Heavy Oil

Heavy oil is the most common refined result out of Crude Oil in the Oil Refinery. Its appearance is very similar to crude oil itself, only difference is that it is slightly brighter, similar to coal.

Obtention
Primarily obtained from the Oil Refinery, every 1,000mb of Crude Oil results in 500mb of Heavy Oil.

Coal can be liquefied into it in the Chemical Plant, but you need at least 600mb of Heavy Oil to start it.

Uses
It isn't particularly useful in itself, it can be solidified, but that's a waste really.

It must be refined further in the Chemical Plant.

Every 1,000mb of Heavy Oil processed results in 300mb of Bitumen and 700mb of Industrial Oil.
