Would you buy a 2008 E320 bluetec diesel over a 2007? I live in the 45 state compliant area. How many miles between urea tankfillups? John

 

I have a 2007 Bluetec, and don't need the fluid, and so far am very happy with it. I have heard that the fluid has to be replaced at 10K miles when the oil change is reccomended. I will problably change my oil at 5K as at about 4K it is really black. It has only used about 1/2 a quart so far. Jim

 

10K intervals are too long for a turbo IMHO, 4-5K seems about right.
