In this work Box – Behnken method which is generated by MINITAB (version 17) statistical analysis software was used to study the factors affecting on the extraction yield of base oils from used lube oils. A mixture of solvents contains Butanol and MethylEthyl Ketone (MEK) were used with weight ratio of 1:1 and KOH (2gm / Kg solvent) were added to enhance extraction rate and the solvent to used oil ratio was 6:1. The effect of temperature, mixing time, and mixing speed were studied. It was found that the temperature has a largest effect and The extraction yield increases with increasing the temperature up to 50°C. On the other hand increasing mixing time decreases the extraction yield this is may be due to the rich 1-butanol and MEK solvent mixture will dissolve base oil components containing some contaminants. Mathematical model equations were derived for the percent of extraction yield by using the experimental data and the mathematical software package MINITAB (version 17). Predicted values were found to be in good agreement with the experimental values. An optimization was carried out to detect the optimum conditions that produce an extraction yield of 96%.
