Just murder the sea pickles and get so much oil that America will want to know your location

For early game .. just tame Dung Beetles… at least 2 or 3 is enough… put in close area… give dino poop and some spoiled meat… make them wandering… and u will get oil.. at least 4 and also get fertilizer from poop that u give just know… save ur time and can gather oil to make jerky meat… u will get ton of fertilizer and not need to make fertilizer bin…

You can find oil nodes in the water or you can find a lot in an cold biome, if you have a cryopoded anky and an argentavis you can get a massive amount, just make sure you have some medical brews, otter, fur armor or something else that keeps you warm. I almost died because I only had a fur chest piece, scuba leggings and chitin hat, gloves, and boots and forgot to have medical brews on me.

Kill basilosaurus= infinite oil

Everyone needs oil for late-mid-game, so make yourself some fur armor and go to the snowy areas, there is usually alot of oil rocks on the beaches. Use a metal pickaxe to harvest oil.

Dung beetles make some oil of ya give them poop.

Tame beetle+poop=oil

Sea grass rocks give oil watch out for Megalodon and bassoSauris

P.s I don’t know how to spell good

I think basliosaur actually drop oil naturally if you take it, not sure tough.

Go to rag ship at vb and kill the sea demons and you will be liberated by america

In the south west part of herbibore island there's a lot of trilobites, you can go down there with a spino and you will get chitin, oil, and pearls, is not the most efficent way but is the safest
