Fuel runs out just outside of Eccleshall (6)
I believe the answer is:
diesel
'fuel' is the definition.
(diesel fuel is a kind of fuel)
'runs out just outside of eccleshall' is the wordplay.
'runs out just' becomes 'dies' (I can't justify this - if you can you should give a lot more credence to this answer).
'outside of' suggests removing the centre (only letters on the outside of the word).
'eccleshall' with its centre removed is 'el'.
'dies'+'el'='DIESEL'
Can you help me to learn more?
(Other definitions for diesel that I've seen before include "Fuel used by heavy vehicles" , "Engine fuel" , "Lorry fuel" , "Motor fuel" , "See lid, oddly, of the fuel" .)
