OM606.962 and BioDiesel

My 99 E300 seems to like fuel additives, typically idling quieter and getting slightly better mileage than without.

I have expirimented with adding ~1% of B100 and get the same results.

I would like to run straight B100 occasionally and am curious if other board members with 98 or 99's do so successfully, and if so:

How long they have done so?

Whether or not they have have had any mechanical issues they could attribute to use of B100?

Finally, does the 99 use the "viton" rubbers in fuel related lines, hoses, o-rings etc?

Like most other E300 TD owners, I don't want to go through another round of air infiltration into the fuel system.

Thanks

I've been running B15 off and on for about a year now. Those stupid plastic fuel lines around started leaking, but not sure I can blame that on the bio because they tend to leak anyway. No problem with the return lines so far. Lightman has run B100 in his E300 at least once and he raved about it. He said it ran so quiet that it sounded like an electric motor.
