Engine Oil Change:
Every 3,000 to 7,500 miles (5,000 to 12,000 km) or 6-12 months, depending on oil type and driving conditions. Consult manual for specifics.
Transmission Fluid Change:
Every 30,000 to 60,000 miles (48,000 to 96,000 km), depending on usage. High-stress driving may require more frequent changes.
Coolant Flush:
Every 30,000 to 100,000 miles (48,000 to 160,000 km) or 2-5 years, depending on coolant type. Consult manual for OAT vs. HOAT.
