Daimler MB 228.3

MB 228.3 is a 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 not fitted. These vehicles would typically align with Euro IV emissions standard and prior.

MB 228.3 lubricants are typically SAE 15W-40, 10W-40, 10W-30 and 20W-50 viscosity grades, based on API Group I or II base oils, with low levels of API Group III when required.

The main physical and chemical requirements for MB 228.3 are shown below:

Requirement Method Unit Limit
HTHS viscosity at 150°C CEC L-36-A-90 cP ≥ 3.5
Sulphated Ash ASTM D874 %wt > 1.0 and ≤ 2.0
Phosphorus ASTM D5185 %wt Rate and Report
Sulfur ASTM D5185 %wt Rate and Report
Evaporation loss (NOACK) at 250°C CEC L-40-93 % ≤ 13
Total Base Number ASTM D2896 mgKOH/g ≥ 8.0


MB 228.3 is usually grouped with a range of other approvals. The most frequently seen approvals claimed in conjunction with MB 228.3 are ACEA E7, API CI-4, MTU Type 2, Volvo VDS-3, Deutz DQC III-18, Caterpillar ECF-2 and Cummins CES 20077/20078.
