Narrative:

Last week I was informed that the oil drum was running low. After asking stores personnel more than once over the span of a couple of days to bring new barrels over from our remote storage facility; I went out with [name] near our loading docks where new barrels are often stored alongside waste barrels before they are moved over to find a barrel we could use. We found a barrel that appeared to be unused and we brought it into the hangar. I was informed that a bowser was filled with waste oil but that the mechanics who identified it thought that all that was serviced was an idg; which was flushed and ops checked good and then the bowser was put out of service and the barrel removed. ZZZ identified an aircraft that was serviced with waste oil. I feel that the source of this waste oil may have been me moving the barrel from outside; and as a consequence several aircraft may have been serviced with waste oil. The crew chiefs then worked with maintenance control to identify all aircraft that may have been affected. I will say I failed to follow procedures as I did not verify the barrel to see if it had a serviceable pmi tag.stores acting upon requests when they are made could have eliminated this issue as well as them not storing waste and new oil next to each other. I also should have verified the pmi tag and issued it to the floor when moving the barrel.
