Started knocking 2 days ago. Discovered it was 3 quarts low on oil. It is not leaking. Put oil in. Knocking has become worse. Really bad when accelerating. I just checked the oil and it is 1/2 quart low already. It has not overheated. The oil light never came on. The check engine light is not on. I can feel the knocking in the gas pedal as I accelerate.
