Complete Oil Specifications
The 2022 BMW 840i / 840i xDrive with the 3.0L turbocharged inline-6 (B58) requires oil meeting BMW Longlife-01 FE, Longlife-14 FE+, or Longlife-17 FE+, in SAE 0W-20 or 0W-30 viscosity, per the owner’s manual.
Why the Longlife Approval Matters
BMW’s Longlife specifications certify an oil’s long-drain-interval performance, particulate-filter compatibility, and turbo-lubrication properties specifically for BMW engines. The manual explicitly restricts which Longlife grades and viscosities apply to which engine — the 840i’s inline-6 (B58) is approved for the full Longlife-01 FE/14 FE+/17 FE+ list and both 0W-20 and 0W-30, while the M850i’s V8 is more restricted.
What We Couldn’t Confirm
- Engine oil capacity. BMW deliberately doesn’t publish a fixed fill spec for this vehicle — its electronic oil-level system displays the required top-up quantity on the Control Display rather than a table value, so there’s no fixed number to report.
- OEM oil filter part number. Multiple retailers cite differing genuine BMW part numbers for the B58 engine family; none could be confirmed on an OEM-owned parts catalog page, so none is published here.
- Oil change interval. BMW’s Condition Based Service system calculates this dynamically rather than publishing a flat mileage figure.
