I've been fueling at Flying J lately and noticed they they use a B15 blend. Has anyone had any issue with this fuel mixture?

I know on my last 5.9L it was ok to run B15, but with the 6.7L and emissions crud that the feds say have to ornament the engine bay and exhaust system of the trucks now days, has anyone had problems with this mixture cloging any portion of the fuel/exhaust system?

I run a b20 in my 2002 all the time, no issues. On the 6.7L though I don't know. Seems, and this is just a wild guess, that a b20 would be fine in a 6.7L truck as most everyone(diesel engine folks) have seen the b20 coming for some time now and would have expected folks to want to be a little more green and fuel up with the b20. A quick call to the dodge dealer in the morning should give you an answer or even flipping into the owners manual.
