Just bought my first tank of bio, by accident after months of searching for it. Found it at BP, noticed the pump label while I was filling up. The label stated it contains between 5 and 20 percent biomass derived fuel. I've read many times to expect a french fry smell from the exhaust, but you can't smell ANYTHING from my 6.0 now, unless you literally put your face in front of the exhaust stream. Is this because of the cat?
I would say better safe than sorry. I changed mine and most people say yes regardless of the amount of bio. It's your truck so technically your call, but you are doing yourself and your injectors a favor to change them.

Good point, and will do. FWIW, I've used diesel kleen, howe's, or redline at almost every fillup from the day I drove it off the lot (for lubricity rather than cleaning). I'm hoping that has kept little residue from getting a foothold in the fuel system. The filters I'm running now only have about 5,000 miles on them.
