My unscientific theory is that white lighters are less likely to work. The bic lighters that have all the cool designs on them are actually a plastic wrap, and as they get older the wrap tends to peel away and eventually reveals a white lighter. So, it stands to reason that if you have a white lighter it is probably older, and older lighters are more likely to be low on fuel.
