Daimler MB 228.61

MB 228.61 is a Top Tier low SAPS¹ lubricant specification designed for use in high performance medium and heavy-duty diesel engines where advanced aftertreatment systems such as Diesel Particulate Filters (DPFs) are fitted. With a HTHS viscosity of 2.9-3.2cP, these lubricants are designed to provide enhanced fuel economy benefits to the latest Daimler OM471A Euro VI engines.

MB 228.61 lubricants are typically a SAE 5W-30 (2.9-3.2cP) viscosity grade, based on API Group III base oil.

The main physical and chemical requirements for MB 228.61 are shown below:

Requirement Method Unit Limit
HTHS viscosity at 150°C CEC L-36-A-90 cP ≥ 2.9 and ≤ 3.2
Sulphated Ash ASTM D874 %wt ≤ 1.0
Phosphorus ASTM D5185 %wt ≤ 0.12
Sulfur ASTM D5185 %wt ≤ 0.4
Evaporation loss (NOACK) at 250°C CEC L-40-93 % ≤ 12
Total Base Number ASTM D2896 mgKOH/g ≥ 7.0

Note 1: SAPS refers to Sulphated Ash, Phosphorus and Sulfur, the levels of which are often restricted in the latest performance specifications.

MB 228.61 is usually grouped with a range of other approvals. The most frequently seen approvals claimed in conjunction with MB 228.61 are API FA-4, Detroit Diesel DFS 93K223, Cummins CES 20087 & Ford WSS-M2C-214-B1.
