Gas coil (4)
I believe the answer is:
wind
This clue is a double definition.
'gas' is the first definition.
(thesaurus)
'coil' is the second definition.
(I know that coil is a more specific form of the action the wind)
(Other definitions for wind that I've seen before include "Twist, turn; breeze" , "Air current; twist" , "section of orchestra" , "Move on a twisting path" , "Twist or turn (in course)" .)
