Every car comes with a service schedule set by its manufacturer, based on both time and kilometres. A logbook service follows that schedule for your exact model and interval, so the right parts are replaced at the right time.
You don’t need to return to the dealer to keep your new-car warranty. Under Australian Consumer Law, your warranty stays valid as long as the service is done by a qualified mechanic, follows the manufacturer’s schedule, and uses parts and fluids that meet specification. We tick all three boxes.
