Zippo gasoline lighter, These are practical lighters, able to produce a flame even in windy conditions, and are renowned for being among the few lighters that still use gasoline as fuel. The gasoline is utilized through the combustion of its vapors, released through a wick drawing from a cotton ball impregnated with it. The use of original Zippo gasoline is recommended. A characteristic element of Zippo production from 1933 to today is the use of a code on the bottom and on the insert of each lighter, which identifies its year of production.

The current date coding system uses a letter and a two-digit number to identify the month and year of production.

• Letters A to L represent the month (A for January, B for February, etc.)
• The two digits correspond to the year they were created: 14 for 2014
