Oil Change Interval:
Typically every 3,000-5,000 miles (4,800-8,000 km) or 6 months, whichever comes first. Consult manual for exact interval based on driving conditions.
Air Filter Replacement:
Every 15,000-30,000 miles (24,000-48,000 km) or as needed based on operating environment.
Spark Plug Replacement:
Typically every 30,000-60,000 miles (48,000-96,000 km), depending on spark plug type (copper vs. platinum). Refer to manual for specific recommendations and plug part numbers.
Timing Belt Replacement:
Crucial for EJ series engines, which are 'interference' engines. Recommended interval is usually 60,000-100,000 miles (96,000-160,000 km) or 5-7 years. Failure can cause severe engine damage. The manual will provide the exact interval and component part numbers for the kit.
