Oil Change:
Every 3,000 - 7,500 miles (12 months) or as per severe/normal driving conditions specified in the manual. Consult the manual for exact recommendation based on oil type used.
Air Filter Replacement:
Every 15,000 - 30,000 miles (or annually).
Spark Plug Replacement:
Refer to manual for specific type (e.g., platinum) and interval (often 60,000 - 100,000 miles).
Timing Belt Replacement:
Crucial! Approximately every 60,000 - 90,000 miles or 5-7 years, as this is an interference engine. Manual will detail exact interval and procedure.
