For what it's worth, I have two Countycomm peanuts and a split pea. When I check them every few months, they light on the first try and won't take more than a tiny bit of a refill.

Finding fuel is usually easy. Sometimes finding flints is hard. An old trick I learned with Zippos is to stick a spare flint in the bottom of the lighter. You lose a little bit of fuel capacity but for me it's worth it.
