Wherever the source, Biodiesel is vegetable oil that’s been thru a process called transesterification. That means they’ve taken the glycerin out and replaced with alcohol –making a thinner fluid that’ll pass thru a Diesel engine’s fuel injectors. It’s a pretty nifty hack. That process is what separates biodiesel from waste vegetable oil (greasel) or vegetable oil conversions, which require heating the fuel to make it thin enough to pass thru the engine.
