Well actually yeah, that was one snafu with all of it...

You would probably do well to find Ma and Pa type places and make an
agreement with them to come at scheduled intervals...the Big McD and
others I am sure have cost effective ways of dealing with it...

Additionally, after reading other websites about this, it would take a
huge amount of storage in your garage/backyard for the "refining"
process of that oil to settle and get the yuckies out of it...labor
intense, but my labor for what I do is cheaper than gas these days :-)

I am looking at dumping my larger vehicles despite need for seating of
my 6 children...the Vanagon holds us just fine and gets round 20
mpg...

Gas that I can "make" with agreements could do a good supplement to
the diesel....

There still have to be more cost effective ways...what about electric,
hydrogen, egg shells???
