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 :)

Tek creatures can drop oil, electronics, AND metal. Tame a breeding pair of Tek parasaurs and kill their babies

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.

To make gasoline, put oil and hide into a forge

America wants to know your location.

if you can’t find a critter that drops oil, i found quite a lot of oil rocks in the northern region (mobile, island map), around the shore. be weary of wolves and argies. rexes too, but typically they’re preoccupied with mammoths or rhinos. hope this helped!

Tame a basilsaurus just leave it and it will produce oil

Gachas produce so much oil I’m surprised that America hasn’t invaded extinction…

Oh wait…
