Crude Oil

Crude oil is the standard oil type in the game, Obsidian Miner. Crude oil lasts for a decent amount how long it is, while giving off a decent brightness of a light.

Crude oil is the raw form of oil in the Obsidian Miner lore. Miners found the ores, and to save money would put it in their lantern to burn off raw. It does not catch fire easily, but does release harmful toxins, so some miners switched to the more expensive industrial oil.

Crude oil was the first oil type introduced into Obsidian Miner back in its on the earliest stages. It wasn't until a bit over a year later until the other two types were added.
