Parts for your 2016 Subaru Impreza-Engine oil

2016 Subaru Impreza engine oil — what it does and when to change it

Engine oil is absolutely used and essential in the 2016 Subaru Impreza. Technical sources including the Subaru Owner’s Manual for MY16 Impreza and Subaru Australia/New Zealand maintenance schedules specify engine oil for the 2.0‑litre FB-series boxer petrol engine, typically a full synthetic 0W‑20 meeting API SN (or later) and ILSAC GF‑5/6. The viscosity grades referenced follow SAE J300 standards. These sources confirm engine oil is relevant and required for this model.

In this Impreza, quality engine oil does the heavy lifting: it lubricates moving parts to cut friction and wear, carries away heat from hot spots, helps keep internals clean by suspending contaminants, protects against corrosion, and aids sealing around the piston rings. It also supports correct operation of hardware like variable valve timing. Without the right oil at the right level, the flat‑four won’t stay happy for long.

For Australia and New Zealand, Subaru specifies a low‑viscosity full synthetic oil (0W‑20) for everyday use
