Just as an FYI.

Mercedes has now stated that both 0W-40 and 5W-30 are acceptable weights of SYNTHETIC oil to put in any Mercedes engines. Since Mobil 1 has reduced the production of 0W-40, 5W-30 is also acceptable. However, just cause I'm OCD, I would still use Mobil 1 5W-30... Fleece filter is also a good idea. I went with a K&N and it worked for me.
