Since oil has 3 times the btu potential of alcohol I am somewhat curious if any here has played with it?
I grabbed some lamp oil not to long ago and played with it a bit so here are a few of my comments...
Much harder to light, Almost impossible with out some type of wick
Tends to soot up a lot if not enough air availible.
Burns alot slower then alcohol.
If a light and workable design could be done then it would cut fuel weight by maybe half - just a random neuron at work......
