Fuel Station is a special production building added in Bright Harvest DLC. It consumes 1 ton of oil and produces 1 ton of fuel every 15 seconds, thus producing 4 tons of fuel every minute.
It need railway connection to the oil harbour, from which the trains will supply the fuel station with oil.
Fuel station delivers fuel to all tractor barns in its influence range, based on the road distance. Each tractor barn consumes 1 ton of fuel every 5 minutes, so 1 fuel station can supply up to 20 crop farms.
The productivity of fuel stations can't be changed by adjusting working conditions.
