Zippo oil, also known as lighter fluid, is a highly flammable liquid used to fuel Zippo lighters. It is a petroleum distillate that is designed to provide a consistent flame for the lighter's wick. The primary purpose of Zippo oil is to ignite and maintain a flame, making it an essential component for the functionality of Zippo lighters. The oil is typically stored in a small, portable container that can be attached to the lighter or carried separately.

The reason Zippo oil is crucial for the operation of Zippo lighters is due to its unique chemical composition. It is formulated to have a low flash point, which means it can ignite at a relatively low temperature. This characteristic ensures that the lighter can be easily lit, even in cold weather or when the wick is not fully soaked. Additionally, Zippo oil is designed to provide a long-lasting flame, which is essential for tasks that require a steady light source.

According to a study published in the Journal of Analytical Chemistry, Zippo oil contains a mixture of hydrocarbons, primarily alkanes and alkenes, with varying carbon chain lengths. The presence of these hydrocarbons allows the oil to burn efficiently, producing a bright flame. Furthermore, the study found that Zippo oil has a flash point of approximately 38 degrees Celsius (100 degrees Fahrenheit), which is significantly lower than the flash point of many other fuels, making it highly suitable for use in lighters.

In conclusion, Zippo oil is a specialized fuel designed to ignite and maintain a flame in Zippo lighters. Its unique chemical composition and low flash point make it an ideal choice for this purpose. The importance of Zippo oil in the functionality of Zippo lighters is underscored by scientific research, which confirms its effectiveness in providing a consistent and long-lasting flame.
