I searched but couldn't find anything relevant.... Anyone got comments on the best oil for the Aurion? Booked mine in for the first service since buying it and the dealer uses Castrol FMX, does anyone know if there's a more ideal or better quality oil? Prefer synthetic and dont mind what it costs (within reason). Got an auto tranny oil change as well cos I know the old owner &don't know what it would be like after she drove it. Plus its always good to have some fresh oil. Cars done 38,000kms.
