Thank you for all the tips. I was on vacation and could not get back to you earlier. As my problem is concern, I replaced the air, oil, and the fuel filter (all from MB dealer) and the smoke still persit. I'm going to the MB dealer today to acquire the additives that you recomended. Now what can you tell me about adding kerozene to the disel? I was told that one gal. of kerozene for each fillup.
Thank you againg for your help.
