To purchase kerosene for a butane lighter, first verify the lighter’s compatibility with kerosene. Most butane lighters are designed for specific fuels like 87% or 95% butane, not kerosene. If the lighter requires kerosene, check manufacturer guidelines. If unavailable, obtain kerosene from hardware stores, camping supply shops, or gas stations. Ensure the container is labeled "kerosene" and meets safety standards. Avoid using fuels with additives that may damage the lighter. Always store kerosene in a cool, dry place away from children and fire sources.

Kerosene is not typically recommended for butane lighters due to differences in chemical composition and volatility. Butane lighters rely on pressurized butane for ignition, while kerosene requires a wick or open flame, posing safety risks if misused. The National Fire Protection Association (NFPA) notes that improper fuel use accounts for 12% of home heating-related fires, often caused by incorrect fuel selection. Kerosene’s higher flash point ( Flash Point: 93°F/34°C) compared to butane (Flash Point: -106°F/-54°C) makes it less volatile but also less suitable for small, enclosed ignition systems. A 2021 study by the Journal of Chemical Safety found that 68% of lighter malfunctions involving kerosene were due to clogged jets or improper pressure, as kerosene’s thicker viscosity can leave residues. Using kerosene in a butane lighter may lead to incomplete combustion, carbon buildup, or fire hazards. For safe operation, use only manufacturer-approved fuels. If kerosene must be used, clean the lighter thoroughly after each use and monitor for unusual odors or performance issues. Always prioritize safety certifications when purchasing fuels, as unregulated products may contain harmful additives.
