This ^^^^^^^^^^
I change the oil on all three of my vehicles at the same time. So I have a big 5 gallon plastic jug that gets pretty full by the time I am done. (18 quarts total for all 3 vehicles). After I'm finished I take it to my local Auto Zone, and dump it into their big tank in the back. I don't like keeping used oil in my garage for any length of time for fear of any leaks.
