The 95402 exceeds the requirements of \u003cstrong\u003eNMMA TC-W3\u003c\/strong\u003e, \u003cstrong\u003eJASO\u003c\/strong\u003e, \u003cstrong\u003eISO\u003c\/strong\u003e, and \u003cstrong\u003eAPI\u003c\/strong\u003e standards, making it compatible with virtually all 2-stroke outboard engines — including modern direct-injection systems. The fully synthetic base provides cleaner combustion, reduced carbon deposits, and superior protection compared to conventional or semi-synthetic alternatives.\u003c\/p\u003e\u003cp\u003eSuitable for both oil injection systems and pre-mix applications, this oil is formulated to minimize ring sticking, exhaust port blockage, and deposit buildup — common failure points in high-output 2-stroke engines. The reduced aquatic toxicity profile makes it a responsible choice for use in sensitive freshwater and coastal environments.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 95402\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Fully synthetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRating:\u003c\/strong\u003e TC-W3 \/ JASO \/ ISO \/ API\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine type:\u003c\/strong\u003e 2-stroke outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Oil injection systems and pre-mix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 1 US quart (~946 mL)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.9 kg (2.0 lb)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e The quart is the right size for topping up an oil injection reservoir, carrying a spare on board for longer passages, or running a pre-mix engine that doesn’t consume a full gallon per season.
