I've never shaken an oil bottle but I do pour out every last drop. It's more of a waste not/want not deal plus I try to be as environmentally conscientious as possible while still being a gear head...don't want to put motor oil in the recycle bin, just plastic. FWIW, after it seems like the bottle is empty, I leave it on its small side for a while and get another pour out of it.

I did two oil changes yesterday and did not notice anything different looking about the last few drops of oil coming out. One change was Castrol synthetic and one was NAPA cheap conventional oil. Both 5w30.
