Can you put zippo lighter fluid in a jet lighter?

I wouldn't recommend it because the lighter fluid is just a liquid and the normal jet lighter fuel is a compressed gas. Having the gas compressed forces the gas out with the perfect amount of pressure. If you just put a liquid in it, it will just sit there and not do anything; maybe if you pressurize it and then make it into a fine mist when it comes out then it might work, but it wouldn't be too practical because it would be cheaper to buy butane than mod your lighter.
