The Fuel Fund committee raised diesel by 0.70 baht/litre and benzine/gasohol by 0.80 baht/litre, effective 5am on 9 September 2026. PTT now sells standard diesel at 39.84 baht and gasohol 95 at 39.09 baht; premium grades are unchanged. Prices exclude the Bangkok local tax. Fleets, delivery vehicles and any fuel-linked pricing should be updated for tomorrow; premium fuels stayed flat, so they are the only grade not affected.
