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

(Island, Mobile) I tend to get my oil from oily rocks up in the north, snowy, area on the very west side where there are icy islands in the water. The oily rocks are all over the icy islands! Hope this was helpful :)

to get oil over time, tame a dung beetle and put poop in its inventory. it'll turn it into oil as well as compost, and you'll get better results depending on the size of the poop.

You will get enough of this from oily rocks inside the ocean,get yourself a itchy and dive down and be careful about daddy megaladon

To make gasoline, put oil and hide into a forge

There are Quite a bit of oil veins on Fjordur, also the oil fields in the volcano island has a lot of oil rocks, otherwise look in ocean or get a Tuso. Up if helpful!

America wants to know your location.
