My dealership would never have a deal like that, I don't like my stealership very well. I stock more parts for my 123 than they do for the 116, 123, and 126 combined (they also tend to charge more than retail). Odds are they don't even carry Delvac if they don't carry any parts for them then they must not work on them either. That is a good deal, it seems like delvac online is more like $100 for four gallons plus shipping. If the normal mobil 1 is no real different (it is intended for diesels as well) and I can get it locally and for cheaper I'd rather stick with it. That makes me feel much better that MB approves my 15w50 supersyn.
