Oil Cleaning

I want to find out how to clean oil perfectly so it run's nicely in the school bus. I'm also going to research on how to make biodiesel faster and easier. Making biodiesel faster can help you go longer distance's. Also it can maybe be fast enough to make while your on a running bus and you could keep filling up the bus. This can help also by running a bus faster. If we can make biodiesel fast enough you can make a lot of biodiesel for multiple cars in just one day!
