How often should you refuel a zippo lighter?

The regular ones not zippo blue. Also what stores sell fuel and how much is it?|||Refueling depends on how much you use the lighter. Refill it when it goes empty as if you try it when you feel like it, it may not need filling and will just run out of the container. There are a lot of stores that sell the fuel, you just have to look or ask. Wal-Mart, Kmart, the dollar stores, grocery stores, etc. The stores set the price so it would be hard to give you a price but I think the stores just mentioned would be the lowest in price|||just refill it whenever the flame begins to flicker out i used to top it off once a week


as far as stores: Walmart, any conveince store and tobacco shops should carry lighter fluid.
