Oil Change Interval:
Every 3,750 miles (6,000 km) or 3 months (severe conditions), 7,500 miles (12,000 km) or 6 months (normal conditions) - consult manual for exact specification.
Timing Belt Replacement:
Every 90,000 - 105,000 miles (144,000 - 168,000 km) or 7-8 years. Critical due to interference engine design.
Spark Plug Replacement:
Typically around 60,000 - 100,000 miles, depending on plug type (platinum/iridium).
Engine Oil Spec:
API SG or SH, SAE 5W-30 or 10W-30 (consult owner's manual for exact viscosity based on temperature).
Coolant Spec:

Transmission Fluid Auto:
Subaru ATF-HP (or Dexron III/Mercon equivalent) - check manual for specific type.
Transmission Fluid Manual:
GL-5 75W-90 Gear Oil
Differential Fluid:
GL-5 75W-90 Gear Oil
Head Gaskets:
While less prevalent than on some EJ series engines, early models can still experience head gasket failures. The manual will detail inspection and replacement procedures.
Timing Belt Wear:
Regular inspection and timely replacement are critical to prevent catastrophic engine damage (interference engine).
Catalytic Converter:
Can become clogged over time, affecting performance and emissions. Manual will cover diagnostic steps.
Automatic Transmission Service:
Regular fluid changes are recommended for the 4EAT to ensure longevity.
