Can you fill a Zippo with isopropyl alcohol?

While it is possible to fill a Zippo with isopropyl alcohol, it is not recommended. Zippo lighters are designed to work with lighter fluid, which is a highly refined and volatile petroleum-based product. Isopropyl alcohol, on the other hand, has a lower vapor pressure and may not evaporate quickly enough to ignite the lighter flame consistently.
Additionally, isopropyl alcohol may contain other impurities and additives that could potentially damage the Zippo lighter's wick or other components over time. Using lighter fluid specifically designed for Zippo lighters is the best option to ensure optimal performance and longevity of your Zippo lighter.

How do you light a Zippo without fluid?

It is not recommended to light a Zippo lighter without fluid as this may cause damage to the lighter or potentially injure the user. The Zippo lighter is designed to work with lighter fluid and is not meant to be used with any other substance. If you do not have lighter fluid, it is best to obtain some before attempting to light your Zippo lighter.
