Thailand's government and private sector are launching a coordinated push to boost E20 ethanol fuel adoption, with 13 automakers, 5 motorcycle brands, and 7 oil companies confirming compatibility and safety. Current consumption is only 5.88 million liters/day (18% of gasoline-group fuel), despite 4+ million cars and ~80% of motorcycles capable of using it. Main barriers are consumer confusion about vehicle compatibility and incorrect beliefs about engine damage. Thailand has 28 ethanol plants with 7 million liters/day capacity and can support 3-4 million additional liters/day. Government and oil distributors plan awareness campaigns and promotional incentives to drive adoption, strengthening energy security and supporting domestic agriculture.
