1996 Mitsubishi Pajero engine oil — what it does and how to look after it

Engine oil is absolutely relevant and required on the 1996 Mitsubishi Pajero. Factory literature such as the Mitsubishi Motors Pajero Owner’s Manual (1996 model year) and the Mitsubishi Workshop Manual for the 4M40 diesel and 6G72/6G74 V6 petrol engines specify engine oil as essential for lubrication and cooling, with API grades appropriate to each engine (API SG/SJ for petrol, API CF-4 or higher for the 2.8L 4M40 turbo-diesel). Viscosity recommendations vary by climate, typically 10W-30 or 10W-40 for most Australian and New Zealand conditions, with 15W-40 suited to hotter regions.

For this generation Pajero, engine oil does the heavy lifting: it forms a protective film between moving parts, carries heat away from bearings and pistons, keeps internals clean by suspending soot and deposits, protects against corrosion, and helps hydraulic lifters operate quietly. Fresh, correctly graded oil keeps the V6s smooth and the 4M40 diesel happy, especially under towing, off-road, or dusty outback use.

Service-wise, owners should plan regular oil and filter changes. Period guidance from Mitsubishi service schedules of the era indicates roughly every 10,000–15,000 kilometres or 6–12 months for normal driving, and a shorter 5,000–7,500 kilometres for dusty routes, lots of idling, or frequent towing. Always replace the oil filter with each change and fit a new sump plug washer to avoid weeping leaks. Typical refill volumes can vary by engine: the V6 petrols generally take around five litres, while the 2.8 turbo-diesel often needs more
