I noticed that when I am driving if the car goes above 3000 rpm I will hear a light knock type sound. It may be a tick or rattle but not quiet sure. My question is any idea of what it could be? Could it be something major w/high cost to repair or could it be something as simple as just needing an oil change? I know when I first bought the car about a month ago it was a little low on oil so I added oil to it so now it has the proper amount of oil. Im hoping its not something major. Please tell me that all I really need is an oil/filter change. Thank you.
