The 2021 BMW M3 uses condition-based servicing, with engine oil due no later than every 10000 miles or 12 months, cabin and engine filters at approximately 20000 and 30000 miles, and spark plugs at approximately 30000 miles. BMW treats the transmission and coolant as long-term fills requiring replacement primarily for repairs or when indicated, and the engine uses a timing chain rather than a scheduled replacement belt.
