For operating the Feuerhand 276 Moss Green lamp, a high-quality lamp oil with high fuel purity and no additives or perfumes is recommended, such as Feuerhand lamp oil or high-purity alkane paraffin oil. Lamp oils containing fragrances or dyes, as well as bio-oils, should be strictly avoided, as these can clog the lamp, gum up the wick, and lead to excessive soot buildup.
