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

Thanks for your answers

Here is the Mercedes legal language:

Quote:
Mercedes-Benz approves the use of B5 according to ASTM D975 (standard Ultra Low Sulphur Diesel (ULSD) with a maximum of up to 5 % biodiesel) in all Common Rail Injection (CDI) and BlueTEC diesel engines.

The only approved processed biodiesel for B5 blending is one that meets ASTM D975 specification to prevent damage to the engine system from deposits and / or corrosion.

Diesel fuels containing a higher percentage of biodiesel, (e.g. B6 to B20) according to ASTM D7467 as well as straight biodiesel (B100 / 100%) ASTM D6751 may cause severe damage to your engine/fuel system and are not approved.

The Mercedes-Benz Limited Warranty does not cover damages caused by the use of fuels that do not meet Mercedes-Benz approved fuel standards.

Mercedes-Benz vehicles must only use qualified commercial brand fuel that meet Mercedes-Benz approved fuel standards!
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.

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.
