Check every 15,000 miles (24,000 km), replace as needed or every 30,000 miles (48,000 km).

Fuel Filter Replacement:

Typically every 30,000 miles (48,000 km).

Coolant Change Interval:

BMW coolant (G48 or similar) typically recommended every 2-3 years or 30,000-50,000 miles (48,000-80,000 km).

Engine Oil Spec M50 M60:

SAE 5W-30 or 5W-40 full synthetic, meeting BMW Longlife-98 or Longlife-01 specifications (check manual for exact specification matching).
