OR, Bangchak raise fuel prices by up to 0.75 baht

Fuel prices at PTT Station and Bangchak outlets rose from 5am on Wednesday (September 2, 2026), with most petrol and gasohol products increasing by 0.60 baht per litre.

PTT Oil and Retail Business Public Company Limited (OR) and Bangchak Corporation Public Company Limited (BCP) announced the new retail rates.

Their general notice put the increases for regular diesel and diesel B20 at 0.75 baht per litre, while other diesel prices were unchanged. 

Bangchak’s itemised schedule, however, listed Hi Diesel S as rising by 0.60 baht per litre to 39.17 baht, rather than the 0.75-baht increase stated for regular diesel in the general announcement.

The listed prices apply to retail sales in Bangkok and exclude local maintenance tax.
