Parts Desk Insights
Best Use Case: This filter is the correct replacement for scheduled oil service on D, TAMD, and MD series Volvo Penta diesel engines. It's one of the most straightforward maintenance items on these engines — replacing it at every oil change is the single best thing you can do to extend engine life on a high-hour diesel.
Common Issues: The most common question we get is whether 21549542 replaces the older 3827069 or 829390 — yes, it does. 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.
Service Interval
Replace 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.
Technical FAQ
Q: Is this a full-flow or bypass filter?
A: 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.
Q: Does 21549542 replace 3827069 and 829390?
A: Yes — 21549542 is the current OEM part number that supersedes both 3827069 and 829390. It is the correct replacement for those earlier references.
Q: How do I know if my engine uses a bypass filter?
A: 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.
