Yekaterinburg sits where the European and Siberian routes meet, and its ring road (ЕКАД) is lined with forecourts. Башнефть is visible here in a way it is not further west, and СУГ (LPG) is unusually widely sold. The networks you will see most are Газпромнефть (48), ЛУКОЙЛ (43), Башнефть (18), GGroup (6) and Нягань-Газ (5).
LPG is well covered in Yekaterinburg: 73 of the 245 fuel stations carry it, so an autogas car is easy to run here. See Yekaterinburg on the map →
