So I bought myself a 6700 a couple years ago and I never carry it because it evaporates fluid so quickly. I don’t smoke so I won’t use it frequently enough to justify refilling it all the time just to keep it full. Are there any alternative fuels out there that won’t evaporate so fast? I thought maybe lamp oil but I read that it doesn’t take a spark well enough. If not, does anyone know any tricks to keep typical lighter fluid from evaporating? I’ve read things like using a piece of bicycle inner tube around a Zippo to help keep it air tight, but I’ve never heard any tricks for an IMCO.
