Bangkok: Fuel consumption in Thailand experienced a decline during the first nine months of 2025, with average daily usage reaching 153.95 million liters, marking a 0.7 percent decrease compared to the same period last year.
According to Thai News Agency, this contraction was primarily driven by reductions in diesel and certain gasohol types, alongside the rising adoption of electric vehicles.
Mr. Sarawut Kaewtatip, Director-General of the Department of Energy Business, reported that diesel consumption decreased by 2.4 percent, attributed to a slowdown in the Thai economy affecting the agricultural and industrial sectors. This slowdown contributed to declines in trade and freight transport, aligning with a 1.09 percent contraction in the Industrial Production Index from January to August 2025. Meanwhile, the consumption of Gasohol 91, E20, and gasoline declined due to the expansion of electric vehicles, which now account for 7.0 percent of passenger cars with no more than seven seats.
Gasohol 95, however, saw a notable increase of 19.49 percent, driven by a reduced price difference with Gasohol 91. Jet fuel consumption rose by 8.4 percent, supported by a 1.54 percent increase in visitor numbers and expanded air cargo services. The average number of flights during the period increased by 6.05 percent year-on-year.
The report highlighted a 5.1 percent decrease in average LPG consumption, primarily due to reduced petrochemical and transportation demand. Conversely, household and industrial LPG consumption saw growth. NGV consumption saw the largest drop at 16.1 percent, reflecting a decline in registered NGV vehicles and potential closures of service stations.
Fuel oil imports also faced a 1.9 percent decrease, while crude oil imports slightly increased by 0.9 percent. The decline in refined oil imports, including basic gasoline and diesel, contributed to this overall reduction in import activity.
PTT has introduced measures to support the NGV sector, including a price reduction for general vehicles effective from mid-October to mid-November 2025, as part of efforts to stabilize the market amidst these changes.
