Service on warranty

As others have said use a MB filter if under warranty (otherwise I have always used Mann as most OEM oil filters are made by them) and document your purchase of the correct spec of oil for your car. 229.51 is easy to find at most parts stores the best price I have found is NAPA Mobil one 0w-30 (5.99 on sale) its a new oil but still meets 229.51 as well as the new 229.52 for the 4 bangers. I am about 4k into my first oil change with that oil.
Putting my MOD hat on you have a w212 so I moved the thread to the proper location.
