Motor oil related failures not caused by running the oil low enough that the pickup sucks air simply don't happen.
As many have noted, loss of coolant kills more engines than any other single cause, maybe all other causes combined.
Most newer cars lack coolant temperature gauges, not that the average driver would pay any attention to a gauge anyway.
A gauge can save your bacon if you pay attention, though.
When the coolant temperature light illuminates, it means shut down now, not ten miles from now.
Do that and you might just save the engine. Keep on driving and you're probably looking at major and maybe economically unfeasible work to return the engine to service.
