Fuel talk of avoiding loud row (8)
I believe the answer is:
gasoline
'fuel' is the definition.
(gasoline is a kind of fuel)
'talk of avoiding loud row' is the wordplay.
'talk' becomes 'gas' (I've seen this before).
'avoiding' is a deletion indicator.
'loud' becomes 'f' (A musical term).
'row' becomes 'line' (I've seen this before**).
'of' with 'f' taken away is 'o'.
'gas'+'o'+'line'='GASOLINE'
(Other definitions for gasoline that I've seen before include "Sole gain (anag.); petrol" , "US petrol" , "American petrol in full" , "US fuel" , "Fossil fuel" .)
