The Ukrainian fuel market entered September 2026 with a new round of price reviews. As of Friday, September 4, major gas station chains once again adjusted their price lists: some operators raised the cost of gasoline and diesel, others kept their previous levels, while the state-owned Ukrnafta went against the market and cut the price of its branded gasoline. This mixed dynamic makes the current picture one of the most contradictory in recent times and underscores that there is no longer a single price trend in the market.

What changed at gas stations on September 4

According to RBC-Ukraine data, as of Friday, September 4, prices for all types of gasoline and diesel fuel rose again at some stations. The adjustments affected two major players — the OKKO and SOCAR networks. Both operators raised the cost of gasoline and diesel by 1.00 UAH/l. As a result, refueling a car at these networks became exactly one hryvnia per litre more expensive for each fuel type, which, when translated to a full tank of an average crossover, adds roughly 30–40 hryvnias to the bill.

Prices by network: OKKO, SOCAR and WOG's stability

At the SOCAR network, after the increase, premium diesel fuel NANO Extro reached 99.90 UAH per litre — effectively on the edge of the psychological 100-hryvnia mark. The OKKO network also raised all types of gasoline and diesel by 1.00 UAH/l. Meanwhile, at WOG stations the price tags on Friday remained at the previous day's level — the operator made no adjustments. This means that the difference in the cost of the same fuel type between networks continues to persist, and choosing a specific gas station becomes a noticeable factor in savings for the driver.

Ukrnafta against the market: a promotional cut

The state company Ukrnafta acted in the opposite direction. As part of a promotion, it cut the price of its branded gasoline by 3.00 UAH/l, effectively bringing it to the same cost as regular A-95 gasoline. The final price came to 79.90 UAH/l. This decision stands out against the backdrop of general increases and can be seen as a tool for retaining market share and supporting demand amid price hikes by private operators.

Contradictory data

The overall picture on September 4 contains a clear inconsistency in the dynamics. On the one hand, the private networks OKKO and SOCAR record a price increase of 1.00 UAH/l across all fuel types, with diesel at SOCAR approaching 100 UAH/l. On the other hand, WOG holds its previous levels unchanged, while Ukrnafta, conversely, cuts the price of its branded gasoline by 3.00 UAH/l to 79.90 UAH/l. In other words, on the same day three scenarios are simultaneously in play in the market — growth, stability and a decrease. The differences in figures between networks are not a data error but reflect the operators' differing pricing policies; however, for the consumer this creates a contradictory perception of an "overall" price level, which in fact no longer exists as a single value.

Context: dynamics since the end of August

The current adjustments continue a trend that emerged as far back as the end of August, when prices for gasoline and gas at Ukrainian gas stations were also rising. The repeated increase at the start of September points to sustained pressure on retail fuel prices. For car owners this means that refueling at popular networks is becoming more expensive, and the most advantageous option on September 4 remains Ukrnafta's promotional offer of gasoline at 79.90 UAH/l, or the stable WOG price tags that were not subject to today's hike.
