NAKHON PHANOM, Thailand The people of Nakhon Phanom province have successfully used oil extracted from a local tree as an alternative fuel for farm machinery, and it is three times more efficient than diesel, the National News Bureau of Thailand (NNT) reported.

The chairman of Phiman Tambon Administration Organisation in Nakhon Phanom's Na Kae district, Bancha Srichaluang, said his organisation tested the oil extracted from hairy-leafed apitong trees (Dipterocarpus alatus) by using it on motorised ploughs, farm tractors, and pumps two years ago.

The experiment began with an equal mixture of the extracted oil and diesel. The diesel content was gradually reduced and completely omitted in the end.

The engines worked normally and no problems were found.

Banchai said past use showed that a mechanised plough ran for three hours on one litre of this alternative fuel, compared with one hour on diesel.
