U.S. gasoline, too dirty for the new Mercedes engine

The continual development of technology to enable more efficient engines make the tolerances they are dwindling. If a Mercedes-Benz 300D with previously filtered frying oil (certified by the MythBusters), gasoline engines new generation of Mercedes-Benz may not work with U.S. gasoline.

Do you know the nationality of motor gasoline? Well ... yes, each fuel, depending on where appropriate has a number of specific features in the case of U.S., sulfur is the problem. U.S. gasoline have an average of 95 ppm (parts per million) of sulfur, this is twice what the new generation Mercedes engines, based on lean combustion and direct injection stratified, can tolerate, since the sulfur can clog the filters that trap nitrogen oxides.

Mercedes-Benz will not sell these engines in the U.S. until it can ensure their integrity, but U.S. will not only be the only run out of these engines, and also in Asia and Africa gasoline may have an excess of sulfur. The first engine with this technology is the 3.5 V6 Mercedes C 350 (to be sold in the U.S. as "BlueDirect" but without the new technology) and the Mercedes SLK 350, so far in the United States will be without the SLK 350 to Pending a more thorough refinement of its petrol.
