Unfortunately direct injection injector fouling is not thoroughly understood
(completely different mechanisms that PFI). Compounding this, at least in
the USA, is high sulfur fuel that may never get legislated away. The
lobbyist have put enough loop-holes in that even in 2010 you could get a
slug of sulfur while refiners meet district average targets. How the engine
manufacturers are going to handle warranties is an interesting question.
