Troubled, let me pour oil? (9)

Ross

I believe the answer is:

petroleum

'oil?' is the definition.
(petroleum is a kind of oil)

'troubled let me pour' is the wordplay.
'troubled' indicates anagramming the letters.
'let'+'me'+'pour'='letmepour'
'letmepour' with letters rearranged gives 'PETROLEUM'.

(Other definitions for petroleum that I've seen before include "Fuel oil" , "Hydrocarbon oil" , "Crude oil" , "Oil well product" , "It helps in getting things moving" .)

I've seen this clue in The Telegraph.
