Fuel: one reeks after spillage (8)

Ross

I believe the answer is:

kerosene

I'm a little stuck... Click here to teach me more about this clue!

'fuel' is the definition.
(I know that kerosene is a type of fuel)

'one reeks after spillage' is the wordplay.
'one reeks' anagrams to 'KEROSENE'.
However, I am not sure how this is indicated.

Can you help me to learn more?

(Other definitions for kerosene that I've seen before include "Combustible" , "Paraffin oil (E, not I)" , "Oil used as fuel in lamps and heaters" , "Sore knee (anag.)" , "No seeker for American fuel oil" .)

I've seen this clue in The Telegraph.
