Sierra TC-W3 is a full synthetic oil for 2 stroke outboard engines. This high performance lubricant meets all manufacturer warranties, exceeding JASO, ISO, API, and NMMA standards for advanced 2 cycle marine engine oils. Ideal for both pre-mix and oil injection systems, TC-W3 runs cleaner for smoke-free combustion and significantly lower toxicity to marine life.
Clean running outboards experience far less piston ring sticking and deposit buildup. This reduces friction and allows easier starting. Less friction reduces wear for higher performance and longer engine life.
Engineered for the demands of modern high output outboards, Sierra 2 stroke oil is compatible with lower quality (ie blended) fuels. It's also suitable for personal watercraft and power equipment.
