AeroShell Oil W100 Plus is the only single grade blended with this antiwear 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 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 is not recommended for use in helicopter with a common sump for the engine and transmission. The anti-wear additives makes the oil more slippery than regular single grades. This can cause the transmission to slip. The Product is not recommended for the breaking in of a new engine for the same reason.
