A crucible furnace was designed and constructed from locally sourced materials and fired using spent engine oil (SEO). hile combustion of SEO was effective during evaluation which was done with the melting of AluminiumSilicon alloy scrap metals in the crucible furnace, its continuous availability cannot be guaranteed. Experimental analysis was carried out with SEO mixed in proportions 1 : 5, 1 : 2, 1 : 1, 2 : 1 and 5 : 1 with diesel and kerosene with a aim to reduce cost. The fuel samples were comparable with the conventional fuels in terms of the physicochemical properties evaluated. The cost of the admixed fuel reduced as the quantity of SEO in the mixture was increased. Similarly, the least amount of time taken to combust 450 ml was achieved with the fuel mixture with the least SEO ratio. Maximum temperature build up of 190 oC was achieved when the 450 ml fuel sample had kerosene as two third of its content, and maximum of 124 oC when equal proportion of diesel was added to SEO. Moreover, for melting purposes, admixtures with diesel will be recommended because of its higher calorific content that is burnt slowly. This is suitable for the latent heat required in melting.
