Crude oil is a liquid extracted by pumpjacks from oil fields and can be converted to petroleum gas, light oil, and heavy oil by an oil refinery. It can be transported either in pipes, barrels or fluid wagons.

It can also be used as ammo in flamethrower turrets.

Oil fields

Oil fields can be used indefinitely, but the amount they yield will reduce over time. Each oil field has a yield displayed as x%. Each percent is equal to 300 pumpjack cycles. Without speed modules one pumpjack cycle takes one second to complete. An oil field with 80% has between 24000 and 24299 cycles left, as yield does not display decimal places.

While cycles left is greater than 6000 (20% yield) and greater than 20% of the initially available cycles, each pumpjack cycle reduces the number of cycles left by one.

So unless an oil field with less than 20% yield is created by map editor, yield will never drop below 6000 cycles.

The amount of oil a pumpjack extracts per cycle is yield multiplied by 10 (e.g. 115% yield = 1.15, multiplied by 10 = 11.5), and cannot be higher than 1000.
