That residual film is good for maybe a faction of a min. until oil pressure builds up. He started it and tried to drive it back up the ramps, which is way too long to be without both the lubrication and cooling of the oil as the engine was now under a load. Add in that the engine started to make ugly noises, and the prognosis in not good.......

Debatable. Modern automotive lubricants are designed for very high temp and are thick (effective). You can test/rub two metal parts together for quite a long time! The problem here is the owner had "old oil". Old oil can run-off quite quickly leaving practically nothing to protect metal surfaces.

When load and rpm hits, heats immediately burns off the ineffective oil :/
