It's a common thing to happen, I suppose. Mother dearest did it once, but (thankfully!) noticed within 6 miles when large quantities of smoke started to be pumped into the car through the air-vents.
Evidently the old Vauxhall garage down the road had a lady drive in as the car was "acting funny" for nearly three months. Three months since she last checked up the oil... Evidently there was *no* oil left and it needed a new engine. Not sure how much of that is true, though.
