Sierra Full Synthetic TC-W3 2-Stroke Outboard Oil, 1 Gallon, BRP E-Tec XD-100 Equivalent (OE 764357) - 18-9540-3

Sierra 18-9540-3 is a full synthetic TC-W3 rated 2-stroke outboard oil packaged in a 1 gallon (3.78L) container. It is formulated for BRP E-Tec and Universal E-TEC XD-100 applications, and is suitable for both oil injection systems and pre-mix applications. The full synthetic formulation is engineered to improve performance and extend engine life by reducing wear on critical engine components under the high loads and harsh conditions of marine use.

The oil is formulated to reduce ring sticking, deposit formation, and exhaust port blockage, which helps keep a 2-stroke outboard running cleanly over time. It also carries significantly reduced aquatic toxicity to fish compared to other outboard oils on the market, an important consideration given the on-water environment these engines operate in. Sierra 18-9540-3 is also available in a quart (964ml) size and a 55 gallon drum for larger volume needs.
