I have been carrying a ZIPPO for many, many years. It has advantages that a BIC does not have. Some people say they don't like ZIPPOs 'cause they run out of fuel. Mine don't. Here's why I never worry about the ZIPPO "going dry" at the wrong time causing me major misery when trying to light a fire.
I don't smoke so don't worry about lighting 25 or 30 cigarettes each day. If I did, I'd use a BIC, too. As for a ZIPPO, I'd no more leave home for the boonies without "fueling up," than I'd carry my CCW unloaded.
I decided to try an experiment and here is the result. First, I filled my old ZIPPO to the brim. Then, I placed the rubber sleeve I cut from a bicycle tube around it so the top and body were completely sealed. (This is how I've been carrying my ZIPPO for many years with no problems.)
Then I marked my calendar as to the day I began this experiment. Each day, twice per day, I opened the ZIPPO and lighted it. I allowed it to burn 10 seconds per light, simulating lighting tinder for two fires each day. I always replaced the rubber tube. There were a few times when I lighted it several times per day when I was outside burning some papers in a burn barrel.
According to my calendar, the ZIPPO ran perfecty for 11 weeks, then went dry.
Then I opened one of the tiny Tabasco bottles in which I carry extra lighter fluid. They're in a small plastic bag, always stuffed in my day pack. I put one bottle in the ZIPPO. It was not filled to the brim. I followed the same procedure as noted above, lighting it always twice a day and sometimes three or four times. According to my calendar, it lasted for one day past four weeks.
I think that is pretty good performance.
Everyone carries what he or she feels is best, and a BIC can be mighty handy. But as I don't intend to stay out in the boonies for 19 weeks, I don't worry about my ZIPPO "going dry" and letting me down in a dire situation. Here is what my ZIPPOs with and without the rubber tube, and the Tabasco bottles look like. Note the flame. It was kinda windy outside where I took the picture. Think a BIC will do that?
(Yeah, I have two of them.
) Also the rubber tube makes the ZIPPO waterproof. Works for me
