2001 Mitsubishi Pajero Oil Filter: Purpose, Fitment and Service Tips

An engine oil filter is absolutely fitted to, and relevant for, the 2001 Mitsubishi Pajero. This is specified in the Mitsubishi NM/NP Pajero workshop manuals (lubrication sections for 6G7 petrol and 4M41 diesel engines), confirmed by the Mitsubishi ASA electronic parts catalogue, and mirrored across major AU/NZ filter catalogues from brands like Ryco, Wesfil/Cooper, and Mann‑Filter. Every factory engine offered in 2001 (including the 3.5L V6 petrol and 3.2L DI‑D diesel) uses a spin‑on engine oil filter mounted to the block.

On this model, the oil filter’s job is to trap fine contaminants—metal particles, combustion by‑products, dust, and sludge—so only clean, well‑pressurised oil circulates through bearings, camshafts, lifters and turbo (on diesel). That keeps wear down, oil passages clear, and temperatures stable, helping the Pajero stay smooth and dependable on long Kiwi and Aussie drives, towing the boat, or tackling corrugated gravel tracks.

For servicing, most owners and mechanics replace the oil filter with every oil change. In typical Australian and New Zealand conditions, that’s usually every 10,000–15,000 km or 6–12 months for petrol, and 7,500–15,000 km or 6–12 months for diesel. If the Pajero tows regularly, idles a lot, or sees dusty outback or farm work, it’s smart to shorten intervals. Always follow the owner’s manual or the factory service manual if they differ.

• Warm the engine first so the oil drains cleanly.
• Check the old filter’s sealing ring isn’t stuck to the housing.
• Lightly oil the new filter’s gasket
