The current research is aimed to introduces new formulations of additives to stabilise 20% water mixed emulsion fuel made of commercial diesel and water. various formulations of emulsifiers were prepared in a lab scale and their efficiency were tested in water-in-diesel (w/d) emulsions, the formulated emulsifiers were designated as sample A (SA), sample B(SB), sample C (SC) and sample D (SD) sample E (SE) and sample F (SF). Stabilty study was conducted by obseving (visually)  and recording the changes as well as phases separation. Stbility assessment was conducted in two stages, in the first stage, the amount of water or oil separation from the freshly prepared emulsion were recorded for an hour at 10 minutes interval, if there is any water or oil separation within this 10 minutes then emulsion is considered unstable or failed to pass to the second stage. In the second stage, water separation and pictures for visual obsevation were taken in a daily basis for one week. The optimal and most stable emulsion fuels were observed with samples C, D and F, which gave zero separation of phaces within one week. Followed by samples B and E whom each gave 3.8% oil separation, then sample A which gave 5% water separation. Based on this results, authors have no single doubt to say that, the new formulation C,D and F surfactant are very effective stabilizers for emulsion fuel and performed far better than their commercial counterpart.
