A tractor engine was fuelled with blends of dewaxed-degummed jatropha oil and diesel up to 50:50 (v/v) ratio. Higher power was obtained with treated oil than raw oil for all fuel blends. The engine operated well up to the blend ratio of 30:70 with treated oil and then there was sudden drop in engine speed under overload conditions. https://www.chiggate.com/maybelline-coverstick-concealer-green-redness-fashion/
