Kaliningrad is a Russian exclave with its own fuel economy: Сургутнефтегаз and the local Балтнефть network are more visible than the majors that dominate elsewhere, and the region is small enough to cross on one tank. The networks you will see most are Сургутнефтегаз (16), ЛУКОЙЛ (13), Балтнефть (10), Роснефть (5) and Teboil (5).
Prices in Kaliningrad appear when a driver reports one or an official feed carries it, always with the time it was recorded, so you can judge for yourself whether it is still true. See Kaliningrad on the map →
