is this from your dealer? because 229.52 was not available until recently.
Dealers near me have for about a year topped selling Mobil 1 ESP for diesels (229.51) and are now selling 229.52 for what I believe is all engines.
Where do you get this?
your maintenance manual should provide oil spec by engine type.
Even the 2012 R class owners manual specifies the following:
R 350 BlueTEC diesel engine type 642 oil spec sheet 229.51
R 350 gas engine type 276 oil spec 229.5
so to all the posters and the OP. Look at your owners manual !
you can also search web for MBUSA information on this. It's not rocket science!



The diesels require a low ash formula, but the gasolines do not. The 229.52 is the new spec and should be followed for diesels because of the temperamental emission systems.
Is your R350 a diesel or a gasser?

For your R350 use the Mobil 1 0w40 European Car Formula. This is what the MB dealer used to sell before going to their proprietary brand. It is not suitable for diesels with particulate filters.
