I wonder where all those food carts throw their used oil, probably into the klong whilst no one is looking. I used SVO a few times with no probs and it was used oil too from a chinese food manufacturer. I didn't bother with the whole bio process, just filtered it, mixed with white spirits and a few drops of acetone.
