Engine oil does not cause a engine knock. It is caused by pre-ignition, which can have many causes, including the wrong grade of fuel octane. Make sure that you are choosing the correct fuel for your vehicle. You may want to take the vehicle to a mechanic, as engine knocking can seriously damage your engine.
Noise is common from any engine, the TYPE of noise is what you should worry about. Is it a knocking noise? hum? squeak? rattle?
It depends on the type of "knocking noises" you're hearing. Usually knocking noises are caused either by spun or worn main bearings, or worn wrist pins. Either way, it means you need a new engine.
