"Black gold" or "Texas tea" (3)
I believe the answer is:
oil
I believe this is a double definition.
'black gold' is the first definition.
(I've seen this in another clue)
'texas tea' is the second definition.
(I've seen this in another clue)
(Other definitions for oil that I've seen before include "Greasy liquid" , "Anoint" , "Liquid fuel" , "What can be extracted" , "Type of fuel" .)
