car wont start

My sis was driving her 96 saturn SL and she was at a red light, then the car just stopped on her and it wouldnt start back up. I had came to push the car to the side of the road to see what the problem was. When I tried to start it, I could hear 1 click. All the lights came on, on the dash but it wouldnt start. I tried to give it a jump but that didnt work. I checked the oil and the oil was really low. There was no oil showing up on the dipstick. So I put in about 4 quarts of oil. The car still wouldnt start. So I had it towed. The mechanic said that my sis would need another engine for her car. Would really low oil cause someone to need another engine for a car. My sis had just got a oil change about 2 weeks before this happened. I use to drive her car about 5 years ago and it use to burn a quart between oil changes but what would cause the engine to loose so much oil in about 2 weeks. I dont know if there was a oil leak and the oil light did come on the night before her car broke down. I had a starter put in about 4 years ago.
