does anyone know how these ULSD fuels will affect the performance and efficiency of our old mercedes diesels? is it beneficial or no effect? from what i have read in some auto magazine article, that european diesel fuel are the best kind of diesel you could ever find in the world and what US diesels like what were burning, is said to be also known as "dirty diesel". so, if the ULSD fuel which has euro specs on it, and will be introduced to the US, what are its advantages aside from environment and air friendly?
