Oil

Oil is a dark liquid found in pools around the world. Its primary use is to be refined into fuel to power combustion engines. One must use a pump and waterproof pipes or a bucket to transport it.

Oil Spawns
Finding Oil can be difficult due to its rarity. It comes in the form of small, medium and large oil deposits. 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 which 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.

Medium deposits contain between 100 and 1000 buckets of oil, large deposits between 2 000 and 17 000 buckets.

Extracting the Oil
Once one finds oil, one may use a bucket to pick it up but it is recommended to use a pump for medium and larger deposits, which is made from a tank placed on a mining well. Tanks are made by placing 8 glass in a pattern like a furnace. From the pump one needs to run waterproof pipes to a tank, refinery or combustion engine. Combustion engines may be run using the oil, however this is very inefficent and it should be refined into fuel first.

Refining Oil
To refine oil into fuel, it must be run through a refinery. This must be powered by an engine or conductive pipes. From the refinery, fuel may be placed into storage in a tank using waterproof pipes.
