Abstract An emergency alternative fuel for internal combustion engines is stable for storage for a year or more. The alternative fuel is stored in a container which has an outlet sealed with a removable seal. The container is prevented from being reused for storage after the seal is removed. The fuel is a refined mineral spirits and may have 0-30% by volume mixed isomers of primary amyl alcohol blended therewith. A biocide is added to the mineral spirits.
