Ive run mostly B20 in my diesels (which I sold and am now dieselless but hopefully not for long). I did notice some power loss but my fuel economy remained about the same. Also it didnt smoke much during startup. As for lubricating properties... depends on what research paper you read. Ive seen both sides of the arguement... some say it has just as good if not better lube as dino and other say it lacks. With what I was running I didnt see anything negative. One rig I ran with B20 for several thousand miles before I sold it.
As for now I am still between SVO and homebrewing some B100. Ive done a ton of reading on both.

I am running B20 in one of my BJ70's (AXT turbo'd) and I noticed the engine is quieter and no change in performance. I am not 100 positive but I think I am getting better mileage as well. I do not think you would see any difference in the BTU factor or mileage on B20 maybe more difference on B100.
