Refueling and Fuel Issues

Types of Fuels and Their Pros and Cons

Lighters use various types of fuel, including

Gasoline: In the early days, gasoline was often used as fuel for lighters, but due to its peculiar smell, it is rarely used today.

Butane, Propane, and Petroleum Liquefied Gas: These fuels are pressurized and filled into the air storage tank. When released into the air, they absorb heat and vaporize, expanding rapidly, making them easily ignitable. They are currently the most widely used igniting agents.

Advantages and Disadvantages of Lighters with Different Fuel Types

Liquid Fuel Igniters: These lighters typically use gasoline or kerosene as fuel. Their advantage is that they can create a strong, long-lasting flame. However, they often require frequent refueling and may leak if not handled carefully.

Gas Fuel Igniters: These lighters generally use butane or propane gas as fuel. They produce a stable flame, and because the gas dissipates after burning, they are safer than liquid fuel lighters. However, they may not work well at lower temperatures.

Electronic Igniters: These lighters use electricity as their energy source. They are versatile and don’t require fuel. However, they need frequent charging and become unusable when out of power.

How to Solve the Problem of Difficulty Refueling Pen Lighters

Ⅰ.Pry up the new oil nozzle to the top.

Ⅱ.Take out the inner tank from the lower shell of the igniter. This is easily done by holding the windshield with your hands and then pulling out the inner tank.

Ⅲ.Open the fireproof felt at the bottom of the lighter.

Ⅳ.Slowly add lighter oil into the cotton in the inner tank, ensuring that you push the oil nozzle to the bottom to prevent leaks. When the cotton wick starts to seep oil, it is filled.


Avoid overfilling the cotton core, as excess oil can wet the flint and affect ignition. Also, take care not to get the lighter shell wet during refueling, as this can lead to burns during ignition. You can either wipe it clean or wait for it to evaporate before use.

Pen Lighter Ignition Problems

Frequent Fires

Frequent fires may result from improper valve adjustment, with the valve being either too large or too small.


 Adjust the valve to the appropriate size, typically by turning the adjustment screw on the bottom of the lighter.

Ignition Failure

If the lighter cannot ignite, it may be due to the exposed wire end of the wire inside the lighter not aligning with the air outlet or issues with the gas quality.


Check the wire inside the lighter to ensure it aligns with the air outlet. If other lighters can ignite, but not this one, the gas used may be problematic, and air supply may need replacement.

Flint Wear

Excessive wear of the flint in flint-based lighters can lead to ignition difficulties.


Regularly replace the flint.

Improper Maintenance

Lack of proper cleaning and maintenance can lead to dust and impurities clogging the air holes, affecting ignition.


Clean and maintain your lighter regularly.

In conclusion, a pen lighter is a valuable tool, but it can encounter problems. Understanding the causes and solutions for these issues, combined with regular maintenance and precautions, will not only extend its service life but also ensure your personal safety. Spending a small amount of time on maintenance and precautions will guarantee consistent, reliable performance, making this a valuable tool for various situations.
