Go to Wendy's for the food if you like that sort of thing (I think they suck), but leave the french fry oil for the guys driving '06 and older VW TDI's. That juice is not for us. Personally, I wish it was but you can't cheat chemistry.

B-diesel is more electronegative than both the Dino and the lubricant. That means it bonds to the cylinder walls and gets into the sump and makes a mess. Also, B-diesel has a vapor point slightly higher than Dino and that trashes DPF's. For example, an '06 VW Golf with the 1.9l pump-duese can B100 all day long. The '09 VW Golf with the 2.0l CR can only run B10. The differences between the 2 motors, an HPFP (which is unaffected by bio-diesel) and a DPF that will fail.

My '10 Jetta TDI never saw a drop of bio and neither will my '11 d.

On another note ... I think the OP should run 3-4 tankfuls of B100 and then tell us how much a new DPF goes for. I've always wondered how much they cost.
