The recommended fluid change interval for the BMW 328i is every 100,000 miles. However, depending on the driving conditions, such as stop-and-go traffic or towing heavy loads, the fluid may require more frequent changes. Refer to your owner’s manual for specific instructions on the recommended interval for your vehicle.
