Xikar’s Premium Butane is a great way to keep your lighters filled and functioning properly. It is refined over and over, until it has damn near zero impurities. In fact, less than 15 parts per million (!) are impure, giving you an insanely clean can of butane that’ll prevent your torch lighters from clogging, extending its overall life in the process.
Each small can contains 1.9 oz of butane.
Now in giant, 400 ml (13.52 fl oz) cans! The size of 4 smaller cans for just a couple of bucks more.
Over the years, I've found that I've had less issues with my lighters by using Xikar butane fuel. It doesn't matter how many times other brands say they are refined, it is the manufacturing process that matters and Xikar nails it.
