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 am curious if other board members run straight B100 in their 98 or 99's and if so:

for how long they have done so?

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

if our cars use the "viton" rubbers in fuel related lines, hoses, o-rings etc?

Thanks
