I was recently coming back from Chachoengsao and on the left hand side of the highway, just before Minburi I noticed that Bangjark was selling B5 Bio Diesel. I stopped and filled up. It was 50 satang cheaper than normal diesel. B5 is a 5% blend of Bio Diesel and normal diesel. I asked if they had other stations that sell B5 and the attendant advised that there are only 2 locations in Bangkok. That particular station near Minburi and another on Rama 2 road.

Does anyone here know of any other locations that sell Bio Diesel in Thailand?

Does P.T.T. and the other large oil companies have biodiesel?
