INA (the Croatian oil and gas group INA-Industrija nafte d.d.) operates the biggest gas station network in Croatia, but you can also find fuel stations owned by Lukoil, OMV or Crodux. You will also be able to stumble upon some floating Flash gas stations, found in five places in Croatia. These gas stations are constructed on a floating platform rather than on the coast. The waiting times are generally short at the filling stations. On Fridays, though, things are different near the large charter marinas. Long queues are then usual with correspondingly long waiting times.
