Thailand's fuel consumption in May 2026 fell 4.2% year-on-year to 148.39 million liters/day, with declines across most fuel types (gasoline, diesel, jet, LPG, NGV) reflecting softer economic activity and low tourism season. E20 (ethanol blend) grew 27% to 6.45 million liters/day due to government biofuel promotion pricing incentives. Fuel imports surged 25.7% amid Middle East tensions, prompting diversification toward Far Eastern suppliers.
