Do not change your oil viscosity. When people say you should run a different oil in different seasons/climates, do not listen to them. Whether it be a 20 degree winter or a 110 degree summer, the operating temperature of your engine will only vary by a small margin, and the manufacture knows this. The engine was built to run on 5w-30, so run 5w-30. It sounds to me like you're just getting excessive knock and need a tune, but i'm not in your car so i can't diagnose it properly. Good luck fixing it and let us know what the problem was.
