If you're ordering for an older engine and your service manual lists one of those earlier numbers, 21549542 is the current OEM replacement. Always confirm with your engine serial number if you're unsure, as filter fitment can vary across production runs within the same engine family.\u003c\/p\u003e\n\n\u003ch3\u003eService Interval\u003c\/h3\u003e\n\u003cp\u003eReplace this oil filter at every engine oil change. Volvo Penta typically recommends oil and filter changes every 250 hours or annually, whichever comes first — refer to your engine's service manual for the exact interval for your model and serial number range. Replace sooner if oil analysis or inspection indicates contamination.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this a full-flow or bypass filter?\u003c\/strong\u003e\u003cbr\u003eA: This is a bypass oil filter. It works alongside the full-flow filter to provide additional fine filtration, removing smaller particles that pass through the primary filter. Both filters should be replaced at each oil service.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does 21549542 replace 3827069 and 829390?\u003c\/strong\u003e\u003cbr\u003eA: Yes — 21549542 is the current OEM part number that supersedes both 3827069 and 829390. It is the correct replacement for those earlier references.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I know if my engine uses a bypass filter?\u003c\/strong\u003e\u003cbr\u003eA: D, TAMD, and MD series Volvo Penta diesels typically use both a full-flow and a bypass filter. Check your engine's service manual or parts diagram to confirm the filter locations and part numbers for your specific model.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-oil-filter-21707132-oem-marine-engine-oil-filter\"\u003eVolvo Penta Oil Filter 21707132\u003c\/a\u003e — OEM oil filter for D4\/D6 engines\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-oil-filter-847741\"\u003eVolvo Penta Oil Filter 847741\u003c\/a\u003e — related OEM oil filter\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-gearbox-oil-filter-3582069-hs25a-hs80ive-hs85ive-oem\"\u003eVolvo Penta Gearbox Oil Filter 3582069\u003c\/a\u003e — transmission oil filter, replace at same service\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-synthetic-engine-oil-10w-40-5-gallon-oem-21681796\"\u003eVolvo Penta Synthetic Engine Oil 10W-40\u003c\/a\u003e — OEM engine oil for oil change service\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-fuel-filter-21718912-oem-d4-d6-diesel-water-separating-filter\"\u003eVolvo Penta Fuel Filter 21718912\u003c\/a\u003e — replace fuel filter at same service interval\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563988353060,"sku":"21549542","price":33.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/773e045f-d6be-468c-8ef4-53b308f0cf97.png?v=1773088226","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-oil-filter-21549542","provider":"Marisol Marine Company","version":"1.0","type":"link"}
