The 2026 BMW 3 Series uses Condition Based Service, with oil service required at no more than 10000 miles or 12 months and major items scheduled by mileage or time. The engine uses a timing chain rather than a scheduled-replacement belt, so replacement is not normally required unless inspection identifies wear or a fault.
