This quart (946 mL) container delivers an oil that exceeds the NMMA FC-W standard and is FC-W Cat compatible, making it suitable for outboard, sterndrive, and inboard engines that call for catalyst-safe lubrication.\u003c\/p\u003e\u003cp\u003eThe 25W-40 viscosity synthetic blend formula is engineered to protect critical engine components across a range of operating temperatures while offering maximum corrosion protection, an important factor for engines that see regular exposure to moisture and marine environments. Because it is approved for all 4-stroke applications, this oil works across outboard, sterndrive, and inboard platforms rather than being limited to a single engine type.\u003c\/p\u003e\u003cp\u003eThis listing is for the single quart size; Sierra also packages this same 25W-40 FC-W Cat synthetic blend oil in 5 quart, 55 gallon, and pallet quantities under related part numbers for buyers who need larger volumes.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-9440CAT-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Quart (946 mL)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Quantity:\u003c\/strong\u003e 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eViscosity:\u003c\/strong\u003e 25W-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Type:\u003c\/strong\u003e Synthetic Blend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e 4-Stroke Outboard, Sterndrive, and Inboard Engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e Exceeds FC-W requirements; FC-W Cat Compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282326029\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury Cross Reference:\u003c\/strong\u003e 92-8M0078629\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eApproved for all 4-stroke applications including outboard, sterndrive, and inboard engines, including engines equipped with emission catalyst systems.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003e92-8M0078629\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat viscosity is Sierra 18-9440CAT-2 oil?\u003c\/strong\u003e Sierra 18-9440CAT-2 is a 25W-40 viscosity synthetic blend engine oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this oil safe for engines with catalytic converters?\u003c\/strong\u003e Yes, Sierra 18-9440CAT-2 is FC-W Cat compatible, meaning it is formulated for 4-stroke engines with emission catalyst systems as well as those without.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size container does 18-9440CAT-2 come in?\u003c\/strong\u003e This part number, 18-9440CAT-2, is packaged as a single quart (946 mL) container, sold 12 to a case.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra 18-9440CAT-2 meet NMMA FC-W standards?\u003c\/strong\u003e It exceeds all 4-stroke requirements including the FC-W standard and is also FC-W Cat compatible.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-9440CAT-2 full synthetic or synthetic blend?\u003c\/strong\u003e Sierra 18-9440CAT-2 is a synthetic blend formula, not a full synthetic oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engine types is this oil designed for?\u003c\/strong\u003e Sierra 18-9440CAT-2 is approved for all 4-stroke applications, including outboard, sterndrive, and inboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a Mercury equivalent to Sierra 18-9440CAT-2?\u003c\/strong\u003e Yes, the Mercury cross-reference number for Sierra 18-9440CAT-2 is 92-8M0078629.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this oil offer corrosion protection?\u003c\/strong\u003e Sierra 18-9440CAT-2 is formulated to offer maximum corrosion protection for 4-stroke marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does one quart of 18-9440CAT-2 weigh?\u003c\/strong\u003e One quart of Sierra 18-9440CAT-2 weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra offer this same oil in larger sizes?\u003c\/strong\u003e Yes, the same 25W-40 FC-W Cat synthetic blend formula sold as 18-9440CAT-2 in quart size is also available in 5 quart, 55 gallon, and pallet-quantity packaging under related Sierra part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for Sierra 18-9440CAT-2?\u003c\/strong\u003e The UPC for Sierra 18-9440CAT-2 quart oil is 808282326029.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988437184731,"sku":"SIE-18-9440CAT-2","price":11.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-9440CAT-2_NEW__45540.1753840728.500.750.jpg?v=1785188078","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-25w-40-synthetic-blend-4-stroke-marine-engine-oil-1-quart-fc-w-catalyst-compatible-replaces-mercury-92-8m0078629-mpn-18-9440cat-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
