168F Chinese Diesel with Tachometer running on cooking oil 

Approximately first 90 seconds of the video is a test run of pressure building.
The rest is testing out a mixture of diesel fuel and popcorn cooking oil. To put it this way it smelled like popcorn. Straight diesel made the engine loud. When i mixed it with the cooking oil, it quiet down the engine.
Thank you for watching this video. Next, I'm trying for straight popcorn oil
