People don't add oil to their cars very often now, but 25 years ago I was at a busy gas station and found enough discarded one quart oil containers to nicely lube my chain. Most drivers are too impatient to let all the oil drain out. Squirting water out of a plastic bidon works poorly to clean, if you can do it multiple times it gets "okay", then lube right away; you will be better off than total neglect.
