We were on vacation this August, we were stunned by the price of gasoline - 6 Russian rubles higher than in St. Petersburg. You can't fill up first and then pay. Apparently, Russians are not trusted: they are asked to pay for some amount of gasoline, then refuel, and if all the paid gasoline does not fit in the tank, they will refund the money)).
Prices are the same as everywhere else. Fast service. When refueling at other gas stations of other companies, the car starts to slow down, when refueling at the Belarusneft gas station, everything is fine.
