Honest question, how long is the fluid supposed to last? And I'm not talking about burning time. I have a zippo, I fill it, a few weeks later I go to use it and the flame lasts a few seconds as the fuel finishes.
You need to recharge it like every week, no need to be "zippo fuel" with any crappy benzine its ok.
Its hard to get out of fuel by use, use it or not will last allmost the same time.
