Question

What are the down-sides to using coconut oil as an alternative to petrol?

Answer 1

In cool weather it will solidify but you overcome this by adding diesel petrol.

At this stage the only down-side is that it isn't mass produced.

Answer 2

your car will smell funny and coconuts are wasted

Answer 3

I know that the coconut oil solidifies in lower temperatures (about 25 degrees celcius, I think) but it's not a drama because you simply mix the coconut oil with diesel fuel.

It is big in Bougainville and many other pacific islands.
