Great tip, thanks!
I'm going to put some Isopropyl rubbing alcohol (70%in my penny can stove tonight to see how it compares to the lighter fluid.
Why? Just because 16oz of Rubbing Alcohol costs $.99 and 4oz of Zippo lighter fluid costs $1.99.
Well, I started before I even pushed "post reply" and already the experiment is a failure. Apparently 70% alcohol is not nearly enough. I can't get it to burn any where except for the main fill hole, and you'd even have trouble lighting a cigarette from that. Well, that was a good lesson to learn before I needed it.
