An oil barrel is a type of Barrel found in DK: Jungle Climber, used to fuel Funky Kong's Biplane Barrel. The Kongs need to find all of them on a regular island and take them to Funky Kong in order to use them. When enough are collected, Funky Kong can fuel his Biplane Barrel and take the Kongs to a smaller version of the island they are on to play a minigame.
The oil barrels seem to resemble oil drums, but with an image of a flame on the front.
