Im surprised theres no Tips on this item, but I’ll state the obvious.

The Oil Pump can be used on oil clusters in Scorrched Earth. These are NOT the same as oily rocks and can only be extracted by Oil pumps.

(They are common in airdrops)!

Not much to say, it's an oil pump. And takes about 20 seconds to generate one oil.

Can be put on top of oil veins.
