The whole problem is that the overall efficiency of Rudolph Diesel's engines are going backward with the addition of emission hardware.

Daryl,
I cant say your facts are incorrect, but their not a fair blanket statement.. You wont melt pistons or valves, nor will you throw a rod or anything of that sort from running ULSD.. However, the emission components you mention are more than just cats.. The engines themselves are changing in order to accomplish the lower emission standards.. The fuel is just a portion of it.. Some MFG's may not need to make major changes, but others will.. Just for an example, the Navistar built 6.0L in the Ford trucks was designed for emission compliance.. Thats why the 7.3L went away.... The 6.0L design incorperated a similar injection system, but added an EGR and variable turbo(among other things) to meet emissions.. The 6.0L will not meet the '07 standard.. You wont see an '07 Super Duty with a 6.0L in it(maybe an '06 built in '07, but not as an '07 truck).. The new engine had to change to common rail and add more coolers and another turbo..
So, back to your point you are correct that the new fuel wont destroy your engine.. But they are changing to meet the standard.. The trucks and tractors already out there will be fine...Even a few years ago, we had issues with the cats clogging from too high a sulfer content in the fuel... Run LSD and it fixed itself.. The newer engines will require a particulate filter wich is like a super cat.. It actually needs to be baked to clean it.. Some will require it for maintenance.. There is also a strategy in the EEC system that will run it rich in order to burn it off w/o extra maint.. There is also new tech coming in the form of urea injection to further reduce the emission levels.. One can do allot of damage with the wrong fuel, its up to them to decide how much is required to "destroy" it iin their mind... It I needed to pay $5k to repair my engine/emission system because of the wrong fuel, I can see where that could translate into " it blew my engine up" even though it may not be technicaly so..
Also, Bio diesel may not be (across the board) damaging... But, wether anyone believes it or not, there are concerns from it.. It may just be bad batches, but that must be taken care of and eliminated before it becomes widely accepted.. There are lobyists on both sides, so most of the info out there is propaganda... I can promise everyone, this is not a lie or an oil company conspiracy.. Groups have been formed to study the effects and what needs to be dont to eliminate them..
And lastly, the picture shows what I and others stated.. The LSD is being sold at that station, they need a lable to inform the consumer that if they put it in their truck designed to run ULSD, it can severely damage the engine(components)..
