Daimler issues their own set of requirements for service fill engine oils used in their Mercedes-Benz vehicles. These are compiled together into a single document which is periodically updated, either when testing requirements are changed or new specifications are added.
Each individual specification is known by its MB Sheet Number. For heavy duty diesel vehicles, the MB sheet numbers begin with the number 228 and for passenger vehicles with the number 229. The MB sheet numbers are all in a sequence beginning with the sheet number and ending with a two digit suffix denoting the specific specification. For example, in passenger cars the MB Sheet 229.3 is typically referred to as MB229.3.
The specifications detail allowable viscosity grades, ACEA or API level performance that must also be met plus additional physical, chemical and engine testing that must be conducted. This includes engine tests that have been developed by Daimler and chassis dynamometer testing fuel economy testing in specific vehicles for certain specifications.
All applications for approvals against Daimler’s specifications are made through Daimler’s online BEAM system. Daimler publish lists of approved lubricants on the Mercedes-Benz website.
