 Plus) and SAE grade 50 (AeroShell Oil W100 Plus).
- Continental recommended.
- FAA Airworthiness Directive 80-04-03.
AeroShell Oil W100 Plus and W80 Plus are the only single-grade oils blended with this anti-wear additive technology. That means that owners of Lycoming model engines, specified in the applicable service bulletin, don't have to add any supplemental additives to the oil.
AeroShell Oil W100 Plus and W80 Plus can be used in any certified engine. This includes Lycoming, Continental, Pratt & Whitney radial, and most radical, opposed, or in-line engines.
AeroShell Oill W100 Plus and W80 Plus are not recommended for use in helicopters with a common sump for the engine and transmission. The anti-wear additives make the oil more slippery than regular single grades, which can cause the transmission to slip. The product is not recommended for breaking in a new engine for the same reason.
