I am a smoker and a Zippo user. Evaporation of fluid is a concern for survival situations, while i do have the Doug Ritter PSK, i have found a method to carry extra fluid in a small package. I get the cheap bic style lighters (the ones where you can see the fluid in them and are adjustable flame) and take them apart. Take off the metal piece, the wheel, keep the flint cut the ears off that held the wheel and unscrew the plug that holds the butane in. Take out the straw piece and snap the metal piece that comes out of the stopper off and there ya go. When the butane has all evaporated fill it with fluid and screw the plastic stopper in tight and there ya go. This is probably leaning more towards Zippo carriers out there but in a pinch it could be used to start fires as well as fill a Zippo. I've got one that i filled in December and by my eye it hasn't lost any fluid in over a month but i will continue to update this forum on it's status.

By the way this is my first post and I have found a lot opf very cool info on this site.

Thank you Mr Ritter and everyone that posts their experiences and insights on this forum for others to learn by.

Interesting

While there are commercial fuel carriers made to carry spare fuel for the zippo on a keychain or something similar, it's pretty common for people to come up with improvised methods.

Personally, I use empty tobasco sauce bottles from MREs <img src="/images/graemlins/smile.gif" alt="" />

I bought one of those little Zippo keychain fuel carriers, works really well. It has a little sleeve to carry a spare flint or two and will fill the lighter about twice. I only put in one spare flint since they last pretty long and fill it with fuel when I am going on a trip. It is very handy, I think it cost under $10.
It can be carried in a pocket safely. I keep mine empty unless I am going on a trip. Cheers and welcome to the forum <img src="/images/graemlins/smile.gif" alt="" />

I can’t quite tell if you are writing this tongue in cheek but I’m guessing that you are.
The containers I buy my fluid in are sealed up tighter than a drum and would blowup half my house every time I opened them if they could be sparked by runaway atomic friction rushing into the container.
The one time that I know of that you might be on the right track a little bit is if you are flying in an unpressurized aircraft at high altitude the Zippo is much safer than the other style of lighters that depend on the pressure of the fuel to work.
The change in pressure due to the altitude could cause the BIC types to burst, which could add some excitement to an otherwise boring flight.
I keep my plastic bottles from leaking by squeezing all or most of the air out of the bottle before a flight. My Deet is a good example it leaked on me once when I forgot to get the air out of the bottle but never leaks other wise. It still rides wrapped in a zip lock bag just in case something goes wrong since that is what saved me last time.

P.S. What kind of lighter fluid do you find works best for your Zippo lighters?
