Engine lubrication protection and internal component durability on the 2023 Mercedes S-Class are managed by Mercedes-Benz operational fluid specifications, synthetic oil formulations, and high-performance engine tolerances.
How to Fix It:
-
Check Operating Manual Specifications: Refer to your owner's manual or under-hood service sticker to verify the exact MB-Approval specification (such as MB 229.5 or MB 229.51/52) required for your specific engine variant.
-
Select Approved Synthetic Oil: Purchase a high-quality fully synthetic motor oil that explicitly lists the correct viscosity grade (such as 0W-40 or 5W-40) and certified MB approval code.
-
Avoid Non-Certified Oils: Refrain from using standard or non-approved mineral oils to prevent premature engine wear and emission system damage.
