Free simple trick:
When I'm servicing any of the 8 family vehicles, I always drain as much as possible while I'm adding oil (within reason), then I put the lid back on and set them on the floor in my garage in a corner upside down, with the bottom of the jug leaning against the wall. It's literally known as my "oil wall" haha. I'll leave them there a minimum of a week, sometimes a month, until someone needs topped off or I condense them into my leftover 5qt bottles. I always keep them separated, and never waste any. It all adds up, and eventually I get a free quart here and there. When I'm done and the bottles are truly empty, they're dry enough to actually be accepted for recycling (although my 5qt jugs usually aren't, they end up being reused to transport used oil to be recycled, and end up nasty and have to be trashed). Either way, less waste.
