Mikesolar,

Ordinary, gas station cylinder exchange propane works just fine as well as being cheaper than the small bottles of torch or camping gas. The main issue is getting the mercaptan "stench oil" out of the propane. For added insurance, you should have some sort of filter-drier in your liquid line as well.

I am stumped as to the claims being made on the petroleum industry and their so-called lack of quality. Non-spec "commercial grade" propane is not sold to the public. It has been deliberately formulated for the customer it is being sold to. The plastics industry uses ethane/propane blends, while the welding gas industry uses propane/propylene blends. The petrochemical companies make good money separating all these gases from each other and blending them back together. Just look at the refrigeration industry!
