Ukrainian fuel station networks adjusted their retail fuel prices on September 18, 2026, and this time the changes went in different directions: some grades became more expensive, while one type of fuel, conversely, got cheaper. According to RBK-Ukraine monitoring, the OKKO network raised the price of two gasoline grades, while Ukrnafta lowered the price of liquefied gas. The situation in the market is also noted by other publications, pointing out that diesel fuel has come close to the psychological mark of 100 hryvnias per liter. Photos from fuel stations during the same period also show everyday details of the era: a driver is refueling an old Volga (GAZ-24) with a Ukrainian license plate, and at the base of the columns there are sandbags, which have become a familiar attribute of fuel stations in wartime conditions.
What got more expensive at OKKO
At OKKO, the increase affected precisely the gasoline grades. The premium Pulls 95 gasoline rose by 1 hryvnia per liter and now costs 95.90 UAH/l, while the standard A-95 Euro — by 92.90 UAH/l (also +1 UAH). Meanwhile, the price of diesel fuel and autogas at this network remained unchanged, meaning the rate revision at OKKO was targeted and concerned only two gasoline grades.
Ukrnafta cuts the price of autogas
In the opposite direction acted the Ukrnafta network, which lowered the price of liquefied gas by 1.70 UAH — to 41.20 UAH/l. This is the only notable price cut among the major networks on the day of monitoring. Prices for other types of fuel at the company's stations remained at the previous day's level, so overall the balance of changes at Ukrnafta looks neutral thanks to the targeted cut on gas.
Diesel holds the 100-hryvnia line
The main marker of the day was the diesel price. At OKKO, WOG and SOCAR stations, as well as at Ukrnafta's premium diesel, the fuel came close to the round mark and holds at 99.90 UAH/l. In effect, diesel has "stopped" just under 100 hryvnias and holds this line, which the RBK-Ukraine editorial team describes as a "critical threshold" for consumers and carriers.
WOG and SOCAR: prices frozen
Two other major networks — WOG and SOCAR — as of September 18 kept fuel prices at the same level compared to September 17, making neither increases nor decreases. Thus, the overall picture of the day turned out mixed: a targeted rise in gasoline at OKKO, a targeted cut in gas at Ukrnafta, and a stagnation of rates at WOG and SOCAR amid overall pressure on diesel, which does not retreat from the 99.90 UAH/l mark.
Contradictory data
Here it is important to honestly examine the discrepancy between the headlines and the details. A number of publications present the news in the key of "fuel stations raised fuel prices again," emphasizing the increase. However, in the breakdown by item this picture is incomplete: at Ukrnafta gas, conversely, got cheaper by 1.70 UAH, while WOG and SOCAR did not change prices at all. In other words, the claim that "prices went up again" is true only for some grades (gasoline at OKKO), while across the full set of items the day was mixed. The difference here is in the emphasis of the presentation, not in the figures themselves: the specific rates (95.90 / 92.90 / 41.20 / 99.90 UAH/l) match across sources.
Context: what lies behind the figures
The mixed dynamics — a rise in gasoline, a cut in gas, a "freeze" in diesel at some networks — reflects the cautious tactics of operators who adjust individual items rather than carry out a mass increase. For a driver, this means that when choosing a fuel station and a type of fuel, a difference of several hryvnias per liter is already noticeable, and diesel, holding at 99.90 UAH/l, becomes the key indicator of the further market dynamics in September 2026.
