Biodiesel cars can run on plain filtered coconut oil

You can run biodiesel engines on filtered coconut oil!

Vanuatan entrepreneur Tony Deamer has adapted his fleet of rental cars to run on coconut oil, a plentiful local commodity. Unlike with many biofuels, coconut oil doens't need to be transesterized – mixed with sodium hydroxide and alcohol to change its chemical composition – to run in a diesel engine. Filtered and warmed to temperatures about 25C, coconut oil is a better than satisfactory substitute for "mineral diesel" – it burns more slowly, which produces more even pressure on engine pistons, reducing engine wear, and lubricates the engine more effectively. Deamer runs most of his vehicles on a mixture of 85% coconut oil and 15% kerosene, but has demonstrated that modified diesel engines run filtered coconut oil quite happily.
