Subaru WRX STI Service Schedule Malaysia
The WRX STI service schedule in Malaysia should be more aggressive than standard due to heat and spirited driving. Engine oil every 5,000–7,500 km, spark plugs at 30,000 km, DCCD and differential fluids at 40,000 km, and most critically the timing belt at 100,000 km. Following this schedule is essential for engine longevity.

WRX STI Service Schedule
- Engine oil (5W-30 or 0W-40 full synthetic): every 5,000–7,500 km maximum
- Gear oil (STI 6MT): Subaru Genuine MT Fluid — every 30,000 km
- Brake fluid: every year (track/spirited use) or 2 years
- Spark plugs: every 30,000–40,000 km (heat range for tuned cars may differ)
