Installation Notes and Tips

Verify the owner’s manual or service data before filling. Use only where the vehicle calls for 5W-40 and the required approvals or specifications match this oil. For fitment-based service, confirm the exact model year and engine code, especially on Mercedes-Benz Sprinter, AMG, and Porsche applications. Drain the old oil fully, replace the filter per service procedure, and check the level after the engine reaches operating temperature.
