Re: Low Oil Warning Light & Engine damage
If he drove it hard with the light on for some time, the engine could now be toast from overheating and lack of lubrication. You said it would not turn over when he tried to restart; you mean the starter would not crank, or the engine would not start ? I assume you also checked the dipstick after the engine is hot, to make sure you did not overfill the crankcase after adding the 2 quarts .... that can also cause rough running.
