Note a Renault going uphill that stops squeaking
I believe the answer is:
oilcan
'stops squeaking' is the definition.
(I've seen this before)
'note a renault going uphill' is the wordplay.
'note' becomes 'n' (abbreviation).
'renault going' becomes 'clio' (I can't explain this - if you can you should give a lot more credence to this answer).
'uphill' shows that the letters should be reversed in order (in a down clue, letters go up).
'n'+'a'+'clio'='naclio'
'naclio' written backwards gives 'OILCAN'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for oilcan that I've seen before include "item found in the garage" , "Vessel for lubricant" , "stops squeaking" , "Container used in lubricating machinery" , "Lubricant applicator" .)
