I wouldn't try it with a prized zippo, but...

Lamp oil (like Ultra-Pure) seems to last forever in oil/kerosene lamps without evaporating away. Granted, they're probably a little more closed, and exposed to less heat...

I guess the real question is whether a lamp-oil soaked wick can be ignited from sparks. That I don't know, it may well require vapors, which by definition means evaporation. I don't smoke or own that style of lighter.
