Oil lamp fuel is made from isopropyl alcohol and distilled water. Essential oil may be added to give the lamp oil a pleasant aroma. The isopropyl alcohol is available in most stores that carry rubbing alcohol. The isopropyl alcohol has an alcohol content of 91 or 99 per cent. Rubbing alcohol does not work well to make oil lamp fuel. Mark the container the mixture is stored in, so it does not get confused with rubbing alcohol.

Pour 1 tsp of distilled water into the bottle of isopropyl alcohol.

Pour 1/2 tsp of essential oil into the bottle of isopropyl alcohol.

Replace the lid on the bottle. Shake vigorously to mix the contents.

Label the bottle. The homemade oil lamp fuel is ready to use.
