Just saw this today in the news:

TAIPEI, Taiwan -- The Energy Bureau (E under the Ministry of Economic Affairs (MOEA) announced yesterday that all fossil diesel in Taiwan will be mixed with biodiesel derived from waste cooking oil starting on July 15.


Is this safe for the engine...? So starting in a few weeks, I'll be filling up with diesel mixed with stuff from recycled cooking oil.... it's pretty environmental yeah for sure but...

Here's the link as well:
