Just a basic oil pan, something like
this one but maybe a little wider.
I have some leftover 5 gallon diesel gas cans and I dump the waste in there or in the original oil container.
Oreilly's does recycling here about about one out of five times they'll bitch about the diesel cans not being
approved, but they haven't outright refused me yet.
Good topside oil extractors actually work very well and get almost everything. I used one for my lower
vehicles and tested it by pulling the drain plug after the extraction and got almost nothing more to drain.
Now everything I have is tall enough to work on without any jacking and I just drain the old fashioned
way.
