Oil Mining 3D: Petrol Factory

Oil Mining 3D: Petrol Factory lets you build an oil business from a single rig to a network that supplies cars, ships, and planes. Crude sits deep underground, where only drilling rigs can reach it. From there, oil moves by rail to the refinery, gets processed into gasoline, then heads to gas stations where customers pay in cash. As production climbs, your operation grows with it. This idle game keeps the chain moving from extraction to delivery.

How to play?

Place your first rig and pump oil immediately. Upgrade three key stats: passive income, extraction speed, and barrel capacity. Tap the rig to pump faster by hand. Watch the progress bar above the upgrade tabs to see how close you are to unlocking another rig, then spend your cash where it pushes production the most. Once you've stored enough oil, lay down the railroad to ship it to the refinery. After that, open your first gas station, complete missions for rewards, and pick up bonus cash for clearing levels. Keep adding rigs and stations until your supply chain can handle ship and plane refueling.
