BANGKOK, THAILAND – Major fuel retailers PTT Station and Bangchak significantly reduced diesel and gasohol prices across Thailand from early 11 April 2026.
Price cuts took effect on 11 April
On 10 April 2026 it was reported that PTT Station and Bangchak Petroleum (BCP) would lower fuel prices in several categories. The reductions took effect from 5:00 a.m. on 11 April 2026 at stations nationwide.

Important note on Bangkok taxes
According to the report, the stated prices did not yet include the local maintenance tax for Bangkok. This municipal levy could still be added at the point of sale.
Depending on the exact location within the capital region, additional charges could influence the final pump price. Motorists in the Bangkok area were therefore advised to check local rates when filling up.
