 Hi
 I don't recommend using an open flame with the oil.
I used an electric fry pan. I don't think peanut
oil has as low a flash point as many other oils. 
I believe that peanut oil has a flash point around 600F; 60/40 solder flows
at about 370F, so there's a pretty good safety margin, but the oil will
start smoking at temperatures around 450F.

Silicone oil might be a better choice (it's used a lot in commercial heat
baths), but it's not inexpensive. 
Solder and silicone oils are bad juju.  That would result in a 
solderability problem.

Myself the oil/fry pan is just duplication a solder pot with a 
meniscus (sp??) with the handicap of the oils nasty behavour 
and post removal cleaning needs.  The solder pot is somewhat 
safer if attention is paid to spilling.  It also has usefulness
in reloading the board if needed (heat and drop part in holes).
