Keep in mind that paraffin oil (wax oil, Nowell's, Ultra-Pure, Tropical Lights, etc.) may be marketed for oil lamps, but it may only burn half as bright of any of the approved fuels listed above. Paraffin oil is thick, and its flash point is 100 degrees higher than that of kerosene. This inhibits the capillary action of the wick, and will cause lanterns with a ⅞-inch or larger wick to burn improperly and erratic. Once a wick is contaminated with paraffin, it must be replaced in order to burn properly with a different fuel.
