Short answer
MB 229.71 is a Mercedes-Benz Sheet on Operating Fluids for low-SAPS engine oil aimed at fuel economy in the latest generation of gasoline engines with modern emission controls. Approved products are predominantly SAE 0W-20. It is a separate approval from 229.72 and the older 229.52, and Mercedes publishes which products hold it.
What 229.71 is for
Mercedes developed MB 229.71 for newer engines designed around lower-viscosity oil. The sheet combines low sulfated ash, phosphorus and sulfur limits with fuel-economy-focused requirements.
Mercedes-Benz’s own genuine oil carrying this approval is an SAE 0W-20, and the products on the approval list are mostly 0W-20 as well.
229.71 versus 229.72 and 229.52
MB 229.72 is a related low-SAPS approval for specified modern applications. The two are listed separately and are not interchangeable unless your vehicle documentation says so.
MB 229.52 is the older low-SAPS sheet commonly seen on 5W-30 and 0W-30 oils. Some newer Mercedes engines list 229.71 first and 229.52 as an allowed alternative, while others accept only the 22x.7x sheets.
Cross-listed approvals
Many 0W-20 oils approved to MB 229.71 also carry other European approvals such as VW 508 00/509 00 or Porsche C20. Each approval is granted separately, so check that the specific one your car needs is on the label.
How to confirm the requirement
Use the owner’s manual or Mercedes service information for your engine, which lists acceptable sheet numbers in order of preference. Then confirm the product appears on Mercedes’ operating fluids list or names MB 229.71 in its current data.
Matching the 0W-20 grade alone is not enough, because the approval is tied to a tested formulation.
Frequently asked questions
Is MB 229.71 the same as 229.72?
No. They are separate Mercedes approvals and should be treated as different requirements unless the vehicle documentation allows both.
Can I use a 229.71 oil in an older Mercedes?
Only if that engine’s documentation lists 229.71. Older engines were not designed around these oils.
