1997 Mitsubishi Pajero Oil Filter — What It Does and When to Replace It

Technical references confirm the 1997 Mitsubishi Pajero absolutely uses an engine oil filter. The Mitsubishi Motors Workshop Manual for second‑generation Pajero (1991–1999) details a full‑flow, spin‑on oil filter in the lubrication system across common engines of the era (including 4M40 2.8 TD, 4D56 2.5 D, 6G72 3.0 V6 and 6G74 3.5 V6). Mitsubishi’s ASA/EPIC parts catalogues list the oil filter assembly under engine lubrication, and major AU/NZ filter catalogues (e.g., Ryco, Sakura, WIX) specify direct‑fit spin‑on filters for the 1997 Pajero. So yes—this vehicle is designed to run with an oil filter, and it’s a key service item.

The oil filter on a 1997 Pajero works quietly in the background, trapping grit, carbon, metal flecks and sludge that would otherwise chew through bearings, cam lobes and turbochargers (on diesel models). It’s a full‑flow design, meaning all engine oil is routed through the filter media before it heads back to lubricate crucial components. A quality filter helps maintain stable oil pressure, reduces engine wear on cold starts via an anti‑drainback valve, and includes a bypass valve so the engine still gets oil if the element ever becomes overly restricted.

As part of regular servicing, replacing the oil and filter on time is one of the smartest moves for long engine life. For most AU/NZ conditions, a sensible interval is every 10,000 km or 6 months for petrol models, and 5,000–10,000 km (or 6 months) for diesels—shorter if you tow, work in dusty conditions, do lots of short trips, or idle for long periods. Many workshops simply fit a fresh filter at every oil change
