Yeah - that happened to me when an incorrectly fitted sump drain plug fell out. My beloved didn’t notice the increasingly urgent warning lights from the car telling her to stop right away - and merrily motored all the way home (a distance of 70 miles)
Astonishingly, the cost was a new drain plug and a refill of all. 100k miles later it’s still running sweetly.
I can only assume that because the car was moving when the disaster occurred all the oil was circulating up in the engine so enough was available to keep it running.
