The theft occurred between Saturday 6th of April and Saturday the 20th of April.
According to Garda Mick Duffy it is believed that the culprits spent a "considerable" amount of time at the scene to remove such a large quantity of oil.
Gardaí are appealing to anyone who noticed any suspicious activity or who observed a vehicle parked nearby for a length period of time to get in touch.
Speaking to Northern Sound, Garda Duffy highlighted that any information, big or small, can go a long way in helping investigating officers with their enquiries.
"Something that you may feel is insignificant could in fact tie in with other elements of an investigation. If there is anything at all that you feel may benefit the investigation please get in touch."
