Sierra 95517 10W-40 FC-W Synthetic Blend Marine Engine Oil – 55 Gal. Drum
A bulk-format 55-gallon drum of Sierra’s 10W-40 synthetic blend marine engine oil, meeting both NMMA FC-W and API SL certifications. Formulated for 4-cycle outboard and inboard engines operating without a catalytic converter, this oil delivers a stable viscosity film across a wide temperature range while providing elevated rust and corrosion inhibitors suited to saltwater and freshwater marine environments. The synthetic blend base also offers strong shear stability and high-load bearing protection under sustained engine use.
The 55-gallon drum format is designed for high-volume service operations — marinas, dealerships, and fleet maintenance programs — where bulk dispensing reduces per-litre cost and eliminates the handling of individual containers.

Parts Desk Insights
Best use case: The 55-gallon drum is the right choice for marinas, service shops, and fleet operators running multiple 4-stroke outboards or inboards on 10W-40 and wanting to reduce per-unit cost through bulk purchasing. It requires a drum pump or dispensing system for practical use — confirm your facility has the appropriate equipment before ordering. For smaller-volume needs, the same 10W-40 FC-W formulation is available in the Sierra 95513 10W-40 FC-W Oil – Gallon and the Sierra 95512 10W-40 FC-W Oil – Quart. Not intended for 2-stroke engines or engines equipped with catalytic converters.
