A combustible solid fuel source in the form of a log is formed from a base material of a cellulosic or fibrous organic material which is compressed in a screw press up to 20,000 pounds to a density in the range 50 to 85 lbs/cu ft. The log is cut to length and partly immersed in a bath of a combustible vegetable oil which absorbed into the base material as it slightly expands such that the content of oil is less than 50% by weight and generally of the order of 30% where the log is dry to the touch and the oil is entirely contained without the need for an external covering of wax or the like. The base material is selected from lumber, agricultural waste or animal waste to contain fibers such that the content of ash when the source has been fully combusted is generally less than 2% by weight with very little contaminants.
