Mercedes oil specifications

Mercedes approvals are used when selecting engine oils for Mercedes-Benz, AMG, Maybach, Smart and Daimler Chrysler.

Mercedes approvals

Mercedes Benz cars, trucks and buses have been renowned for their quality and position in the premium segment for over 120 years. That’s why Mercedes-Benz engine lubricants have to meet the highest requirements of today’s engine oil market.


MB Oil Specifications

The conformity of the oils with the manufacturer’s requirements is expressed numerically and alphabetically and is defined by the word “approval”. This designation is recorded in every vehicle’s service book and affixed to lubricant canisters, allowing the vehicle owner to use his or her own Mercedes engine oil of this particular type.

In order to obtain approval from Mercedes-Benz and the right to display its designation on the labels of the canisters, the engine oil manufacturer has to work hard. A manufacturer’s certificate certifies that the oil meets exacting standards. This is awarded following rigorous lubricant tests.

As a result, the engine oil is assigned certain tolerances, which determine the high quality of the product and its compatibility with the engine of a specific vehicle.

What is the Mercedes specification?

Mercedes specifications are symbolic designations for the properties of an engine oil for a specific type of Mercedes vehicle and it is by these that you select the oil for your Mercedes vehicle. By selecting oil according to the appropriate specification, you ensure that you are using the right oil for your Mercedes.
