Evaluating the Cost-Effectiveness of E20 and B20 Biofuels in Thailand
As energy prices fluctuate, Thai motorists are weighing the cost-efficiency of E20 and B20 biofuels against conventional fuels to manage travel expenses.
Amidst volatile energy prices, Thai motorists are increasingly considering the use of E20 gasohol and B20 diesel as potential cost-saving alternatives. According to a report by Khaosod Online Thailand, the primary debate centers on whether the lower price of these biofuels compensates for potentially lower fuel efficiency per liter. To determine true value, experts suggest comparing the total cost of travel over a fixed distance rather than focusing solely on mileage. As of October 28, 2026, the price difference is notable; for instance, Gasohol 95 was priced at 42.04 baht per liter, while E20 was available at 33.50 baht per liter, representing a difference of 8.54 baht or approximately 20%. Beyond individual savings, the promotion of these biofuels is linked to supporting domestic agricultural raw materials and reducing reliance on imported petroleum. For residents and travelers, understanding these price dynamics is essential for budgeting transportation costs. However, it remains to be confirmed how specific vehicle models perform over long-term usage with these fuel blends and whether the price gap will remain consistent as global market conditions evolve. Motorists are encouraged to check their vehicle's compatibility with these fuel types before switching.
