Hey greaser, since we're talking Zippos...I have one that isn't reliable. I can fill it up with Zippo fluid and a week later it's hit n miss...most often bone dry in under two weeks. I don't use it much as I'm a non-smoker. And it's not my first Zippo, just so unreliable I pack other lighters instead. Know any tips or tricks to stop this fluid loss?
Take the packing out from under the felt then replace it with cotton balls you should get around a week or two after that.
