Your Mercedes-Benz vehicle requires specific fluids to avoid engine failure and to maintain its optimum performance.

Approved Engine Oils

Engine oil must satisfy many different industry standards and manufacturer requirements. The most common oil ratings are:

• API - American Petroleum Institute
• ILSAC - International Lubrication Standardization and Approval Committee
• ACEA - Association des Constructeurs Européens d'Automobiles

Mercedes-Benz has very specific engine lubrication requirements and only oils that have a MB approval number and the approved viscosity ranges are to be used when servicing your engine. The MB approval number will be marked on the oil container similar to what is shown in Figure 1.

For U.S. Vehicle Models prior to MY2007, please refer to the Factory Approved Services Products brochure on STARTekInfo.com.

Engine Oil Viscosity Range Chart

Select oil viscosity grades according to the lowest and highest air temperature expected before your next oil change.

Engine Type	MB Approval Number	Approved Oil Viscosity Range
113	229.5	0W-30, 0W-40, 5W-30, 5W-40
155 SLR	229.3	5W-50
156	229.5* or 229.51	0W-40, 5W-40
272	229.5	0W-30, 0W-40, 5W-30, 5W-40
273	229.5	0W-30, 0W-40, 5W-30, 5W-40
275	229.5	0W-30, 0W-40, 5W-30, 5W-40
642	229.51	0W-30, 0W-40, 5W-30, 5W-40

*156 engine using 229.5 should use only SAE 0W-40 oil

Use the table below to determine the MB approval number. Refer to the Operator’s Manual for the engine type of your model. The model and engine type can be found in the “Technical Data” chapter of your Operator’s Manual under “Engine."
