2012 3.6L pinging/knocking

I'm hoping that others here can do a quick test for me. I have a 3.6L 2012 JGC Laredo. Under normal driving load: going up a hill and usually around 2K RPM I get what I would call pinging or knocking. I can't hear it while idling or normal flat running speeds and it's more noticeable with the windows up.

You might be hearing the chain that drives the dual overhead cam.

It could also be bad gas. Try a different brand.
