I typically leave quart or five-quart jugs sitting in the funnel until they start dripping slowly, which takes only a minute or two, before I consider them empty enough to toss out. I feel like most people do the same thing.
Two questions!
1. How much residual oil do you think remains in a 5-quart jug of oil once it is "emptied", after using it to fill your sump?
-----Note: this obviously excludes partial use of bottles and jugs and specifically pertains to emptied containers
2. When you're draining a bottle or jug into your engine during an oil change, when do you consider a jug or bottle to be empty (e.g., steady stream stops and you toss it; dripping slows to X amount/second before tossing it; or you leave the bottle/jug sitting on the funnel or filler neck for hours to get every last drop of oil from the bottle/jug, etc.)?
What's the point of this thread? Well, I'll tell you:
When our hobby shop was open AND accepting used quart bottles and jugs, they'd request that we place them upside-down, with caps-off, in a rack above a collection pan so that all of the residual oil would drain out before they disposed of the bottles/jugs.
At any given time there seemed to be a significant amount of drained oil in the pan, which they drained at least daily, or as often as needed (if the rack was full), as waste oil. If I had to guess, I'd say that there was routinely a quart or more in the bottom of the pan every time I went in to do work on my car or change the oil. I'd love to see a "VOA" of that stuff!
