I have owned a Zippo for many years and I have never had a problem mechanically. However, I do find that the fuel evaporates awfully quickly. <br>I was suprised to learn that they will run on gasoline.<br>Will a Windmill Waterproof Butane Lighter do the same?<br>I am currently trying to get as much info as I can comparing the two different types as I am in the market for a new lighter.<br>At the moment I use the BIc lighters. I have some that are 5 years old and still work flawlessly and still have fuel in them.
