🔧 Maintenance

Engine Oil Change:

Every 7,500 - 10,000 miles or 12 months, whichever comes first (check specific engine type and oil specification).

Air Filter Replacement:

Every 15,000 - 20,000 miles or 24 months.

Fuel Filter Replacement Petrol:

Every 30,000 - 40,000 miles.

Fuel Filter Replacement Diesel:

Every 20,000 - 30,000 miles (critical for diesel health).

Spark Plug Replacement Petrol:

Every 30,000 - 60,000 miles (depending on plug type, e.g., platinum).

Timing Belt Replacement:

Crucial! Every 40,000 - 60,000 miles or 5 years for most petrol engines (e.g., V6) and some diesel engines. Consult manual for exact interval and engine variant.

Engine Oil Specification:

API SG or SH, ACEA A2-96 or B2-96. Viscosity: 10W-40 or 5W-40 (check specific engine and climate). e.g., Total Quartz 7000/9000.
