You could just "bury it and don't burn it". The US already has a Strategic Petroleum Reserve. Assuming that you can recycle something close enough to the original petroleum, you could even process the recycled fuel into durable petroleum products instead of consumable ones (lubricants, plastics, etc.)

Or you could sell it to SpaceX and have them ship it all to Mars, so someone can use it to fuel their Mars rovers and terraform Mars.
