That's too general of a description... when do you notice the knocking? i.e. what speeds, RPM, driving conditions, accelerating vs. cruising, etc. Any other symptoms or problems that go along with it? Could be as simple as the type of fuel you're using, or could be something more complicated - but we need to know more first.
a heavy knock is often associated with an engine problem. If you are encountering a heavy knock than try running a synthetic in the engine and see if it helps some. A light "ping" is often associated with what octane you run. While some of the auroras run fine on regular, others are so persnickity that they want and will drive properly only on premium.
