It is designed as a direct fitment for Volvo Penta D4 series diesel engines, including the D4-180i, D4-210, D4-225, D4-260, and D4-300 model families, where it works as the bypass filter alongside the engine's full-flow filter to provide finer, secondary oil filtration and extend engine oil life.\u003c\/p\u003e\u003cp\u003eConstruction is a heavy-wall steel canister that is epoxy coated for corrosion resistance, standing up to the moisture and salt exposure typical of marine engine rooms.

As a 10W-30 multi-viscosity oil, it is designed to flow readily at startup while maintaining a protective film at normal operating temperatures.\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 18-9421CAT-7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Catalyst Semi-Synthetic Oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eViscosity Grade:\u003c\/strong\u003e 10W-30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Type:\u003c\/strong\u003e Semi-Synthetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size:\u003c\/strong\u003e 55 Gallons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282388522\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat viscosity is Sierra 18-9421CAT-7 oil?\u003c\/strong\u003e Sierra 18-9421CAT-7 is a 10W-30 multi-viscosity oil, formulated to flow well at startup and hold its protective film at normal operating temperature.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a synthetic or conventional oil?\u003c\/strong\u003e It is a semi-synthetic blend, combining conventional and synthetic base stocks in the Sierra 18-9421CAT-7 Catalyst oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size container does 18-9421CAT-7 come in?\u003c\/strong\u003e Sierra 18-9421CAT-7 is packaged in a 55 gallon drum, intended for bulk or high-volume use rather than individual quart or gallon purchases.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWho is the 55 gallon drum size intended for?\u003c\/strong\u003e The 55 gallon drum format of Sierra 18-9421CAT-7 is intended for shops, marinas, and service operations that use enough oil to benefit from bulk purchasing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for Sierra 18-9421CAT-7?\u003c\/strong\u003e The UPC for the Sierra 18-9421CAT-7 Catalyst Semi-Synthetic 10W-30 oil is 808282388522.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes semi-synthetic oil perform differently than full synthetic?\u003c\/strong\u003e Semi-synthetic oil, like Sierra 18-9421CAT-7, blends conventional and synthetic base stocks, which typically offers improved performance over conventional oil at a different cost point than full synthetic formulations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan 18-9421CAT-7 be purchased in smaller container sizes?\u003c\/strong\u003e The Sierra 18-9421CAT-7 part number as listed here refers specifically to the 55 gallon drum size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the 10W-30 rating mean for cold starts?\u003c\/strong\u003e The 10W in the 10W-30 rating on Sierra 18-9421CAT-7 indicates the oil's flow characteristics at lower temperatures, helping it circulate more readily during startup compared to a higher first-number oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-9421CAT-7 sold by the individual quart?\u003c\/strong\u003e No, this listing is for the 55 gallon bulk drum of Sierra 18-9421CAT-7 Catalyst Semi-Synthetic 10W-30 oil, not individual quarts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the brand of the Catalyst Semi-Synthetic 10W-30 oil?\u003c\/strong\u003e The Catalyst Semi-Synthetic 10W-30 oil in the 55 gallon drum is manufactured by Sierra under part number 18-9421CAT-7.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988436627675,"sku":"SIE-18-9421CAT-7","price":2092.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sierra_lg_949__26559__16093.1772547083.500.750.jpg?v=1785329143"},{"product_id":"sierra-18-9440cat-4-25w-40-synthetic-blend-catalyst-4-stroke-marine-engine-oil-5-quart-4-7l-outboard-sterndrive-inboard-fc-w-cat-compatible","title":"Sierra 25W-40 Synthetic Blend Catalyst Engine Oil, 5 Quart (18-9440CAT-4)","description":"\u003cp\u003eSierra 25W-40 Synthetic Blend Catalyst Engine Oil is a 5 quart (4.7 L) supply of marine-grade 4-stroke engine oil, part number 18-9440CAT-4.
