I must have the only MB in the world that does not bellow, belch, or blow huge clouds of black smoke. I never get black smoke, even at WOT...no smoke. Therefore, all YOUR MB's must be out of adjustment.
Black smoke = unburnt fuel....heck it even still smells like diesel. And every time I see it, I think....what a waste! Frankly, I don't understand the sense of pride some have in being able to produce these "big black clouds of smoke" when merging on the freeway. Why does wasteing fuel and spewing black smudge over other motorists seem fun or cool?? My rant for the day is now ended.
