Attention: TDR Forum Junkies Thought you all might be interested. I ran across this info last week - regarding studies of the effects of BioD on lubricity of various fuels, including kerosene, #2, mixes, and even jet fuels like JP-8.
Bottom line: 2% BioD pretty much makes anything meet the lubricity spec. . even kerosene.
Great news - as the numbers drop from marginally acceptable (dry #2, in the 400-500 ranges) to the 200s. That's significantly better wear protection for those expensive fuel pumps!
I'm thinking of keeping a container of it for trips as an additive when I'm not able to find it conveniently or running higher blends. That way if I get stuck, it'll make the junk out there good enough for the CP3. Even with a 40 gallon fuel tank, that 2% is less than a gallon.

First one is here: ROCLE Lubricity Numbers for Diesel and Biodiesel Fuels
Next one is a little longer and more detailed: Biodiesel Lubricity
This one includes JP-8, for those of you with access:
