Just discovered a bit of information that may be found useful.
Before refilling your lighter, press down on the refill point with a paper clip or ball point pen, and release all air from the chamber.
Chill your lighter in the freezer for 30 minutes. The reasoning here is that the butane escapes from the refill can at a very cold temperature, and the refill works better when the lighter is closer to that low temperature.
Fill the lighter with the butane refill can pointed downward.
Allow enough time for the lighter to return to room temperature (holding it in your hand for several minutes works well) before attempting to light it.
