1998 Nissan Primera Oil Pump — what it does and how to look after it

Yes, the 1998 Nissan Primera (P11) absolutely uses an engine oil pump. Technical sources including the Nissan Primera P11 Factory Service Manual (Lubrication System section), the Haynes Nissan Primera 1990–1999 service manual, and Nissan’s Electronic Parts Catalogue (EPC) all specify an internal, crankshaft-driven trochoid oil pump fitted across the common P11 engines (GA16DE, SR18DE, SR20DE, and CD20 diesel). It’s integrated into the front cover and is essential to the lubrication circuit.

The oil pump’s whole job is to pick up oil from the sump and push it through galleries to bearings, camshafts, lifters, and the timing chain tensioner. On a Primera, consistent oil pressure keeps the top end quiet, the bottom end safe, and the timing chain happy. When the pump is healthy and the oil’s fresh, the engine will run smoother and last a lot longer — easy win for anyone who wants their P11 to keep clocking up the kilometres.

Day to day, the best “maintenance” for the oil pump is simply regular oil and filter changes with the right spec oil for local climate — typically a quality 5W-30 or 10W-40 for petrol variants in Australia and New Zealand, and the correct diesel-rated oil for CD20 models.
