It uses synthetic engine oil that meets BMW Longlife-01 (LL-01) specification, with the exact viscosity depending on the model year and climate—commonly 0W-30, 0W-40, or 5W-30.
Oil specifications for the 328i xDrive
The BMW 3 Series 328i xDrive has used different engines across its generations (notably the N20 in earlier F30 generations and the later B46). Regardless of the exact engine, BMW requires an oil that complies with the BMW LL-01 specification for petrol engines. Some oils also carry the LL-01 FE (fuel economy) designation. To ensure accuracy, always verify the exact grade and specification for your vehicle in the owner’s manual or via BMW’s official oil reference for your VIN.
Choosing the right viscosity
Viscosity recommendations vary by climate and model year, but LL-01 oils in this era are commonly found in 0W-30, 0W-40, and 5W-30. Colder climates generally favor the 0W-30 or 0W-40 options for easier starting, while warmer climates or higher-load driving may lead to 5W-30 or 0W-40 being recommended. The precise requirement for your car will be listed in the manual and can be confirmed with BMW’s VIN-specific guidance.
Before selecting oil, ensure it carries BMW LL-01 approval (and LL-01 FE where applicable). Using non-approved oils can impact protection, performance, and warranty coverage.
Common LL-01 approved viscosities you may encounter include:
- 0W-30: Often used for fuel efficiency and cold-start performance; must be LL-01 (or LL-01 FE) approved.
- 0W-40: Strong overall protection in a wide range of temperatures; LL-01 approved.
- 5W-30: Widely used in many regions; LL-01 approved.
These are typical examples of viscosities that BMW LL-01 oils may have. Always verify the exact grade for your specific vehicle and climate with the owner’s manual or via BMW’s official guidance.
How to verify the right oil for your car
Use these steps to confirm the exact oil requirements for your 328i xDrive:
- Check the owner’s manual or the vehicle’s service information for the recommended viscosity and LL-01 (or LL-01 FE) specification.
- Use BMW’s VIN-based Oil Finder tool (or contact a BMW dealer) to confirm the exact oil grade for your engine variant and production year.
- Inspect the oil cap or dipstick area for labeling such as LL-01 or specific viscosity numbers, if present.
- Choose a synthetic oil that meets BMW LL-01 (and LL-01 FE, if noted) and matches the specified viscosity.
- Follow the manufacturer’s recommended service intervals and oil capacity when performing changes.
By following these steps, you’ll ensure you’re using the correct oil for your BMW 328i xDrive, protecting the engine and maintaining performance.
Summary
The BMW 3 Series 328i xDrive requires synthetic oil that meets BMW LL-01 (with LL-01 FE as an option). The exact viscosity—commonly 0W-30, 0W-40, or 5W-30—depends on the model year and climate. Always verify the precise specification for your VIN via the owner’s manual or BMW’s official oil reference, and choose an LL-01/LL-01 FE-approved oil from a reputable brand. This ensures optimal protection, efficiency, and warranty compatibility.
