Mercedes-Benz MB229.5

MB229.5 oils are Upper Mainline high SAPS¹ lubricants designed for use in high performance gasoline and light duty diesel engines without advanced aftertreatment systems such as Diesel Particulate Filters (DPFs).

MB229.5 oils are typically SAE 5W-40, 5W-30 or 0W-30 based on API Group III or a mix of API Group III and Group IV base oils.

The main physical and chemical requirements for MB229.5 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 ≤ 1.6
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	%	≤ 10
Total Base Number	ASTM D2896	mgKOH/g	≥ 10.0

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

MB229.5 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 MB229.5 being ACEA A3/B4, BMW Longlife-01, Volkswagen 50200/50500, Renault RN0710, Renault RN0700, Peugeot B71 2296 (5W-40 only) and Porsche A40 (5W-40 only).
