Oil Change Interval:
Typically every 5,000-7,500 miles (8,000-12,000 km) or annually, as specified in the manual.
Timing Belt Replacement:
Crucial interval, typically every 30,000-50,000 miles (48,000-80,000 km) or 3-5 years. Failure leads to catastrophic engine damage.
Engine Oil:
API SG or higher, SAE 0W-40, 5W-40, or 10W-40. Specific Porsche approval grades may be recommended (e.g., A40).
