Single grade heritage means outstanding resistance to heat, especially in the summer months. Ashless dispersant formultation helps reduce deposits of harmful metallic ash in combustion chambers.

AeroShell Oil W 100 Plus and W 80 Plus are the only single grade oils blended with this antiwear additive technology, which means that owners of Lycoming model engines specified in the applicable service bulletin don't ahve to add any supplemental additives to the oil.


AeroShell Oil W 100 Plus can be used in any certified engine, including Lycoming, Continental, Pratt & Whitney radial and most radical, opposed or in-line engines. It is not recommeneded for use in helicopter 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. This product is not recommended for the breaking in of a new engine for the same reason.

This product can only be shipped via LTL carriers, freight methods will be restricted.
