Thanks for the reply. I have no intention of running anything other than
BD. I am trying just trying to find out if unwashed BD will cause the
problems you mention. I am not worried about a small excess of Methanol as
the vehicle will be new. Do the fine filters you speak of remove residual
glycerin? and does the small amount left in a well reacted batch of BD a
concern (unwashed).
Thanks,
Ed
