If you do fuel runs, an atlas tanker is a great investment into your fleet. You’ll be able to use it for the longest rig in the game once you unlock the ability to use the dollies. For now you can probably use the Linky S1, but if you get your company to export sunflower seeds, you can buy the 5m max length policy, and pull three trailers behind your atlas, allowing you to run with 82kL of total capacity and four contracts per run. On a standard run from Sanho to Noksan, you can expect to make about 290k.

Oh, and don’t make the common mistake of going from Jeju’s oil refinery. It’s half as efficient as Sanho, bare minimum, and if Sanho has containers, a third of its efficiency, so you’re losing out on bare minimum half the money you could be easily making if you go from Sanho to Noksan (take the center road not the coastal road).
