1998 Mitsubishi Pajero engine-oil: what it does and how to look after it

Engine oil is absolutely relevant to a 1998 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero Owner’s Manual and Workshop Manual for this model year, plus industry standards like SAE J300 (viscosity grades) and API/ACEA service classifications, all specify engine oil requirements for the Pajero’s petrol and diesel engines. It’s a core service fluid, not an optional extra.

For this generation Pajero, engine oil does a stack of heavy lifting: it lubricates moving parts to cut wear, carries heat away from hot spots, suspends soot and contaminants for the filter to catch, protects against rust and corrosion, and helps seal the piston rings for better compression. That’s why fresh, correctly graded oil keeps the 6G7x V6 or 4M40 diesel running sweet, whether it’s the daily commute or a long haul towing the boat.

Service guidance from Mitsubishi for late‑1990s Pajero models commonly calls for oil and filter changes about every 10,000 km or 6 months under normal Australian and New Zealand driving, and more often (around 5,000–7,500 km) if it’s doing dusty tracks, frequent towing, or lots of short trips. Always match the oil spec to the engine and climate: petrol variants typically suit quality API SJ (or later) 5W‑30, 10W‑30 or 10W‑40 depending on ambient temperatures
