The 2026 BMW 3 Series uses a 10,000-mile or 12-month oil service interval, with tire rotation, brake inspection, cabin filter, engine air filter, spark plugs, and fluid services scheduled at longer manufacturer-style intervals typical for this model line. The timing chain is not a routine replacement item on this BMW engine family, so it is generally treated as an inspect-as-needed component rather than a scheduled maintenance service.
