MB229.3 oils are typically SAE 5W-40 or 5W-30 based on API Group III or SAE 10W-40 based on API Group II base oils.

The main physical and chemical requirements for MB229.3 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	> 0.9 and ≤ 1.5
Phosphorus	ASTM D5185	%wt	≥ 0.05 and ≤ 0.11
Sulfur	ASTM D5185	%wt	≤ 0.5
Evaporation loss (NOACK) at 250°C	CEC L-40-93	%	≤ 13
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.

MB229.3 is usually coupled with a range of different combinations of other approvals depending on the viscosity grade of the lubricant, The most frequently seen approvals claimed in conjunction with MB229.3 being ACEA A3/B4, Volkswagen 50200/50500, Renault RN0710 and Renault RN0700.
