How much do you know about the nuts and bolts of lighters? And, perhaps equally important, how much do you know about fuel for your lighters?
Today I am going to delve into the world of lighters and provide you with what you need to know about lighters and lighter fuel for survival.
The Mystique of Zippo Lighters
What I am going to say in this article was inspired by this honest to goodness dialogue I had online:
“I’ve inherited an old Zippo cigarette lighter from my grandfather. Can I use charcoal lighter fluid in it?”
It’s like a discussion with my wife about cheese balls. To me, a cheese ball is made from semi-soft cheese, is the size of a baseball, and is rolled in crushed nutmeats. To her, cheese balls are the size of marbles, made of puffy cheese-curl stuff, and contain orange dye that sticks to your teeth. Both are popular at parties.
Turns out there are different things named cheese balls. Likewise, there are different things named lighter fluid.
Lighter Fluid: Bad Information
The Internet question “Can I use charcoal lighter fluid in my Zippo?” received an Internet answer (but not from me):
“If you fill a Zippo with charcoal lighter fluid, you can kiss your eyebrows and nose hairs goodbye. And any other part of your anatomy that’s close to the explosion when it occurs.”
That answer is 100% wrong. It was followed immediately by a second 100% wrong answer: “Charcoal lighter fluid in a Zippo? No way. You must use butane.”
And a response: “Well, I finally got my Zippo apart but I still can’t figure out how to put in the butane.”
My take? As Albert Einstein said, “The difference between stupidity and genius is that genius has its limits.”
Zippo Lighters and Butane
Let’s deal first with the Zippo/butane thing.
Zippo lighters were patented in 1936 and saw their heyday with the GI’s of World War II. Zippos used liquid fuel (white gas). The tiny fuel tank was stuffed with cotton fluff so that the liquid didn’t spill into your pocket. A wick brought the fuel to the flame by capillary action.
Zippo’s reign as king of the lighters ended in 1973 when Bic introduced disposable butane lighters that could provide 3,000 lights before wearing out. How do you spell, “Goodbye Zippo”? Answer. “Flick my Bic.”
Today, a new Zippo and a small can of fuel, you can buy a package of five butane lighters (Bic knock-offs, pre-filled with fuel) for one buck at the Dollar Store. One Zippo and a can of fuel equals 78 butane lighters.
Judging by the Internet, people born after 1970 may have never seen a Zippo-style lighter. They sincerely believe that butane is the one and only fuel ever used in cigarette lighters.
So we need to understand butane a little better . . .
ABOVE (L to R): (1) disposable butane lighter; (2) refillable butane lighter; (3) butane refill canister; (4) to fill, hold both canister and lighter upside down, mate the fittings, push until it feels good.
Water boils and turns from a liquid to a gas at 212 degrees F. Butane boils and turns from a liquid to a gas at 31 degrees F. Just about the time ice is melting, butane is boiling. That’s why it’s a gas at room temperature. In a refill canister, butane is a liquid only by merit of the fact that it’s been put under pressure, not unlike an aerosol spray can.
You can get the butane out of its canister by:
- turning it upside down,
- holding it at a slight angle, and
- pressing the injecting needle onto a hard surface.
The butane comes out as a liquid but you can actually see it bubbling as it boils away. It will volatilize into the atmosphere far too quickly to be of any use in your Zippo. And you won’t like the way it smells either.
And Then There Is Charcoal Lighter Fluid
Okay. We’re finally ready to talk about charcoal lighter fluid which is also known as mineral spirits. If you remember, that was the original question. Can you substitute charcoal lighter fluid for Zippo/Ronsonol lighter fluid? And the answer came back, “No! It will explode.”
WRONG! But where does the idea come from that charcoal lighter fluid is explosive?
IT STARTS HERE: In an effort to hurry things along, charcoal lighter fluid is sometimes sprayed on a charcoal grill that is already burning.
Note: Let us be clear here. We’re talking about a CHARCOAL grill, not a GAS grill!
The lighter fluid doesn’t break into open flame because the burning charcoal itself only glows; no FLAME exists to ignite the fluid. (And ignition does require a flame or a spark. Don’t you remember dowsing your cigarette in a cup of gasoline to impress the girls?)
But, although no ignition takes place, the fluid gets hot. It begins to vaporize and smoke. It goes above its “flash point” but there’s still no flame to set it off. When it reaches its “auto-ignition temperature” (i.e. 473 degrees F where a flame is no longer required) – POOF!
The flameless preheating vaporizes a large quantity of liquid before ignition occurs. And that’s the problem. Half a teaspoon is not a threat to your eyebrows. Half a cup is a threat to your house. Flameless preheating does not get proper credit for the results.
No “explosion” can occur as long as mineral spirits remains at room temperature. At room temperature, mineral spirits is a liquid. And a liquid must vaporize and turn to gas before it can OXIDIZE . . . that is, combine with oxygen . . . that is, BURN.
This is Ninth Grade science.
Side note: To those not familiar with the term, “mineral spirits”, it sounds like it’s plural. It’s not. Mineral spirits is singular. It does take some getting used to.
Zippo lighter fuel is highly volatile. Technically it is flammable. It readily evaporates. At room temperature, vapors are always present that can be ignited with a flame or even a spark.
For all practical purposes, charcoal lighter fluid does not evaporate at room temperature and is termed combustible. Vapors are too few and far between to catch fire. Like candle wax, it must be preheated to the point of forming a vapor before ignition can take place. A match performs the preheating function as well as the ignition-of-vapors function.
As fuel in a Zippo, charcoal lighter fluid, like motor oil, will not work. Spinning the striker wheel will create a shower of sparks but the sparks won’t produce enough heat to vaporize the fuel. The lighter will not light, much less explode. Your nose hairs are safe.
How To Fill A Zippo Lighter
ABOVE (L to R): Refilling a Zippo:
- First pull the innards out of the case.
- Then turn the inner assembly upside down and lift the felt retainer.
- Insert the spout of the fluid can and squeeze.
- The juice flows out of the can and into the cotton fluff inside the lighter. The fluid can is simply a can. It is not pressurized like a butane canister.
Zippo Lighter Fuel Alternatives and Substitutes
But this brings up an interesting possibility. Although we can’t use combustible liquids (diesel fuel, kerosene, mineral spirits) in a Zippo, can we substitute other flammable liquids (gasoline, Coleman fuel, acetone)? Will they work?
But first, let’s address flash point, flammability, and combustibility.
“Flash point” is the lowest temperature at which a liquid can form an ignitable mixture in air. OSHA defines a combustible liquid as “any liquid having a flash point at or above 100° F.” Kerosene and diesel fuel are both “combustible.”
A flammable liquid has a flash point below 100° F. Coleman fuel (a.k.a. white gas) and gasoline are both “flammable.”
· Let’s start at ground zero. Zippo and/or Ronsonol lighter fluid. Do they work in a Zippo-style cigarette lighter?
· Coleman fuel. Does it work in a Zippo lighter?
Yes. White gas with a dash of perfume equals cigarette lighter fluid.
· Other flammable liquids. Gasoline (petrol), lacquer thinner, acetone – do they work?
No. At least not the way I’d hoped.
The problem is the Zippo wick.
Perhaps it is too small in diameter. Or too big. Or too dense. Or too fluffy. Or the wrong material (Zippo wicks are asbestos). After all, it was engineered to lift one specific fuel, white gas, from the fuel tank to the flame. Acetone was not a consideration.
BUT if you put two drops of acetone (or other flammable liquid) directly on the wick of a Zippo and spin the striker wheel, the acetone will ignite and burn for 30 seconds. And thirty seconds of live flame is not bad. Plenty of time to light a twist of paper or splinter of wood which can then be used to light your candle or your campfire.
Some common flammable liquids:
· VM&P naphtha (i.e. varnish makers’ and painters’ naphtha; naphtha is an alternate name for white gas).
· Gasoline (petrol to the Brits).
· Acetone (nail polish remover).
· Lacquer thinner.
· Denatured alcohol (used as shellac thinner and as fuel in marine stoves).
· Dry gas (methanol; a form of alcohol).
CAUTION: Alcohol flames are hard to see.
There’s an English chap on eBay selling IMCO lighters. Developed in the 1930’s, they’re made in Austria and appear to be Europe’s answer to the Zippo. From the eBay sales pitch:
“These lighters are a great piece of kit, they are more user friendly than a Zippo, cheaper and double up as a candle . . . Runs on Lighter fluid or Petrol . . . IMCO has produced and sold over HALF A BILLION (yes half a billion!!) lighters . . .”
In the interest of article completeness, I bought one. What intrigued me was the possibility of multi-fuel use. And, indeed, with its cotton wick, it operates on gasoline very nicely.
Unfortunately, someone might believe that “These lighters . . . double up as a candle.”
ABOVE Left: The set-up. I inserted the IMCO “candle” in a 5/8s diameter hole so it wouldn’t get knocked over. Center: All is well. Right: This happened suddenly at 15 minutes. Sorry the focus is poor; it caught me off guard.
So there you have it, everything you, as a prepper, needs to know about fuel for your Zippo lighters!
