The use of poor quality heavy fuel oil diesel (HFO) in diesel engines has increased considerably over the last decade. This increase has been driven purely from the immediate financial benefits associated with the price of poor quality heavy fuels. The notion of ’if it burns, use it' has led to catastrophic and irreversible damages to many engine components. Compounding the former dilemma is the inadequate knowledge of some operators with respect to the qualities of HFOs and their effects on diesel engines. Secondly, some educational institutions responsible for educating these operators have not developed the appropriate courses to address this issue. It is than evident that there is a need to develop a practical and comprehensive discourse on this subject. The essence of this discourse will be to provide the would be operator and the practising operator with the knowledge necessary to efficiently manage the use of HFOs in diesel engine plants.
