Does anyone know if these two years can run on 100% biodiesel?

Thanks for your answers

Here is the Mercedes legal language:

With that said yes I'd imagine they can, but it could void part or all of any dealer or CPO warranty the car has.

I thought I had Heard Willie Nelson was running a 2005 on Bio alone but not sure of that. I was just wondering the prices are getting lower on the 2005 and 2006 might start looking after some extensive research.
I'm pretty sure the blue tech's can't be run on 100% bio so those would be the only years I would be interested in if they can handle bio.

OK, after some basic research I'm lead to believe the problem stems from the post-combustion processes designed to improve vehicle emissions on the BlueTEC cars. There's some discussion that higher blends of biodiesel won't burn the same in these processes as pump diesel and this can lead to engine oil being dilluted with biodiesel which indeed would lead to eventual engine damage, not covered under warranty.

no they cannot. any vehicle with common rail has too high of pressures for b100. b20 is the max i would ever run and have even seen issues with that

I'm curious, just looking to find out more information.

Can you explain the issues of high pressure associated with B100?

I know I have read of people running WVO in the CDI engines (longevity not known) but I thought they were running B100 as well.
