Motorists should prepare for higher costs at the pump as domestic refined oil prices are slated for a fresh round of adjustments at 24:00 tomorrow (August 28). Projections indicate a substantial price hike, with filling up a standard tank potentially costing more than 14 yuan extra.

Driven by sustained gains in international crude oil benchmarks, expectations for an upward adjustment have steadily climbed, now firmly placing the change within a significant increase bracket. Should current market momentum persist, this adjustment will mark the 11th rise of the year for both 92-octane and 95-octane gasoline.

According to institutional forecasts, domestic gasoline and diesel prices are expected to rise by 360 yuan per tonne. Translated to retail levels, this equates to an increase of approximately 0.28 to 0.30 yuan per litre. Consequently, motorists filling a 50-litre tank can anticipate an additional expense of 14 to 15 yuan.

Following the price cut on August 14, the 2026 calendar has now seen a total of 16 adjustments to oil prices. This year's tally includes 1 instance where adjustments were suspended, 10 increases, and 5 decreases. However, despite these fluctuations, the net effect for 2026 remains a cumulative rise of 1,345 yuan per tonne for gasoline and 1,295 yuan per tonne for diesel, translating to an overall increase of more than 1.03 yuan per litre for refined fuel prices.
