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.
Technician reported that confusion over oil drums caused several aircraft to be serviced with waste oil.
