Therefore, monitoring the quality of commercialised fuel is a very important issue. This work presents and discusses the influence of the addition of different proportions of n-paraffin, mainly n-hexane, kerosene and diesel oil on the distillation profile and octane number of automotive gasoline. The results show that it is possible to add non-allowed substances while keeping the automotive gasoline within specification limits. This means that much research should be undertaken in order to establish methodologies that can allow inference of the presence of such substances through physicochemical analyses, even at low concentrations.
