low sulfur fuel

[alex]

multi part question... i have 01 D/A CC 4X4 and am ready for new one. are the current LBZ designed with the new fuel in mind? do older engines need mods or additives? also does anyone know when new bodystyle HDs are coming?

I wouldn't worry about the fuel till 2010. The 2001-2006 engines will be able to deal with the fuel just fine - at least till then. The ASTM may formulate new fuel standards in the coming years specifying a lubricity component.

There's a mix of rumors floating concerning just when the new GMT-900 sheet metal might arrive. Some say the fall of 2006 - some say not till the 2009 model year.... I can't see the new Tahoes, Suburbans and Yukons being in production for 2-3 years before the 2500HD/3500 trucks get the new styling.
