2022 Subaru Impreza Oil Filter — What It Does and When to Change It

Yes, the 2022 Subaru Impreza absolutely uses an oil filter. That’s confirmed by technical sources such as the 2022 Subaru Impreza Owner’s Manual (Engine Oil and Filter section), Subaru Australia/New Zealand Service & Warranty materials, and the Subaru parts catalogue, which lists a spin‑on oil filter for the FB20 2.0‑litre boxer engine (commonly referenced as Subaru part number 15208AA15A or superseding equivalents). So the oil filter is very much relevant to this model.

On this Impreza, the oil filter’s job is straightforward but critical: it traps abrasive particles, combustion by‑products, and sludge so the engine only sees clean, pressurised oil. That keeps the variable valve timing hardware happy, protects the tight clearances in the flat‑four, and helps the engine deliver smooth, efficient performance day in, day out.

For owners in Australia and New Zealand, the sensible approach is to replace the oil filter at every scheduled engine oil change. Subaru’s typical service cadence for the Impreza is around every 12 months or 12,500 km (whichever occurs first), though shorter intervals can be wise if the car does lots of short trips, frequent cold starts, dusty driving, or towing. A fresh filter with the correct 0W‑20 full‑synthetic engine oil maintains proper oil pressure and flow, especially on cold starts where protection matters most.

When fitting a new filter, technicians will lightly oil the gasket, spin it on until the gasket contacts the base, then tighten by hand (usually about three‑quarters of a turn). Over‑tightening can make future removal a headache and risk damaging the seal. With the filter replaced, the FB20 typically takes about 4.5 litres of oil (with filter), but the dipstick is always the final word — top up to the upper mark without overfilling.

Small habits go a long way for this boxer engine’s longevity:

• Use an OEM‑spec filter built for the FB‑series engine and quality oil meeting the latest API/ILSAC specs.
• Stick to time‑based servicing even with low kilometres — oil and filters age with heat and moisture.
• After any oil/filter change, start the engine, check for leaks, and recheck the level after a short drive.

What oil filter does a 2022 Subaru Impreza use?

The 2022 Impreza with the 2.0‑litre FB20 uses a spin‑on filter specified by Subaru for the FB‑series engine. A commonly cited genuine part number is 15208AA15A (with regional supersessions possible). Using an OEM‑spec filter helps maintain correct oil flow and filtration. If uncertain, confirm by VIN with a Subaru dealer or trusted parts supplier.

How often should the oil filter be changed?

Best practice is at every oil service — typically every 12 months or about 12,500 km in AU/NZ. If the vehicle sees severe service (stop‑start commuting, dusty roads, repeated short trips, or towing), changing oil and filter earlier — say every 7,500–10,000 km — is a smart move for engine health.

What oil type and capacity go with a new filter?

Subaru calls for 0W‑20 full‑synthetic that meets the latest API/ILSAC standards. Capacity is about 4.5 litres with a new filter fitted. Fill, run the engine briefly, allow it to settle, and top up to the dipstick’s upper mark. Always avoid overfilling.
