Daimler MB 228.52
MB 228.52 is a Top Tier low SAPS¹ lubricant specification designed for use in select Euro VI / US Tier 4 engines used in buses and industrial/off road applications where advanced aftertreatment systems such as Diesel Particulate Filters (DPFs) are fitted.
MB 228.52 oils are typically SAE 10W-40, 5W-30 or 10W-30 viscosity grades based on API Group III, Group III + II or Group III + Group IV base oils.
MB 228.52 shares many common characteristics with MB 228.51. The major difference between the two specifications is that MB 228.52 has a restriction on the level of calcium allowed in the lubricant and is designed for use in select applications/engines mentioned above.
The main physical and chemical requirements for MB 228.52 are shown below:
|HTHS viscosity at 150°C||CEC L-36-A-90||cP||≥ 3.5|
|Sulphated Ash||ASTM D874||%wt||≤ 1.0|
|Phosphorus||ASTM D5185||%wt||≤ 0.08|
|Sulfur||ASTM D5185||%wt||≤ 0.3|
|Calcium||ASTM D5185||%wt||≤ 0.15|
|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 228.52 is usually grouped with a range of other approvals which may vary depending on the viscosity grade. The most frequently seen approvals claimed in conjunction with MB 228.52 are ACEA E6, CK-4, MB 228.51, MAN M3775, MTU Type 3.1, Volvo VDS-4.5 & Deutz DQC IV-18 LA.
