When the lighter runs out of fuel, the first reaction is to throw it away. This manual explains how to refuel an empty lighter.
Steps

Step 1. Take any refillable lighter and make sure you have the right fuel for it
Not every lighter can be refilled, but Zippo lighters and expensive gas lighters are easy to refill. Some gas lighters are so powerful that they can ignite paper at a distance of 30 cm, and some can even melt a coin.
Method 1 of 2: Zippo Lighters

Step 1. Open the lighter

Step 2. Remove the cover

Step 3. There should be a felt pad at the bottom of the lighter, lift it up with a toothpick
There should be cotton wool filler under the felt pad. Open a container of gasoline for lighters and fill in the filler for five seconds.

Step 4. Place the lighter back in the casing and turn it over for one minute
Ready!
Method 2 of 2: Gas lighters

Step 1. Take lighter gas
Gas is usually supplied with a set of adapters.

Step 2. Locate the valve at the bottom of the lighter

Step 3. Select a suitable adapter and insert into the lighter valve

Step 4. Insert the stem of the gas cylinder into the adapter and press down on the lighter valve with slight force
If you do everything correctly, you will hear a barely audible noise of overflowing condensation. Don't worry, the cylinder won't explode, because the contents will cool down during refueling. Also, don't worry about small gas leaks into the atmosphere when refueling, they cool the lighter and your fingers, but it won't hurt you, and it only lasts about three seconds.
Warnings
- Fuel is extremely flammable, take precautions.
- Playing with fire is dangerous.
- Use lighters carefully.
