When I was at San Jose State in the late 60's Gordon Cruckshank had a kiln =
that fired with used motoroil.=3DC2=3DA0 He had the oil line running in the=
ulation of the arch to raise the temp of the oil reducing the viscosity.=3D=
=3DA0 He also ran the air supply inside the insulation of the arch to give =
me pre-heat to the air all of which aided the burning of the oil in a more =
efficient way.=3DC2=3DA0 His oil was supplied from a 55 gallon drum with a =
into the drum standing about 4 or 5 inches above the bottom.=3DC2=3DA0 The=

as a 12 volt electric fuel pump to pump the oil=3DC2=3DA0 to the burner.=3D=

He also had a filter in the line before the oil pump as I recall.=3DC2=3DA0=
ng a motorhead I liked the idea of using the auto fuel pump to supply the o=
il and a spin on filter adapter (As used in old cars that did not come with=
the newer spin on filter system from the factory).=3D20

The oil filter really lasted a long time because if the oil is not agitated=
then the heavier contaminants will settle to the bottom of the drum (hence=
having the pick up some inches above the bottom).=3DC2=3DA0 I have a few=
vintage motorcycles that sump (allow the oil to drain into the crankcase wh=
