Oil is a dark, viscous fluid that can be found floating in oceans and rivers around the world, from oil geysers or oil pools. Its primary use is to be refined into fuel to power combustion engines. Pumps and waterproof pipes or buckets can be used to transport oil around.

Oil Spawns[]

Finding oil can be difficult due to its rarity. Oil deposits come in small, medium and large sizes:

  • Small oil deposits contain up to 16 buckets of oil and are "common" in the desert biome, having a 3% chance of generating there. Large deserts usually contain several of these.
  • Medium and large deposits consist of an oil bubble where its center is located between depth 20 and 30. They can be spotted from the surface through an oil deposit looking like a regular deposit, except that it can be located on any biome, and contain a chimney going from the actual bubble up to a geyser when reaching the air. The height of the geyser gives some indication of the size of the deposit.

Medium deposits contain between 100 and 1,000 buckets of oil, large deposits between 2,000 and 17,000 buckets.

As well, in Buildcraft v. 3.70+, there are oil fields. They are a separate biome, and have a chance of generating Ocean oil fields, as well as Desert oil fields. Ocean oil fields produce numerous large springs. Deserts hold less oil, but are more common.

Extraction of Oil[]

Once you find oil, you may use a bucket to pick it up, but, it is recommended to use a pump to continuously extract the oil, especially from medium and large deposits. Waterproof pipes must then be connected from the pump to a fluid storage block(e.g. tank, refinery or combustion engine). Combustion engines can run off oil, but the process is very inefficient.

Refining Oil[]

To refine oil into fuel, it must first be piped or transported into a refinery. The refinery must then be powered by an engine or from connected conductive pipes. From the refinery, fuel must be ejected via waterproof pipes before it can be placed into storage in a tank.


Oil is highly flammable and can therefore, catch on fire. Unlike other flammable materials like wood, when oil catches fire from a nearby fire source, it does not disintegrate(i.e. disappear).

  • Oil has similar properties as water and hence, will be able cool lava and allow fishing.
  • A mining well that hits an underground oil bubble will stop drilling.
