Dyed fuel plugging filters is a myth. ULSD and biodiesel plugging filters when you first change over is not a myth. Dyed fuel is no different other than the color. ULSD and biodiesel however have a higher natural sulvency and tend to break all the gunk and deposits loose in a fuel system and many people experience filter plugging within the first few tank fulls. After the system is run on it for a couple of tanks the gunk is cleaned out and the problem goes away.
I dont believe its quite that simple.. The dyed fuel starts out the same, but the storage methods greate major trouble in ALOT of cases. The condensation from above ground tanks, rust, algea growth, separation of the fuel are all valid arguments against running it. However, if you can trust your suplier and the storage method, its just as good as the un dyed stuff..
As for Bio, having heard rumors of inavailability due to a cold snap here in Ga(30*F), I decided to test it.. I took a sample of 100% chicken fat bio diesel, 20% vegie, and ULSD and put all 3 in the freezer. After 1hr, the B100 was the consistancy of Jello and the others were still liquid. Over night, the B100 turned to a Crisco like lard while the
B20 showed serious signs of thickening(similar to eggdrop soup). The ULSD remained as liquid as when I put it in the freezer which BTW gets down to -10*F. Not a scientific test by any means, but circumstances can play a huge roll in whether a fuel can cause trouble clogging filters.. The filteration is supposed to be the main issue with the Bio because of the chemical variation of its consistancy.. As I have been told anyhow, that topic is a bit over my head...
I dont totally disagree with your point, it just seemed a little cut and dry.. Hope you dont mind my addition..
BTW, I believe in the additives.. Good measure...
