The premium gasoline is a main fuel for transportation sector, especially for land transportation that use private and public transportation. In order to reduce the amount of gasoline import that increases year by year, the Government launched bio-ethanol – premium gasoline mix program, a mixture of certain amount of 95% purification bioethanol into premium gasoline. In the 1983, performance testing ofbioethanol vehicles conducted, in 100 cars and 32 motor cycles. The testing result proved that the performance of the car engine was not decreased significantly, but some of the gasoline tank and packing were leaked. Recently, the fuel based ethanol (99.5% purification minimal) are used in the car and other land transportation vehicles. It is also proved that the gasoline – bioethanol mixed will released smaller emission compare with gasoline only, except aldehydes. Considering to the economic evaluation, it is clear that the price of bioethanol (include tax, delivery cost, and benefit) today almost the same level with premium gasoline.
