Fuel safe tubing is the way to go- there is also a black rubber tubing used here in the states- I don't think you want the water soluble mould release oil, as IMHO it wont smoke. The key ingredients in Super dri are mineral spirits, and Paraffin. You know, wax- like a candle. I think the mineral spirits thin the consistency of it to where it will flow correctly, and aid to heating quickly enough to atomize.

Another item worth noting, is don't flood the exhaust with too much oil, as it will cool the exhaust, and also I had an engine (50cc) that did not like where the oil was piped into it- it bogged the engine down, as the atomization was creating some sort of back pressure within the can. I moved the inlet, and all was good- Experimentation is the name of the game, so have fun!!!
