c230 engine shuts off right after start
 

Hi my mother has a 2000 mb c230 with 70000 miles and its having some problems. Yesterday it didn't really have much oil in it so she put in a quart and she pretty much drove all day with it. This morning I tried to start the car and the engine knocks really hard and then shuts off as soon as I take my foot off the gas. I checked the oil and there was no oil in the car. So I put 3 quarts in and it still has the same problem. There wasnt any leakage while I was running the engine with oil in it. Does anyone know what seems to be broken? thank you

Looks like its not maintained. Why is there little oil?

1st the car takes nearly six quarts.

also there is a shield under the engine that may be holding any leaking oil - but I kind of doubt that.

I know on my older nissan if the engine temp registered too high the car would cut off.

does the car have a full tank of gas?

and did you fill the oil up to the fill mark on the dip stick?
