>>2576222i managed to get it pretty good by adding a collar over the wick which keeps it tight. the wick still burns up but a lot slower and there's far less smoke. the reason i didn't want to use kerosene is cause i wanted to learn how to haw a decent light/heat source in a pinch. most homes have cooking oil, cotton string and a jar, but not all of them would have kerosene. but yeah you're absolutely right, canola oil is not fit for purpose.
