As a result,viscosity increased as well with increased coconut oil in blends.Other properties of blended fuels varied according to their physic-ochemical properties. However, additional research is suggested tosubstantiate these results. The above findings further suggested aneed to establish a commonly accepted fuel standard as previouslysuggested (Özener et al., 2014). In the absence of a fuel standard,further engine emissions and performance work will be of limitedvalue
