Lubricant container (6)
I believe the answer is:
oilcan
'lubricant container' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for oilcan that I've seen before include "Vessel for lubricant" , "Lubricator with a long nozzle" , "Vessel for viscous liquid" , "Lubricant applier" , "Lubricant container" .)
