Parts for your 2006 Nissan Serena-Oil filter

2006 Nissan Serena oil filter — what it does and when to replace it

The 2006 Nissan Serena (C25 series) is fitted with a conventional spin‑on engine oil filter. This is documented in the Nissan Serena C25 Service Manual (Lubrication System section) and the Nissan FAST electronic parts catalogue (engine group item 15208 — Oil Filter). Common workshop data sources used across Australia and New Zealand also list a spin‑on filter for the MR20DE petrol engine used in this model year, with similar provisions for diesel variants where fitted.

The oil filter’s job is simple but vital. It strains out grit, combustion by‑products, and microscopic metal particles, keeping the oil clean so the Serena’s bearings, camshafts and timing components live a long and quiet life. A quality filter also manages oil flow with an internal bypass valve (so oil can still circulate if the filter is momentarily overwhelmed) and an anti‑drainback valve to reduce dry starts after the vehicle’s been parked.

• Clean oil protects the engine under Aussie heat and Kiwi hill climbs.
• Anti‑drainback valve helps prevent rattly cold starts.
• Correct bypass pressure ensures the Serena maintains oil pressure under load.

Best practice is to replace the oil filter at every engine oil change. For most 2006 Serenas, that’s about every 10,000–15,000 kilometres or 12 months, whichever comes first. If the van does lots of short trips, stop‑start city work, towing, or drives dusty unsealed roads, tightening that up to 5,000–7,500 kilometres is a smart move. Use engine oil that meets the handbook spec (commonly 5W‑30 to the appropriate API rating) and a reputable filter — genuine Nissan or a known aftermarket brand.

1. Allow the engine to cool, then drain the oil and remove the under‑tray or splash guard if fitted.
2. Spin off the old filter
