Andrew,
will find much information and disinformation on the topic of BioD
here and elsewhere. (for example, the horror stories you hear about BioD
eating fuel lines; i've got over 70,000 miles on almost exclusively
straight BioD on the same fuel lines that were in my '85 300D when i
started using BioD over 7 years ago, and there still hasn't been any
evidence of any need to change them. all you need to do if you're using
quality fuel is watch them like you'd watch any other fuel lines from a
previous decade, and change them out when they show signs of needing it.)
as for availability of source oil, it's unlikely that anyone
outside of your area will be able to tell you what the actual
availability is in your area, and even then it'll vary from restaurant
to restaurant. (generally, cleaner/less used WVO is better; sushi joints
usually have cleaner and less overused oil than burger joints.)
bottom line, if it's only cost effectiveness you're looking for you
have to figure out if it's even worth it to you to go through the
hassles of making BioD. even if the source oil is free and your time is
worth nothing, how much would you need to use before the savings would
pay for the equipment and the energy to run it? if you're only using
~10G/wk, it'd be over a year before you even paid for the equipment, and
we're still not counting the cost of any of the chemicals.
(i'm not even going to get into the byproduct waste disposal issue
or the concerns about having some of those chemicals around, or the
mess,... and am ignoring the fear-mongering about jackbooted thugs hired
by renderers or our guvernment coming through your doors due to
perceived tax and various regulatory issues. but if you check into it,
you might find we can't even legally haul WVO without a renderers
license and liability coverage!)
if you're trying to use BioD for other reasons (like reducing
petroleum dependency, environmental concerns, or just the joy of
experimental hobbying,) your calculations of whether it's worth the fuss
might be different. in that case, i'd probably encourage searching our
your local B99 vendor and buying commercially produced stuff, and let
someone else deal with all the issues.
cheers!

We own three W123 turbodiesels so this is very tempting. Cost is about
$1700 + $450 more for the "dry washing" feature. We have lots of
restaurants that probably would be happy to get rid of their fryer
grease; the main snag might be the cost and ease of obtaining NAOH (caustic
soda). I also wonder how much lye and water is consumed per batch, and what
the brew would do to our fuel lines.,
