What sucks is that sulfur is largely responsible for the lubricative property of diesel fuel. So the newer fuel will be less oily than the older. So, everyone who puts post-2007 fuel in a pre-2007 engine will be running fuel that is out of spec and will eventually kill their injector pump and injectors prematurely. That is, unless they add a fuel additive.
