Hey Alvin, I hope all is well. The owner at the place where I bought the B100 told me that the # in the B20 would mean 20% bio & 80% regular diesel. I could only find the B20 up here as well. The posts I read said the B100 worked the best so I figured I'd give it a try. I can always dump it in the Kubota if it doesn't do the trick , but so far so good. See ya! Mark
