The 2026 BMW 3 Series uses Condition Based Service, with oil service generally due at 10000 miles or 12 months and additional filters, brake fluid, and spark plugs scheduled at longer intervals. The engine uses a timing chain rather than a routinely replaced timing belt, so inspection is recommended instead of scheduled replacement.
