Oil Change Interval Petrol:
Typically every 20,000 km or 1 year, whichever comes first.
Oil Change Interval Diesel:
Typically every 30,000 km or 1 year, whichever comes first (check manual for specific JTDm intervals).
Timing Belt Replacement:
For petrol engines with timing belts (e.g., 2.2 JTS), usually around 100,000 km or 5 years. Diesel engines typically use timing chains.
Engine Oil Spec Petrol:
Refer to Selenia Star (e.g., Selenia Star Pure Energy 0W-30 or equivalent API SN, ACEA C3).
Engine Oil Spec Diesel:
Refer to Selenia WR Forward (e.g., Selenia WR Forward 0W-30 or equivalent API SN, ACEA C3).
Coolant Type:

Brake Fluid Type:
DOT 4 (or DOT 4 Plus/LV for specific systems, always consult manual).
Transmission Fluid Manual:
Refer to specific manual for GL-4 or GL-5 specifications and viscosity, often SAE 75W-85 or 75W-90.
Transmission Fluid Automatic:
Refer to specific ATF specifications for Q-Tronic transmission, e.g., Tutela ATF Type 5.
Suspension Wear:
Wear on suspension bushings, ball joints, and tie rod ends, especially on higher mileage vehicles.
Electrical Gremlins:
Intermittent electrical issues can arise, often related to wiring harness integrity or sensor faults.
Dpf Issues Diesel:

Thermostat Housing Leaks:
Common on some GM-derived engines for plastic thermostat housings to crack and leak coolant.
Clutch Wear Manual:
Wear on the clutch assembly, particularly on manual transmissions, can be influenced by driving style.
