Again, one of those things I should've bought 15 years ago. I just didn't know these even exist. This is the second most exited I've even been about a bucket only narrowly topped by the time I found two for free.
Life hack I figured out, impromptu bucket, for oil changes and draining fluids. Get a cardboard box that fits and line it with a garbage bag. Drain oil into bag. Tie up up bag and put box and bag into another bag for transport. Or you can cut the corner of full bag to drain into a jug with out making a mess or funnels. Hell got no funnel? Pour the clean oil into a clean bag and cut the corner of and fill engine.
