1998 Nissan Pulsar oil filter — purpose and servicing advice

Based on technical sources, the 1998 Nissan Pulsar (N15 series) absolutely uses an engine oil filter. The Nissan Pulsar N15 Factory Service Manual (Engine Lubrication section) specifies a full‑flow, spin‑on oil filter, and the Owner’s Manual maintenance schedule lists oil and filter changes at regular intervals. Major aftermarket catalogues used in Australia and New Zealand (e.g., Ryco, Sakura, and Wesfil/Cooper) also list dedicated spin‑on oil filters for the 1998 Pulsar’s GA16DE and SR20DE petrol engines. So yes—an oil filter is relevant and fitted to this vehicle.

The oil filter’s job is to trap abrasive particles, sludge, and combustion by‑products that circulate in the engine oil. By keeping the oil clean, it helps the GA16DE or SR20DE maintain proper oil pressure, protect bearings and camshafts, and extend engine life. On this model, the filter is a spin‑on canister that’s easy to replace during routine servicing.

For local conditions, a practical service interval is every 10,000 km or 6 months—whichever comes first—aligning with Nissan’s 1990s maintenance guidance. If the Pulsar does lots of short trips, dusty driving, frequent cold starts, or towing, consider shortening that to 5,000–7,500 km. Always change the filter whenever the oil is changed
