2021 Subaru Impreza
30,000 mile service checklist
Here's exactly what your factory maintenance schedule calls for at this mileage — and what each item typically costs.
30,000 mile service
- Engine oil and filter change (0W-20 full synthetic)
- Tire rotation
- Replace engine air filter
- Replace cabin air filter
- Inspect spark plugs — NGK iridium; Subaru factory interval is approximately 60,000 mi, do not replace at 30k
- CVT fluid change recommended under severe-duty conditions; inspect-only under normal use (manual-transmission cars: inspect/replace gear oil per severe-duty schedule)
- Replace rear differential gear oil — typically 75W-90
- Inspect brake fluid — replace if moisture-contaminated
- Inspect coolant condition — Subaru Super Coolant (long-life)
- Inspect timing chain tensioner (FB-series engines use a timing chain, not a belt)
