just in case some of you haven't heard yet but mercedes has changed the engine oil they use in all cars since 1998 using synthetics. the old oil was mobil 1 0W-40. as of last week they changed it to mobil 1 5W-40. not sure on the reasoning yet but i am assuming the change was likely from another law suit.

a mobil truck came in on saturday to my dealership and sucked out all the 0W-40 and from now on 5W-40 is the only mercedes approved weight. not sure if this goes for the entire U.S. but i know it pertains to the northeast especially.
