To use Zippo Fluid correctly, first clean the lighter’s interior with a cotton swab and rubbing alcohol to remove existing fuel. Next, unscrew the fuel cap and carefully pour 3-5ml of fluid into the chamber, ensuring it does not contact the wick or flame. Replace the cap tightly and shake the lighter gently. Test it by lighting the flame; if it fails, repeat the process with additional fluid. Avoid overfilling, as excess liquid can cause leaks or fires.

Zippo Fluid is designed to maintain consistent ignition performance in cold or humid conditions. The 3:1 ratio (fluid to lighter capacity) ensures optimal wick saturation without damage. A 2021 study by the National Fire Protection Association (NFPA) found that 22% of outdoor fires involving lighters were caused by improper fueling, often due to overfilling or incorrect fluid application. Zippo’s official guidelines emphasize ventilation during refueling to prevent vapor accumulation, which increases explosion risks. Additionally, using the wrong fuel (e.g., gasoline) can degrade the lighter’s components, shortening its lifespan by up to 40% compared to Zippo-specific fluid. Regular maintenance with proper fluid application extends lighter durability by 50% and reduces failure rates during extreme temperatures. The fluid’s paraffin-based formula also prevents rust, a common issue in unrefueled lighters, which accounts for 15% of mechanical failures annually. Adhering to these steps ensures safety, efficiency, and longevity.
