There are four different types of Vortex depots: oil storage depots, oil drilling sites, refineries, and gas stations. Gas stations are shown in a section of their own below.
Gas stations are commonly equipped with an underground fuel storage tank.
Some of these underground tanks accept cargo deliveries as part of the game's economy.
They are not marked by company logo on the world map, except when they are the destination of an active delivery.
The following table lists all gas stations with a Vortex underground tank accepting deliveries:
Before update 1.51, all gas station unloading points were branded as either Vortex or Gallon Oil in the job market, irrespective of the actual brand of the gas station.
Uniquely, Oklahoma City contains a Vortex depot defined as 'vor_oil_str1'. The prefab is the same as that of the refinery.
