Oil is a critical resource for advanced crafting in ARK: Survival Ascended. Found underwater, in desert biomes, and from oil-producing creatures like the Dung Beetle.
Node yields assume the base harvest HP from game data (e.g. 1000 for Redwood trees, 620 for Metal nodes). In-game, trees and rocks with bAllowHarvestHealthScalinghave per-instance HP that varies with the node's size, so actual yields per node will vary. The values shown represent the average.
These creatures reduce Oil weight when carried in their inventory.
The Diplocaulus is the best Oil farmer with a 32.5x gather multiplier from game data. The Rock Elemental is the runner-up with 9x.
The following creatures reduce Oil weight when carried: Dunkleosteus (-50%). This means they can carry more Oil before becoming encumbered.
