To use kerosene in a lighter, first verify the lighter’s compatibility with kerosene. Most standard lighters are designed for butane or gas, but some dual-fuel models can accommodate kerosene. Clean the lighter’s jet and wick with a cotton swab dipped in alcohol to remove debris. Pour kerosene slowly into the fuel chamber, avoiding overflow. Light the lighter and adjust the flame by turning the control wheel. Monitor the flame for stability; kerosene burns cooler and less efficiently than butane, requiring frequent refills. Always ensure proper ventilation to prevent carbon monoxide buildup.

Kerosene is a hydrocarbon fuel with a boiling point range of 150–250°C (302–482°F), making it less volatile than butane (boiling point -0.5°C/31.3°F). Its higher viscosity can clog small jets in lighters, reducing fuel flow. A 2018 study by the National Fire Protection Association (NFPA) found that 12% of home heating accidents involved improper use of kerosene, often due to inadequate ventilation or faulty equipment. Kerosene produces 2.5 times more carbon monoxide per liter than butane, per data from the Environmental Protection Agency (EPA). Lighter manufacturers like Zippo and Bic recommend against kerosene to avoid wick damage and flame instability. For optimal performance, use kerosene only in lighters explicitly rated for it, and prioritize safety protocols to mitigate risks.
