If you own an X3 xDrive20d or xDrive30d, you must use oil meeting BMW LL-04 specifications. Using a petrol-specific oil in a diesel model, or vice versa, will lead to suboptimal performance and potential system failures over time.
BMW X3 Oil Type LL Standards: Ensuring the Right Formula for Your Engine
