Biodiesel is an alternative fuel of petroleum and has an effect on reducing smoke because that contains oxygen itself. This study shows the results on the durability of diesel engine with 4% biodiesel and WDP 1% as an alternative fuel during 110 hours. Engine dynamometer testing was complete at regularly scheduled intervals to monitor the engine performance an exhaust emissions. Through this experimental result, there was no clogging of the nozzle tip, and there was not carbon deposit on the injector tip. And, there was no unusual deterioration of the engine, or any unusual change in exhaust emission from using the blending fuel.
