1998 Daihatsu Terios Oil Filter — What It Does and How to Look After It

Based on technical references including the Daihatsu Terios J100-series workshop manual (1997–2005), the Toyota/Daihatsu electronic parts catalogue, and AU/NZ aftermarket filter catalogues, the 1998 Daihatsu Terios is fitted with a full-flow, spin-on engine oil filter. It’s a standard service item and absolutely relevant to the vehicle’s reliability.

The oil filter’s job is simple but crucial: it traps fine metal particles, combustion by-products, and sludge so the engine oil can keep bearings, camshafts and rings nicely lubricated. On the Terios’s 1.3-litre petrol engine, the filter is designed to flow all engine oil through its media, with an internal bypass valve to protect oil flow if the filter ever gets too clogged. A healthy filter means cleaner oil, easier cold starts, and less wear over time – exactly what you want from a compact 4x4 that sees a mix of city runs and weekend tracks.

Best practice in Australia and New Zealand is to replace the oil filter at every oil change. For an older car like a ’98 Terios, that’s typically every 10,000 km or 6 months, whichever comes first. If it’s doing lots of short trips, dusty road work, or towing, bring that interval forward to roughly 5,000–7,500 km. Always use a quality filter that meets OEM specifications and pair it with the correct oil grade recommended in the owner’s handbook for local climate.

When servicing, warm the engine slightly, drain the oil, then remove the old filter. Make sure the old rubber gasket isn’t left behind on the block. Lightly oil the new filter’s gasket, spin it on until the seal touches, then hand-tighten a further three-quarters to one turn. Refill with the right amount of oil, start the engine, and check for leaks. Dispose of used oil and the old filter responsibly at a recycling facility.

Quick tips owners appreciate:

• Choose reputable AU/NZ brands that list the Terios by year/engine.
• If the filter mounts vertically, pre-fill it to reduce dry-start time.
• Keep an eye on oil colour and level between services, darkening is normal, but rapid darkening or rising level can hint at other issues.

Keeping the oil and filter fresh is cheap insurance that helps a 1998 Terios stay smooth and dependable for years.

Popular questions about 1998 Daihatsu Terios oil filters

What kind of oil filter does a 1998 Daihatsu Terios use?
It uses a spin-on, full-flow engine oil filter. Match by vehicle details (year, engine code, and VIN if needed) using trusted AU/NZ parts catalogues to ensure correct thread, gasket diameter, and bypass/anti-drainback features.

How often should the oil filter be changed?
Replace it at every oil change — generally every 10,000 km or 6 months for typical use, and sooner if the vehicle sees dusty roads, frequent short trips, or towing. Pairing a new filter with fresh oil maintains proper lubrication and protects against premature engine wear.

Where is the oil filter located?
It’s mounted on the engine block and is usually accessed from underneath on the first‑gen Terios. Depending on skid plates or accessories, a socket-style filter tool can make removal easier. Always confirm location and orientation before loosening.
