It is formulated for use in engines equipped with catalytic converters, and Sierra states these oils are designed to meet the unique requirements of modern 4-stroke recreational engines, with or without a catalytic converter. This makes it a suitable choice for boat owners who want a single oil that covers both catalyst-equipped and non-catalyst 4-stroke outboard and sterndrive engines without having to stock two different formulations.\u003c\/p\u003e\u003cp\u003eThe 10W-30 viscosity provides reliable lubrication and protection across a range of operating temperatures typical of recreational marine use. The oil is packaged in a convenient bottle for easy pouring during routine oil changes and top-offs. Sierra also cross-references this product to Mercury part number 92-8M0078625, so it can be used as a direct equivalent where that Mercury oil is specified.\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 18-9420CAT-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury Cross Reference:\u003c\/strong\u003e 92-8M0078625\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eViscosity:\u003c\/strong\u003e 10W-30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Type:\u003c\/strong\u003e Premium blend catalyst engine oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 32 fluid ounces (1 quart \/ 946 ml)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Type:\u003c\/strong\u003e Bottle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282325961\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for 4-stroke recreational marine engines, with or without a catalytic converter.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e92-8M0078625 (Mercury)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size does the 18-9420CAT-2 come in?\u003c\/strong\u003e Sierra 18-9420CAT-2 is packaged as a 1 quart (946 ml) bottle of 10W-30 premium blend catalyst engine oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this oil safe for engines with a catalytic converter?\u003c\/strong\u003e Yes, this 10W-30 premium blend is a catalyst engine oil, formulated to meet the requirements of modern 4-stroke recreational engines with or without a catalytic converter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat viscosity is Sierra 18-9420CAT-2?\u003c\/strong\u003e It is a 10W-30 viscosity engine oil, sold as a premium blend rather than a full synthetic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this oil have a Mercury equivalent number?\u003c\/strong\u003e Mercury part number 92-8M0078625 corresponds to the same quart-size product as Sierra 18-9420CAT-2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this oil be used in engines without a catalytic converter?\u003c\/strong\u003e Yes, the 18-9420CAT-2 formulation is designed to meet the requirements of modern 4-stroke recreational engines whether or not they have a catalytic converter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-9420CAT-2 a full synthetic oil?\u003c\/strong\u003e No, it is labeled as a premium blend catalyst engine oil, not a full synthetic formulation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat container does the oil come in?\u003c\/strong\u003e The 1 quart size of 18-9420CAT-2 is packaged in a bottle.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does a quart of 18-9420CAT-2 weigh?\u003c\/strong\u003e A 1 quart bottle of Sierra 18-9420CAT-2 weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-9420CAT-2 only available in a quart size?\u003c\/strong\u003e The quart (946 ml) bottle is one packaging option for this oil; it is also offered in other case and bulk configurations under related part numbers in the same catalyst oil line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this product?\u003c\/strong\u003e The UPC for the 1 quart Sierra 18-9420CAT-2 catalyst engine oil is 808282325961.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988436988123,"sku":"SIE-18-9420CAT-2","price":9.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-9420CAT-2.png?v=1784938574","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-9420cat-2-10w-30-catalyst-engine-oil-1-quart-mercury-92-8m0078625-for-catalyst-equipped-4-stroke-marine-engines","provider":"Good Vibes Marina","version":"1.0","type":"link"}
