2025 Subaru WRX oil — questions before buying
- Can I use 5W-20 or 5W-30 instead of 0W-20 in my 2025 Subaru WRX?
- The checked source rows on this page list 0W-20 for the 2025 Subaru WRX. Use 0W-20 unless your owner's manual, oil cap, or service information for your exact engine allows another grade. If a retailer suggests 5W-20 or 5W-30, match the engine row first and confirm the grade before buying.
- Did the Subaru WRX change its recommended oil viscosity across model years?
- Yes. Checked records show the Subaru WRX has specified more than one viscosity grade across model years. 2014–2021: 5W-30; 2022–2025: 0W-20. Confirm the viscosity shown on this page matches your exact year before buying oil.
